Abstract

PURPOSE: To enhance wear resistance and baking resistance by using specific materials for the parts of rotor housing, vane, rotor.
CONSTITUTION: The rotor housing 1 is made of a boron-cast iron obtained by crystallization of a carbide and flaky graphite in the base material pearlite or martensite, and the vane 4 is made of a Cr-plated material. The boron-cast iron, having highly hard carbide crystallized, has excellent wear resistance and also improved lubricity due to the presence of flay graphite, as well as improved baking resistance due to the presence of graphite having a very high melting point. The vane 2 sliding with the boron-cast iron, which is plated with Cr(chromium), has small frictional coeffcient and excellent wear resistance and therefore exhibits better sliding characteristics.
