Abstract

Composite Fe n B-Fe-B boride coatings were obtained on the surface of agricultural machine details, such as arrow-shaped pads made of 65G steel with a velocity RF-borating process. Four embodiments of the reaction mixtures were tested that form the coatings of different types, compositions, and structures during boriding. Tribotechnical tests of the isolated coatings in the laboratory showed a complex mechanism of wear by friction on the flexibly attached abrasive with a formation of transfer areas at the boundary between the coating and the abrasive. The wear of arrow-shaped pads strengthened with composite boride coatings during real running-in is 1.5–3 times smaller than for the control samples.
