Abstract
The paper presents data on a technical condition of cast iron crankshafts to be repaired which is characterized by wear of crankshaft necks and connecting rod journals and misalignment of crankshaft necks of ZMZ-53-engines. Wear and misalignment of crankshaft necks are closely described by the the Weibull's law and 70–75 % of the shafts to be repaired require recovery with deposition of coating. In order to recover crankshaft necks it is proposed to apply plasma spraying with a mixture of powders which includes copper powder. Coating obtained in accordance with the proposed technology is characterized by wear intensity during its normal operation 4,0 · 10–6 g/m, and it is by 3–5 % lower than the wear intensity rate of those shafts that have been recovered with the help of spraying powder mixtures without copper.
