Abstract
The way of evaluation and monitoring of the inhomogeneity degree of the stress-strain state of oil scraper piston rings of diesel generator D100 by the coercive force measuring and change the lock line size before and after hardening by the ion-plasma coating is shown. Evaluation of stresses by optic-mathematical method after preliminary bench testing on friction and wear is done.
