Working elements of agricultural and road-construction machinery operating in abrasive environments often fail prematurely due to intensive wear. Therefore, increasing their wear resistance is an important and relevant task. This scientific article presents the results of laboratory, bench, and field tests of the undercarriage components of tracked machines whose working surfaces were strengthened with wear-resistant coatings. Borided and boron-titanized coatings were formed on the working surfaces of the support and drive rollers, while composite bimetallic coatings based on PG-S27 “sormite” with the addition of boron carbide were formed on the running track of the track link directly during the casting process. Numerous tests have shown that the developed technologies for forming wear-resistant coatings on the working surfaces of friction parts of the undercarriage of tracked machines ensure a 5–7 times increase in wear resistance. This represents an effective solution to one of the most significant operational problems of machinery operating under conditions of intensive abrasive wear.
