Increasing the durability of agricultural machinery parts under abrasive wear by surface hardening

Abstract

This article examines the wear characteristics of agricultural machinery components operating under intense abrasive conditions. The influence of hard mineral particles, contact pressure, relative displacement, impact loads, and surface condition on damage formation is analyzed. The need for a comprehensive approach to increasing component life is substantiated. This approach encompasses not only increased hardness but also structural stability, crack resistance , and reliable interaction between the hardened layer and the base metal. Surface hardening, particularly diffusion chromium plating, is considered as a promising approach to improving the wear resistance of agricultural machinery components.
