Method of bonding a plastics body to metal.

摘要

A method of bonding a plastics body to a metal projectile, includes the steps of machining an annular recess or seat onto a projectile body and cleaning the recess. The next step includes coating the recess with metallic coating applied by a plasma flame spray process. A primer is then coated onto the metallic coated recess, the primer including a polymer disolved in a solvent. After drying the primer, the projectile is heated and a quantity of a polymer plastics material is injection molded into the recess to form the plastics body.
