Black Zinc Plating Torx Micro Screw Details
Steel can easily rust or even be completely damaged in air, water or soil. The annual loss of steel due to corrosion accounts is about one-tenth of the total steel production. On the other hand, in order to give the steel products and parts surfaces a special function, while giving them a decorative appearance, it is generally electrogalvanized.
Black Zinc Plating Torx Micro Screw Application
Black Zinc Plating Torx Micro Screw Production Flow
The zinc is not easily changed in dry air, in the moist air, the surface can form a very dense basic zinc carbonate film, which can effectively protect the interior from corrosion. And for some reason, when the coating is broken to expose a steel base that is not too large, the zinc and the steel substrate form a microbattery, and the steel substrate is protected as a cathode.
Performance characteristics of zinc:
1. The zinc coating is thick, the crystal is fine, uniform and non-porous, and the corrosion resistance is good;
2. The zinc layer obtained by electroplating is relatively pure, and the corrosion is slow in acid, alkali and other mists, which can effectively protect the steel matrix;
3. The zinc coating is passivated by chromic acid to form white, color, military green, etc., which is beautiful and has certain decorative properties;
4. Since the zinc plating layer has good ductility, various forms such as cold punching, rolling, and bending can be performed without damaging the plating layer.
