Abstract

This article describes problems related to the lifetime of tools used for hot forging. The results of industrial tests, involving the application of ZeroFlow nitriding for the purpose of improving tool lifetime, are presented. One of the bottom dies was subjected to detailed analysis on account of its short lifetime. Analysis of a standard die was also conducted for the purposes of comparison. Based on comprehensive tests of tools (surface scanning, microhardness measurements, observation under a microscope), after a specific number of manufactured forgings, it was demonstrated that the application of ZeroFlow gas nitriding can effectively increase the lifetime of tools used in hot die forging processes.

Keywords: forging tools, forging, ZeroFlow method, nitriding.
