It is shown that a self-lubricating antifriction composite with microheterogeneous structure is synthesized during sintering of the Cu–Ni–P–MoS2 powder in hydrogen at 900 and 950°C. The structure of the self-lubricating antifriction composite formed at 900°C represents an α-solid solution of nickel in copper hardened by complex phosphide MoNiP, in which sulfide Cu2Mo3S4 is distributed. Molybdenum disulfide interacts with hydrogen at 950°C to form Cu2S and MoP. The structure of the self-lubricating antifriction composite formed at 950°C differs from the previous one in the amount of α-solid solution of nickel in copper, type (MoP) and content of hardening phase in it, and type (Cu2Mo3S4 and Cu2S) and amount of antifriction structural component.
