Surface treatment options supported by CNC machining
Anodic oxidation |
Type II anodizing improves corrosion resistance and can be used as a basis for surface treatment of paints and other finishes. Note: The anodizing effect may vary among different materials.
Note:
Using dyes to affect the surface color of parts
Type II coating is prone to wear and may bleach or fade under prolonged direct sunlight
Can customize color (RAL) |
Dusting |
Use uniformly applied thermosetting coating to provide a continuous protective color surface for the parts. Compared to traditional spray painting, powder coating surface treatment is usually tougher or even more uniform. Metals such as aluminum and steel can be effectively coated with polymer powder.
Note:
There are many options for powder coating, and customers need to choose different types of powder coating based on the functionality of the product |
Electropolishing |
Electrolytic polishing refers to an electrochemical process that can clean steel components, reduce corrosion, and improve appearance by making the metal brighter. However, electrolytic polishing may have a certain impact on product size (reduction) while improving the surface smoothness of the product.
Note:
Reduce corrosion
Brighter appearance |
Passivation |
This is a colorless coating that improves the corrosion resistance of 200 series, 300 series, and age hardened corrosion-resistant stainless steel by removing surface burrs.
Size changes: Passivation treatment may cause small changes in metal size
Surface roughness: Passivation treatment may result in a slight increase in surface roughness.
Not applicable to all metals: Passivation treatment is typically used for metals such as steel and stainless steel, and may not be suitable for some other types of metals. |
Electroless nickel plating |
Chemical nickel plating refers to the application of a uniform nickel coating on the surface, which can prevent corrosion, oxidation, and wear of irregular surfaces.
The wear resistance of nickel plated coatings may be relatively low, especially under high friction or wear conditions, where the coating may be damaged.
Nickel plating coating may affect the weldability of the product, making the welding process more difficult.
Note:
Prevent corrosion, oxidation, and wear of irregular surfaces
Brighter appearance |
gold-plating |
Gold plating has good corrosion resistance and rust resistance. Gold plating has low contact resistance, excellent conductivity, and solderability.
Note:
Golden like appearance
Improve corrosion resistance and rust prevention ability |
Electroplated/hot-dip galvanized |
Electrogalvanizing/hot-dip galvanizing refers to the electroplating of a thin layer of zinc metal onto the surface of another metal object (called a substrate). The zinc coating forms a physical barrier to prevent rust from reaching the underlying metal surface.
1: Galvanized coatings may reduce the electrical conductivity of metals, which may be a disadvantageous factor for certain electrical applications.
2: Once the galvanized coating is damaged, repair or maintenance may be relatively difficult.
3: The presence of galvanized coating may increase the hardness of the metal surface, thereby reducing the plasticity of the metal.
4: Galvanized surfaces may affect the welding performance of products, as the presence of zinc may result in the production of undesirable gases during welding, affecting welding quality.
5: Galvanized coatings may become brittle under certain conditions, especially at high temperatures, which can lead to cracking or detachment of the coating.
Note:
Improve corrosion resistance |
Blackening (black oxidation) |
Black oxide is a coating formed by the transformation of ferrous materials (such as steel and stainless steel), which can cause the surface of the material to turn black. It can be used to reduce reflection and glare, and has a certain degree of corrosion resistance without affecting part size. |
Annealing |
Annealing is a metal heat treatment process. The annealing process refers to heating a metal to or near the temperature at which recrystallization begins without changing the stress. After heating, the metal is usually cooled to room temperature in an oven or in sand.
Effect:
Improving the cold working ability of metals helps to reduce their hardness and improve their mechanical properties, making them easier to process and form the desired shape. |
Surface hardening (nitriding) |
Surface hardening is a heat treatment process that hardens the surface metal while maintaining the softness of the underlying metal. As the name suggests, carburizing is the process of introducing carbon or nitrogen into low-carbon alloys at high temperatures to increase surface hardness. It should be noted that nitriding treatment may increase surface roughness, improve the hardness and wear resistance of the metal surface. |
Tempering |
Tempering is a heat treatment method that involves heating a metal to a temperature below the critical point and then reducing its hardness. The temperature is adjusted according to the required reduction in hardness and varies depending on the type of metal.
Note:
Reduce hardness
Increase elasticity and plasticity
Reduce yield strength and tensile strength |
Quenching |
Quenching is different from surface hardening in that it not only hardens the surface, but also gives the entire alloy a relatively similar hardness. This can be achieved by introducing carbon into the alloy matrix and repeatedly quenching it in salt water or water, or by oil quenching. It should be noted that the quenching strength needs to be determined based on the characteristics of the material. If the quenching requirement is too high, it may cause the product to crack.
Note:
Hardened surface layer, wear-resistant, wear-resistant, and deformation resistant
The internal core of the material maintains toughness and ductility |
Hard anodizing (type III) |
The hard anodized (Type III) layer can produce a thicker standard anodized layer, making it more durable and wear-resistant. Can be used as a base for paint or other finishes.
Note:
Due to thickness, the color may appear slightly darker
Can request custom color (RAL) |
Customized |
If you choose custom surface treatment in the IQE real-time quotation engine, it will require manual review by the Xomtry Power Technology engineering team, which usually takes 1-2 working days.
Note:
The manual review of custom surface treatment requirements by the engineering team does not guarantee a 100% quotation. |
