How Many Surface Finishes Treatment You can Select From ?



How Many Surface Finishes Treatment You can Select From ?

Surface finish treatment is forming a surface layer process method on the substrate material surface, 

which has different mechanical, physical and chemical properties with substrate material.

The purpose of surface treatment is to meet the product corrosion resistance, wear resistance, decoration or other special functional requirements.

Depending on the usage, the surface treatment technique may be classified into the following categories.

Electrochemical method

This method is the use of electrode reaction to form a coating in the workpiece surface.

The main methods are:(A) Electroplating   (B) Anodization

Chemical method

This method is using chemical interaction without current to form coating film 

on the workpiece surface. The mainly methods are:

(A) chemical conversion film treatment (B) Electroless plating

Thermal processing method

This method is making the material melting or thermal diffusion in the high temperature conditions to form coating film on the surface of the workpiece.

The mainly methods are:(A) Hot dip plating (B) Thermal spraying (C) Hot stamping(D) Chemical heat treatment

Other methods

Mainly mechanical, chemical, electrochemical, physical method. The main methods are:(A)Painting coating  (B) Strike plating  (C) laser surface finish  

(D) Super-hard film technology (E) Electrophoresis and electrostatic spraying
