A thermal spray material includes a mixture of 5-30 weight % of an AlSi alloy powder with 95-70 weight percent of a cast iron powder to provide abrasion resistance for aluminum alloy parts. The AlSi alloy powder contains 12-30 weight % Si, at least one element selected from a group consisting of 0.5-5.0 weight % Cu and 0.2-3.0 weight % Mg, 1-15% of at least one element selected from the group consisting of Fe, Mn, and Ni, and a mass balance of Al. The cast iron powder contains 2-4 weight % C, no more than 0.3 weight % Si, and 0.5-3.0 weight % P. A sliding surface of a sliding member is thermal sprayed with a coating of this thermal spray material to provide a sliding member having excellent abrasion resistance.
