| Abstract: | WC particle surface reinforced steel composite was investigated by using self-made additive under the conditions of dry sand mould hardened by aqueous silicate sodium, the whole procedure was done in atmospheric pressure environment without any vacuum. The abrasive wear resistance of new developed composite is 3.3 times as large as high chromium white cast iron. The hardness is over 60HRC.The surface roughness is small and dimensional precision is high. The thickness of composite layer can be up to 8 mm with equally distribution in all composite layer. The composite layer also binds very well with substrate material. |
