Plating effect:
The quality of electroplating is based on its corrosion resistance, followed by appearance. Corrosion resistance is to imitate the working environment of the product, set as the test condition, and conduct corrosion test. The quality of electroplated screw is controlled in the following ways:
1. Appearance:
The surface of the zinc plating screw is not allowed to be partially uncoated, charred, rough, dull, peeled, crusted and marked. It is not allowed to have pinhole pitting, loose passivation film, cracking, shedding and serious passivation traces.
2. Coating thickness:
The working life of a screw fastener in a corrosive atmosphere is proportional to its coating thickness. The recommended economical plating thickness is generally 0.00015 inch to 0.0005 inch (4 to 12 um).
