60 Excellent Inventions in Metal Forming

Abstract

A non-reactive cold forging coating, named as dry in-place coating, is developed to replace zinc phosphate coating for cold forging operations. This new coating is formed by dipping the billet into liquid lubricant bath with subsequent drying, and consists of two layers; the upper layer provides a low friction with the tool surface and the lower layer protects the tool surface by avoiding direct contact with the billet surface. The new coating has been used successfully for closed die forging of inner racers, tripods, pinion gears and introduced in 13 countries.
