Blast material for mechanical plating and continuous mechanical plating using the same.

摘要

A novel blast material for the mechanical plating and a novel continuous mechanical plating process are disclosed. The novel blast material comprises not less than 10% by weight of an alloy powder which comprises 2.5 - 50% by weight of iron, not more than 5% by weight in total of at least one of aluminum, copper, tin, magnesium and silicon, the balance being zinc, and has a particle diameter of substantially not larger than 0.4mm and an average hardness of 140 - 450 Hv, and up to 90% by weight of steel shot. The novel continuous mechanical process comprises continuing blasting, recycling the used blast material and magnetically separating the abraded fine particles of the steel shot in the course of the recycling.
