| description | The article considers the issues associated with the evaluation of hardening treatments influence on the service life of the piston ring in the cylinder of a heavy-duty diesel engine. The statement about the high efficiency of laser hardening of cylinder liners made of cast iron is substantiated. Model experiments on a laboratory friction machine investigate the wear resistance of the friction surfaces of the coupling piston ring-cylinder liner. The effect of piston ring wear on the loss of elasticity and the service life of the coupling is analyzed. The calculation method determines the service life of the coupling and analyzes the efficiency factor of the laser hardening treatment. On the basis of the study, it was found that laser hardening of the friction surfaces of cast-iron cylinder liners has a positive effect on the coupling wear resistance, but increases the wear of the piston rings. To eliminate the increase in wear resistance of piston rings, it is proposed to make them from steel and apply laser treatment of a wear-resistant coating from a high-entropy alloy of the Fe-Cr-W-Mo-Co-Ni system, which can significantly increase the service life of the piston ring-cylinder liner coupling in heavy diesel engines. |
