First, in a primary sintering step, a manufacturing system 1 for a sliding member 2 laminates and thereby forms a sintered alloy layer 4 on back metal 3. Subsequently, a large number of indents 5 are formed on a front surface of the sintered alloy layer 4 by an indent forming mechanism 14. Next, the back metal 3 and sintered alloy layer 4 are rolled by a reduction roll 15 and a secondary sintering process is applied to the sintered alloy layer 4. Consequently, the sliding member 2 is manufactured with the large number of indents 5 provided on a front surface. Since the indents 5 are formed on the sintered alloy layer 4 after the primary sintering step, it is possible to inhibit work hardening from occurring in the indents 5 and surrounding areas.
A manufacturing method for a sliding member made up of a sintered alloy layer laminated on a front surface of back metal with a large number of indents formed on a front surface of the sintered alloy layer, the manufacturing method comprising:
