Effects of Alloy Powder for WC/Steel Base Surface Composite Structure and Interface
Use Cr15 high chrome steel as base, WC particles as reinforcing particles, and adopting casting-infiltration method, a kind of quite steel-base surface wear-resistant material was prepared. The effect of Alloy powder for WC/steel base surface composite structure and interface was tested by OM, SEM and EDS. The results showed that after adding nickel powder into the composite layer, martensite, austenite, pearlite and eutectic carbide distributed in the matrix; after adding tungsten iron powder into the composite layer, more martensite distributed in the matrix; after adding molybdenum iron powder into the composite layer, martensite, austenite, pearlite and carbide distributed in the matrix. If the base material was high chrome (Cr15) and adds molybdenum iron powder in the composite layer, composite layer interface transition is good, more WC particles and irregular small carbide particles in composite layer.
