Development Technology for Increasing Durability and Longevity of Soil-processing Working Bodies

Abstract

The article deals with the technological process of obtaining metal layered compositions (MLC) for tillage working bodies. Metallic layered compositions are given that were developed for various types of tillage working bodies. The stavas of the Fe – Cr – C system served as “inserts”; namely, ПГ-С27and ПГ-С27-ТН-20, and the supporting base is foundry structural steel 65GL. Based on the studies (studying the microstructure, micro-hardness, distribution of elements in the transition zone, x-ray phase analysis), technologies have been developed for obtaining a number of MLCs for tillage tools.
