Increasing the wear resistance of reworked parts of transport engines

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.
