RESEARCH ON INCREASING THE HARDENING OF A GEAR REDUCER USING PLASMA TECHNOLOGY

Abstract

Different case hardening methods are used to increase the hardening of machine-building products and their resistance to abrasion, temperature and corrosion. The most modern methods include plasma nitriding technology. This method can be applied for the following parts: crankshaft, gears, piston parts, etc. A common characteristic feature of workpiece that undergo case hardening is that their mechanical processing after hardening is difficult or impossible due to high hardness and complex geometric shape. Plasma nitriding is the process of low-temperature common case hardening for highly loaded gears. When nitriding, a diffusion layer with very hard complex nitride precipitation with a thickness of several microns is formed on the surface of the gear wheel, which greatly increases the technical performance of the part. [1] This article summarizes the state of knowledge in the field of plasma nitriding technology equipments and surface nitriding of gears, provides a overeview of the current state of research in the field of nitrided gears. Keywords: hardening, plasma nitriding, nitriding, gears, mechanical processing, reducer.
