To solve such problems that a bearing alloy layer may separate from a steel plate during use because of insufficient bonding strength between the steel plate and the bearing alloy layer in a multi-layer sliding member obtained by a conventional sintering method, and that the conventional sintering method requires much time because a pressing process is necessary to crush a porous portion inside the bearing alloy layer after sintering the bearing alloy powder on the steel plate and thereafter a third sintering process has to be performed to spread and adhere the crushed portion.
After the bearing alloy powder is dispersed on the steel plate, the bearing alloy power is adhered in a half-molten state, by being heated at a temperature higher than the solidus-line temperature of the bearing alloy powder and lower than the liquidus-line temperature of the same. Accordingly, in the half-molten bonding of the invention, since the bonding strength between the steel plate and the bearing alloy layer is greatly increased, the bearing alloy layer does not separate from the steel plate even when the multi-layer sliding member is used for a portion like a swash plate used under a severe condition. Further, because the third sintering process and the pressing process are not required as in the sintering method, the number of steps can be reduced.
