Surface nitriding of sliding faces - by ion bombardment with screened edges

摘要

Workpieces with sharp edges are nitrided on the surface with a partial suppression of the edges flexures upwards. A convex shape across the width is produced by effecting diffusion in an electrical glow discharge by ion bombardment in a gaseous atmos. contg. diffusible substances. The edges are screened against ion impact during this treatment.
