Wear resistance of blade and disc working bodies of tillage tilling machines hardened by electrodes T-series

Abstract

Based on a systematic analysis of methods to increase the durability and wear resistance of the working bodies of tillage machines, it is established that their increase in 90% of cases is achieved by technological methods. In turn, this requires the use of expensive reinforcing materials, which leads to an increase in the cost of the final product. The solution of such a complex problem cannot be based on the use of one group of methods, but requires an integrated approach using a range of available groups of methods. Accordingly, the purpose of the work is to determine experimentally possible methods to increase the durability and wear resistance of the working bodies of tillage machines, taking into account the soil and climatic conditions of their operation. In the work, on the basis of soil-climatic conditions of operation of working bodies of tillage machines, operational, constructive and technological methods of increase of wear resistance of ploughshare and disk working bodies are experimentally established. Wear of the working bodies of tillage machines is complex. The problem of increasing the wear resistance and durability of working bodies that interact with the soil environment cannot be solved by using only technological methods to increase wear resistance and durability.
