Abstract
Calculation method is presented for evaluation of the range of optimal parameters for the technology of corrosion-resistant surfacing of shafts in ship mechanisms and systems. The method is based on taking into account the potential formation of fatigue cracks at cyclic loading in service.
Keywords: shafts of ship mechanisms, surfacing, defects, hot and cold cracks, microstructures, residual stresses, fatigue resistance
