Abstract
It discussed repairing the worn engine crankshaft with chromium series metal powder-cored wire. The Mo, Mn, V, Ti metal powder and the SiC ultrafine particles, WC nanopowder added in chromium series metal powder-cored wire. That made the surfacing layer obtained high bonding strength, high hardness, and obtained high fracture toughness. The result indicated the SiC ultrafine particles/WC nanopowder could promotion the in-situ reaction in the surfacing layer, formed the dissemination strengthening, the melting strengthening and so on multi-mechanism strengthening effect. SiC and the metal matrix was not merely the mechanical bond, the partial regions were by the chemical bond. That realized in the structure continuity. And the repaired crankshaft surface wear-resisting disposition enhanced 24% than the original.
