Abstract

PURPOSE: To improve the abrasion and the starting torque performance by jointing the surface member of thin Al board or Al alloy to the base member of fine crystal particle superplastic metal then forming an alumina oxide layer on the pressed receiving face.
CONSTITUTION: Fine crystal particle super-plastic metal such as Al alloy containing approximately 22% of Zn is employed as the base matrial, then a surface member 12 of thin Al board different from the base material 11 is jointed to one end and formed to a pillar to produce an intermediate material 1b. Then the intermediate material 1b is inserted into a molding section 44 to form a receiving face 13 in the surface member 12, and pressed by a punch 5 to the size and the shape of a supporting member 1. Thereafter a porous alumina oxide layer is formed through alumite processing on the surface of the receiving face 13 of a completed supporting member 1 and a lubricating member is impregnated.
