Steel, copper and aluminum can all be electroplated or painted in principle, but anodic oxidation is mainly aimed at the different functions of aluminum products in the future.
Other colored and cleaned metals can be used as stainless steel parts such as electronic products, and many of them can be electroplated or cleaned after stamping. etc
What kind of surface treatment method to choose depends on what kind of product performance and appearance are needed in the future.
Question 2: There are too many kinds of surface treatments for metals, which can be divided into four aspects:
1. Mechanical surface treatment: sandblasting, shot blasting, polishing, rolling, polishing, brushing, spraying, painting and oiling.
2. Chemical surface treatment: bluing and blackening, phosphating, pickling, electroless plating of various metals and alloys, TD treatment, QPQ treatment and chemical oxidation.
3. Electrochemical surface treatment: anodic oxidation, electrochemical polishing and electroplating. .........
4. Modern surface treatment: chemical vapor deposition CVD, physical vapor deposition PVD, ion implantation, ion plating and laser surface treatment.
What is listed above is aspects, not categories. For example, sandblasting includes dry sandblasting, wet sandblasting, atomized sandblasting and air-water sandblasting. Spraying includes electrostatic spraying, flame spraying, powder spraying, plastic spraying, plasma spraying and explosive spraying. Electroplating includes copper plating, chromium plating, zinc plating and nickel plating ... Electroplating processes, such as copper plating alone, can be divided into acidic copper plating and alkaline copper plating according to different PH values. According to the main salts formed by copper ions and the main components of electrolyte, there are cyanide copper plating, pyrophosphate copper plating, citrate copper plating, sulfate copper plating, tartrate copper plating, fluoroborate copper plating and its bright copper plating.
How many kinds are there? I didn't count it. It is estimated that there are dozens or hundreds. Some adapt to metal materials, and some adapt to non-metal materials.
Question 3: What kinds of metal surface treatments are there, such as alloy catalysis, nano-spraying, electroplating and so on?
Question 4: What are the methods of metal surface treatment? Stainless steel: electroplating, polishing, wire drawing, electrophoresis, PVD, etching and color passivation.
Aluminum alloy: anodizing, electroplating and etching.
Magnesium alloy: electroplating and passivation film
Titanium alloy: electroplating, anodizing
Zinc alloy: electroplating, passivation
Cast aluminum: electroplating, anodizing
Iron and steel: passivation, phosphating
Question 5: What is the practical significance of metal surface treatment technology to increase corrosion resistance, weather resistance, acid resistance, alkali resistance, oil resistance, heat resistance, impact resistance, adhesion and hardness?
Question 6: What is metal surface treatment arcor? Arcor is salt bath carburizing, which is a surface treatment technology invented by HEF company in France.
This technology is the introduction of French HEF patents Shechev and Arco technology. SURSULF technology is characterized in that the concentration of active sulfur atoms in the salt bath is kept at a constant level, and the density and hardness of the bonding layer only depend on the contents of carbon and other alloying elements in the steel to be treated. After treatment, with the increase of alloying elements such as carbon in steel, the hardness gradient of diffusion layer becomes steep; The depth of the diffusion layer becomes smaller. In order to be applied to occasions requiring high corrosion resistance, ARCOR treatment process can be used as a supplement to Sheshev treatment process. It is a treatment process combining thermochemical diffusion, passivation and precision treatment in a salt bath furnace. A surface layer with high friction resistance, bite resistance, wear resistance, corrosion resistance and high fatigue strength is formed on the surface of the workpiece. It is suitable for any workpiece that needs to solve the problems of friction resistance, bite resistance, wear resistance and corrosion resistance, and is an ideal treatment process with low price.
Question 7: What stainless steel is used for metal surface treatment? Electroplating, polishing, wire drawing, electrophoresis, PVD, etching and color passivation.
Aluminum alloy: anodizing, electroplating and etching.
Magnesium alloy: electroplating and passivation film
Titanium alloy: electroplating, anodizing
Zinc alloy: electroplating, passivation
Cast aluminum: electroplating, anodizing
Iron and steel: passivation, phosphating
Question 8: The difference and connection between metal heat treatment and metal surface treatment are inaccurate, and only some perceptual knowledge can be given:
Heat treatment mainly includes: quenching, tempering, annealing, tempering, etc. The purpose is to change the mechanical properties of metal materials; All related to heating;
Surface treatment includes too many contents: painting (painting, plastic spraying), hot dip plating, electroplating, oxidation, bluing, coloring, phosphating, passivation, pickling, chemical polishing, electrolytic polishing, electroforming, shot blasting, sanding, wire drawing, vibration light, flame spraying, carburizing and nitriding. ....
The purpose of surface treatment is to prevent corrosion, and secondly to improve the appearance quality; But carburizing and nitriding are to change the mechanical properties of metal materials; Most surface treatments have nothing to do with heating.
Question 9: What kinds of metal surface treatments are there? The main types of metal surface treatment include electroplating, painting, coloring, anodizing and cleaning, etc., and the small ones are not illustrated by examples.
Iron, steel, copper and aluminum can all be electroplated or painted in principle, but anodic oxidation is mainly aimed at the different functions of aluminum subsequent products.
Other colored and cleaned metals can be used as stainless steel parts such as electronic products, and many of them can be electroplated or cleaned after stamping. etc
What kind of surface treatment method to choose depends on what kind of product performance and appearance are needed in the future.
