Abstract: Studies of the tribological properties of electrospark coatings on steel 45 prepared by processing with electrodes made of chromium, molybdenum, BrOF6.5-0.15 grade bronze, and a T15K6 hard alloy are described. The studies were conducted in a cell according to three test patterns using and cutting fluid and MGE-46V hydraulic oil under different loads. The first-pattern tribological tests showed that the chromium coating is the most wear-resistant (U = 0.7 mg) and the coating of BrOF6.5-0.15 grade bronze exhibits the lowest antiwear properties (U = 4.7 mg). The second-pattern wear tests also revealed that the highest and lowest wear resistance is exhibited by the chromium coating (U = 0.4 mg) and the BrOF6.5-0.15 bronze coating, respectively. According to the third-pattern tests, the highest wear resistance was found for a composite coating of a T15K6 hard alloy + BrOF6.5-0.15 bronze (U = 0.8 mg), while the lowest antiwear properties were exhibited by the BrOF6.5-0.15 bronze coating (U = 6 mg)
