Rationale for the choice of wear-resistant coatings in the hardening of tillage working bodies of forestry machines

[摘要] The article deals with the interaction of soil-cutting elements of forestry machines with soil and trees and shrubs. It substantiates the statement that when choosing wear-resistant coatings when hardening tillage working bodies, it is necessary to take into account the composition and physico-mechanical properties of the soil. The method of choosing wear-resistant coatings depending on the hardness of abrasive particles of soil mass is considered. According to the results of experimental studies in the hardening of soil-cutting elements, it is recommended to use flame spraying of wear-resistant coatings from self-fluxing alloys.
