Application of heat treatment in wear protection for working parts of agricultural machinery

In this paper, the results of investigating the wear by abrasive particles with different velocities of the samples made of C45 steel in the normalized state, and samples of the same steel subjected to quench hardening as well as boronizing. As an abrasive in the experiment, a soil sample with a sandy loam texture label was applied. The research was conducted with the aim of determining the best application of the above- mentioned heat treatment procedures of wear protection on agricultural machinery. During the exploitation of agricultural machinery, the working parts of machines and tools for tillage are exposed to the different types of wear. The most dominant wear mechanism is abrasion, which occurs due to the direct contact of the working surfaces of the tool with the soil particles. This wear is manifested by a change in the shape of the working parts, which causes a decrease in the efficiency of machines thus requiring frequent renewal of worn parts and increased maintenance costs of agricultural machinery. The research proved a significantly lower wear of samples subjected to quench hardening as well as boronizing compared to steel in the normalized state, thus proving the justification of the application of these treatments as wear protection of parts of agricultural machinery.
