This paper presents a way that combines in-situ synthesis of reinforcement particulates by SHS with V-EPC infiltration technique to make TiB_2 particulates reinforced 45 steel matrix surface composites. Firstly, alloy powders mixed with certain amounts of binder and lacquer solvent, and then the powers were pressed as a 30mm diameter×5mm thickness preform in a mold with a pressure of 40MPa. When the preform is dried, it was attached on a surface of EPS template, then painted a layer of anti-sand burning coa...
