Conclusions
-
1.
It is recommended that thermal stabilization of iron piston rings be done in the 600–620°C range, which provides a polygonization structure and the maximum strength and elasticity.
-
2.
Alloying of irons with cerium makes it possible to broaden the thermal stabilization temperature range, to provide stabilization of the polygonized structure, and to strengthen the resistant to recrystallization.
-
3.
Irons with spheroidal and vermicular graphite posses higher elasticity and heat resistance than special gray irons.
