The surface treatment of the gear is processed to improve the surface state of the material. Generally, there are black treatment (surface oxidation), solid lubrication treatment, galvanizing, phosphorurative treatment, chemical silver plating, and raydent surface treatment. Their own characteristics of their own characteristics The description is as follows

1. Dark treatment (surface oxidation):

For alkaline black treatment: When placing metal in an alkaline treatment solution to 14ctc, the metal itself plays a chemical effect and forms a black skin film on its surface. The thickness of the black cortex is below, and the chemical ingredients are four -iron oxidation. The cortex has anti -rust effect.

2. Solid lubrication treatment:

Just spray the solid lubricant to the surface of the wheel tooth of the gear, and the lubricant that adheres to the surface to dry to form a skin film. The distan sulfide particles contained in the lubricant ingredients penetrate into the metal tissue to play a lubrication effect. Especially in the initial running of gears or preventing its lubrication effect on micro -movement caused by tiny friction movements. Generally used in a place where lubricating oil cannot be used

3. Galvanized:

Surface treatment for the purpose of improving the anti -rust performance of the metal. With the advancement of rhinate passivation treatment, the appearance performance has also greatly improved. The thickness of the plating layer is different, generally about 225 μm.

4. Phosphorusization treatment:

For phosphate treatment: Metal is immersed in the heating phosphate solution for chemical treatment, so that the metal surface forms a phosphate protective membrane. The anti -rust resistance of the phosphorized cortex has good abrasion resistance and lubrication effect, so it is mostly used in the treatment of sliding parts.

5. Chemical silver plating:

The corrosion resistance of chemical plating/abrasion resistance is high, and the silver -plated process does not pass electricity and electrolytic. Suitable for products with high size and accuracy requirements and complex shapes.

6. Raydent surface treatment:

Raydent treatment uses a method similar to electroplating to generate 1 ~ 2 μm thick black oxidized neat film on the surface of the mother material. Because the skin film and metal T book, it is very difficult to peel off. The rust resistance capacity is strong/wear -resistant capacity is improved, and the color is black.

Note:

1. Affected by the shape and size, the cortex cannot be uniformly formed inside the root of the teeth.

2. The corresponding occasions of ROHS need to be clearly specified to specify that the treatment of hexagonal chromium needs to be removed.
