A Way for Raising Corrosion Resistance of the Fasteners

Fasteners are widely used for agricultural vehicles. The fasteners based on steel matrix are easy to corrode in damp environment and cause hidden trouble to safety. In this paper, a kind of acid Zinc plating process is introduced. It can raise corrosion resistance of the fasteners. The technical formulation, process, process preservation and waste water processing were given detailed description. The production practices prove that the process is easy to operate, low in energy consumption and cost, in line with the policy of cleaner production (CP) of China. It can raise corrosion resistance, life span and use safety of the fasteners.
