Claims
- 1. A continuous mechanical plating process comprising projecting a blast material consisting of a mixture of 60-970% by weight of steel shot and 10-40% by weight of a coating alloy powder comprising 2.5-50% by weight of Fe and a maximum of 5% by weight of at least one of Al, Cu, Sn, Mg and Si, the balance being Zn and inevitable impurities, said coating alloy powder having an average hardness of 140-450 Hv, onto the surface to be treated, and projecting said blast material repeatedly, characterized in that a magnetic separation step is interposed in the course of repetition of the projecting, whereby fine iron powder produced during blasting is removed from said mixture.
- 2. The continuous mechanical plating process as set forth in claim 1, wherein said steel shot material has a minimum size of about 0.25 mm, and at least 70% by weight of said shot material has a maximum size of about 0.4 mm.
- 3. A continuous mechanical plating process as set forth in claim 1 wherein said alloy powder has a maximum particle size of about 0.4 mm and at least 80% by weight of said powder has a particle size less than about 0.25 mm.
- 4. A continuous mechanical plating process is set forth in claim 2 wherein said alloy powder has a maximum particle size of about 0.4 mm and at least 80% by weight of said powder has a particle size less than about 0.25 mm.
