The occurrence of anode effects is because as the electrolysis process, oxygen-ion electrolyte gradually reduced, when a certain degree, there is precipitation of fluorine and carbon generate carbon anode effects fluoride, carbon fluoride in the decomposition time and fine carbon particles deposited on the carbon particles attached to the surface of the anode, electrolyte and anode to prevent contact of the electrolyte cannot properly wet the anode, like water cannot wet oiled surface as the electrolyte - anode formed between a bad air film conductive layer, the anode overvoltage increases, causing anode effect. When adding a new alumina deposited on the anode and oxygen, the reaction of oxygen and carbon black, the anode surface gradually quiet, resistance is reduced, the electrolysis process and become normal.
After 40 years of research and development, electrolytic coloring to keep the depth and breadth of development, anodized aluminum is developed from the general protective - decorative purposes to the functional film special physical and chemical properties, from single colored salt to mixed salt coloring, from single uniform color to multi-colored, multi-color sense, and so on. Current porous alumina membranes toward functional direction research mainly from two aspects, one is the use of its porous structure, the development of new ultra-precision membrane; the other is through their nanoscale pores of various deposition the nature of different substances, such as metal-semiconductor, polymer materials, to prepare a new type of functional materials.
- Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter
- in the experience that your speaking a pair of folding pocket knife, i think of that it somewhat is somewhat six one way and a 0.5 dozen the different. i actually do choose stainless for my pocket knives. i don't choose to grease a knife to the degree i've got faith carbon demands, basically to then stick it my pocket to entice dirt to the knife and oil to my pants. i'm the impressive opposite on sheath knives nevertheless. i admire 1095 carbon steel, uncomplicated part sheath knives. i will thrash on them difficult, and that i rarely have considerable part issues. of course, I require them to be lined with some style of powder coat or the like, with the aid of fact they might rust, yet I do attempt and save them sparkling and dry whilst in the sheath, so as that they gained't pit the uncoated part. My motives for this sheath knife selection is multi-fold. First, those knives are only much less costly. i don't spend $80 money on a exterior sheath knife. i take advantage of the gadget too difficult to choose to spend extra. i don't basically like the extra classic stainless steels alongside with AUS-8, 420HC, and 440C (to not point out the HORRENDOUS 440A) with the aid of fact i've got faith that the all else being equivalent, a stainless blade will bend till now a carbon blade will harm. I additionally think of that carbon holds an part a minimum of besides, if not extra suited, than classic stainless, and it somewhat is plenty extra handy to hone. i don't understand plenty approximately those new laminates, different than the very difficult, yet not so difficult. they seem probably too brittle for my use. That, mixed with the actuality that they harm the bank, ability that I only is only not pondering them.
- Q: What are the different types of steel coil surface defects?
- During the manufacturing or handling process, various steel coil surface defects may arise. Some commonly encountered types are as follows: 1. Rust: When moisture or oxygen comes in contact with the steel coil, rust, a reddish-brown discoloration, may develop on its surface. 2. Scratches: While the steel coil is being handled or transported, superficial marks known as scratches can be incurred. These marks can vary in depth and severity, ranging from light surface scratches to deep gouges. 3. Stains: Exposure to chemicals or other substances can lead to stains, discolored patches that appear on the coil's surface. Removing them may prove to be challenging. 4. Roll marks: During the rolling process, impressions or indentations called roll marks may form. Uneven pressure or misalignment of the rolls causes them, resulting in lines or patterns on the coil's surface. 5. Edge wave: Imperfectly flat edges of the coil can result in a defect known as edge wave. This defect causes the edges to appear wavy or uneven and can impact the coil's overall appearance and performance. 6. Oil spots: If the oil or lubricants utilized in the manufacturing process are not adequately removed, surface defects called oil spots can manifest. These spots appear as dark patches or spots on the coil's surface and may hinder the adhesion of coatings or paints. 7. Pitting: Small, shallow depressions or pits on the coil's surface are indicative of a defect called pitting. Factors like corrosion, uneven cooling, or impurities in the steel can cause this defect. 8. Holes: Holes are severe surface defects that can arise due to various factors, including corrosion, mechanical damage, or manufacturing errors. These defects come in different sizes and can significantly compromise the coil's structural integrity. Promptly addressing these surface defects is crucial for maintaining the quality and performance of the steel coil. Regular inspections, proper handling, and appropriate surface treatments can help minimize the occurrence of these defects.
- Q: I want to save water $$, so I want to use frozen steel to cool my coke. possible or no?
- can't freeze it but ya can make it very cold
- Q: hello guys. im totally new to this metalwork things. i need to do it for my project. i need to join stainless steel wires to build some kind of structure (eiffel tow. for example).i already have the wire and the torch. now the question is: where do i get silver solder? is it expensive? and what is flux for? is it necessary? what does it do? is it expensive?thank u for ur time guys! :)
- Silver Solder is more expensive than lead/tin solder as it contains silver. It also melts at a much higher temperature. You require special Flux designed for stainless steel and silver solder. Cost of Silver Solder and Flux will depend on the quality, quantity, and where you are located. Prices vary from area to area especially country to country. Instructions: 1: Clean all surfaces to be soldered with solvent and a wire brush to remove all grease, corrosion or dirt. 2: Apply a coating of flux to the stainless steel parts you are connecting. If you are soldering brass or copper parts to the stainless steel, tin them first by heating them and applying a thin coat of solder to the area that connects to the stainless steel. 3: Hold your parts together with wire or clamps. Make sure the surfaces fit flush. Silver solder will not fill gaps. 4: Heat the parts with a torch until the solder flows onto the joint. When the parts are hot enough, the solder will instantly turn to liquid when it touches the metals, then it will flow into the joint. If it does not do this, keep heating the metal until it does, but do not heat the solder directly. Only allow the hot metal to melt the solder. 5: Remove the torch and solder as soon as a sufficient amount of solder melts onto the joint. You don't need much, and a glob can look ugly. 6: Allow the metal to cool before touching or cleaning it. You can dunk it in water to cool it faster.
- Q: How are steel coils inspected for defects after recoiling?
- Steel coils are inspected for defects after recoiling by conducting visual inspections, using non-destructive testing methods such as ultrasonic testing or magnetic particle inspection, and conducting measurements to check for dimensional accuracy and straightness.
- Q: What are the typical dimensions of a steel coil?
- The typical dimensions of a steel coil can vary depending on its purpose and the industry it is being used in. However, in general, steel coils are often manufactured with a width ranging from 0.5 to 2 meters (1.6 to 6.5 feet) and a thickness between 0.1 to 25 millimeters (0.004 to 1 inch). The outer diameter of a steel coil typically ranges from 800 to 2,000 millimeters (31 to 79 inches), while the inner diameter, known as the core, can range from 500 to 1,000 millimeters (20 to 39 inches). These dimensions can be customized to meet specific requirements and can vary between different manufacturers and applications.
- Q: How are steel coils tested for tensile strength?
- Steel coils are typically tested for tensile strength using a method called tensile testing. This involves subjecting a sample of the steel coil to a controlled pulling force until it breaks. The force required to break the sample is then measured, providing an accurate measure of the steel's tensile strength.
- Q: what is the difference between metal and steel
- well, steel is a type of metal. It's sort of like asking the difference between a bug and an ant, an ant is a bug, but not every bug is an ant. Likewise, steel is metal, but not all metal is steel. Gold is metal, Silver is metal, Iron is metal, Steel is metal.
- Q: I am looking for steel. I need a lot.
- Not sure what the question is. Oh...and this isn't a place for classified ads.
- Q: How are steel coils weighed?
- Steel coils are typically weighed using industrial weighing scales or load cells. These devices are capable of accurately measuring the weight of the coils, whether they are small or large in size. The coils are placed on the scale or load cells, and the weight is digitally displayed or recorded for further analysis or documentation.
