Resumo

The article describes new mixed technology for increasing the wear resistance of parts of transport engines based on the example of a crankshaft. The basis of the new mixed technology is the heat treatment of crankshaft pins and the application of a multilayer antifriction coating in one technological cycle. Laboratory tests on mixed technology application revealed an increase of wear resistance of crankshaft pins, a reduction in the coefficient of friction, a reduction in the running-in period, and an increase in the scoring resistance and operating life of the crankshaft.
