Abstract
PURPOSE: To provide a member of the moving valve mechanism of an internal combustion engine with superior wear resistance by forming the contact surface of a rocker arm or a valve lifter contacting slidably with a cam with a sintered Fe alloy contg. Cr, W, C and P and/or B.
CONSTITUTION: The contact surface of a rocker arm 1 or a valve lifter 3 requiring high wear resistance for slidable contact with a cam 2 among the constitution members of the moving valve mechanism of an internal combustion engine is formed with a sintered Fe alloy having a composition consisting of 2W7% Cr, 0.5W4% W, 0.5W3% C, 0.1W2% P and/or B and the balance Fe with inevitable impurities. The use of this alloy reduces remarkably the wear of each of the cam and an opposite member contacting slidably with the cam and the total wear of them, so the life of the moving valve mechanism can be elongated.
