PURPOSE:To mold the specified formed cam part having an abrasion resisting alloy layer on its surface, by constituting a cam sliding part in a way of sintering a pad member made of kneading abrasive resisting alloy powder and an abrasive. CONSTITUTION:Abrasive resisting alloy powder and acrylic system adhesive are kneaded, forming a sheet, and a pad member 5 provided with a through hole 6 is installed in this sheet, while a cam base member 1 forming an interconnecting hole 3 in the specified position of a cam part 1a is prepared for, then the pad member 5 is applied to the cam base member 1 and simultaneously a pin-form perforated member 4 is inserted into the through hole 6 of the pad member 5 and insertedly locked to the interconnecting hole 3 of the cam base member 1 and, after this perforated member is heated for more than five minutes long at a temperature of 150-380 deg.C in a nonxidating ambience, it is heated and sintered, thus an abrasive resisting sintered layer is formed on the cam part, whereby an oil passage is formable owing to the perforated member. |
