Abstract
WC-Co/Ni-base self-fluxing alloy layers were successfully formed on steel s ubstrates using an electron beam cladding process. The WC particles were de nsely and homogenously dispersed within the Ni-base self-fluxing alloy with out porosities. The effect of the electron beam conditions on layer formati on was investigated, and the cladding layer properties were examined by har dness tests, abrasive wear tests and immersion corrosion tests. It was foun d that the cladding layers showed higher hardness, abrasion resistance and corrosion resistance compared with the mild steel substrate. (C) 2000 Elsev ier Science Ltd. All rights reserved.
