Increasing the efficiency of forging tools by Toyota diffusion process

Abstract

In this paper is given a review of literature data about research of influence layer of vanadium carbide deposited by Toyota diffusion process on increasing of working life and quality of forging dies. Forging dies are subjected to severe adhesive and abrasive wear, high stresses and temperatures. The die surface and near surface region is subjected to the most severe conditions during forging and hence most defects and causes of failure of the dies originate from this region. Because of this, paper takes into consideration the different complicated mechanisms of wear and the destruction of the surface of tools for forging, apropos that network of various aspects which affect on the service life of the tool and by their actions causing premature removal tool from the use.
