(3) For some use of special paint spraying should be baked, of course, depending on the size of the area, small can be placed in the oven, large can only be dried first, and then to dry parts for processing, lock baking, if other circumstances can only use high temperature tools bit by bit baking. The products that can be baked in the oven should be leveled at room temperature for 15 to 30 minutes, baked at a low temperature of 60 degrees Celsius for half an hour, and then baked at the reserved baking temperature for one and a half hours, and then cooled down.

In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.

The chromium-plated layer has good thermal property. When the temperature is heated below 500℃, its luster and hardness are not changed obviously. When the temperature is higher than 500℃, the initial oxidation and discoloration occur, and the hardness decreases when the temperature is higher than 700℃. The friction coefficient of chrome coating is small, especially the dry friction coefficient, which is low among all metals. So the chrome coating has good wear.
