Abstract
PURPOSE: To make difficult the wear of the journal of a turbine rotor made of steel containing 12% of chromium, by providing a quenched or nitriding layer on the surface of the journal.
CONSTITUTION: Before a turbine rotor 1 made of steel containing 12% of chromium is fitted in a bearing 7, high-frequency quenching or nitriding is effected on the surface part 3 of the journal 2 of the rotor so that the surface part is hardened with residual high compressive stress therein. This results in making it difficult for the journal 2 to wear.
