Abstract
An electron beam cladding method utilizing an automatic powder feeder under vacuum conditions was developed and the layer formation characteristics we re investigated using Ni-based self-fluxing alloy (SFA) powder under variou s electron beam conditions. The properties of cladding layers were examined by the Vickers hardness test, a sand erosion test and a corrosion test. Ba sed on the test results, a uniform Cr3C2/Ni-Cr alloy layer was successfully formed on mild-steel plate. The layer displayed a high hardness of 791 HV as well as high erosion and corrosion resistance. (C) 2001 Elsevier Science Ltd. All rights reserved.
