Increasing the anti-friction properties of the surfaces of machine parts through plasma spraying of powder coating PG-19M-01 instead of cast bronze bushing

Abstract

The anti-friction properties of the plasma-sprayed powder coating based on copper PG-19M-01, proposed instead of the cast bronze sleeve made of 05Ts5S5 bronze, used in the coupling of the drive shaft and gear of the T-155 transfer case pumps, were proposed and investigated in the paper. X-ray phase analysis of plasma coatings from PG-19M-01 powder showed that the main phase in the coatings is a solid solution of aluminum in copper. X-ray microspectral analysis established that the composition of the coating is heterogeneous in thickness. The results of the conducted research and field tests showed that plasma coating with copper-based powder PG-19M-01 has higher tribotechnical characteristics compared to cast bronze 05Ts5S5.
