摘要: Purpose – Thick composite claddings of carbides on a metal matrix are ideal for use in components that subject to severe abrasive wear. It is (MMC) reinforced by an appropriate ceramic phase and nano-diamond cladding reduce friction protect the opposing surface. The paper aims discuss these issues. Design/methodology/approach This work evaluated wear performance carbon steel cladded with TiC/nano-diamond powders gas tungsten arc welding (GTAW) method. microstructures, chemical compositions, characteristics surfaces were analyzed scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX). Findings was uniform, continuous, almost defect-free, particles evenly distributed throughout layer. results test indicate coefficient TiC+1.5% lower than AISI 1020 steel. Thus, scar ar...
