Abstract

Abstract: Effect of subcritical quenching on microstructure, mechanical properties and wear resistance of the NiCrMo-3 surfacing layer was studied. The results show that the grain size of the surfacing layer after subcritical quenching is smaller and flocculent structured which composes of intermetallic compounds as CrO₂ and NiFe₂O₄ on surface and interstitial compounds formed by Ni and Cr elements at substrates. The hardness of the surfacing layer after subcritical quenching is high and shows good wear resistance, the strength increases but the toughness decreases. The friction coefficient of which subcritical water quenched decreases during friction test, and a ductile banded structure between the brittle and hard phases occurs in its tensile fracture.

Key words: subcritical quenching, NiCrMo-3 surfacing layer, microstructure, wear resistance
