摘要：

The results of tribotechnical testing of brass-steel and iron-steel friction couples for both their running-in ability and wear resistance have been described. For brass and iron jaws of friction couples, it has been established that the load before tearing increased to 4.3 and 12.3%, respectively, in synthetic oil, while for semisynthetic oil, it increased to 12.5 and 25.0%. It has also been found that ultrasonic machining enabled a decrease in the coefficient of friction for brass and iron jaws in synthetic oil to 13.4 and 15.3%, respectively, and 25.0 and 28.1% in semisynthetic oil. Any features of the residual viscosity of engine lubricating oil after ultrasonic machining, which cannot be measured with a fluidmeter, have been found.
