摘要： A self-lubricating sintered sliding member and its producing method, the member having excellent seizing resistance and wear resistance even in offset load and high load applications.The self-lubricating sintered sliding member is composed of an iron-family metal substrate and a sintered contact layer that is formed on a sliding side of the iron-family metal substrate and made from a sintered contact material containing an iron-family material. The sintered contact layer has, on a surface thereof, protrusions formed from solid lubricant particles including graphite. A solid lubricant layer is laid over the surface of the sintered contact layer where the protrusions are formed.
