Flank Wear Mechanism of WC-5TiC-10Co Cemented Carbides Inserts when Machining HT250 Gray Cast Iron

Abstract:

WC–5TiC–10Co cemented carbides inserts were prepared and used for the cutting tool for HT250 gray cast iron. The objective was to investigate the wear mechanism when machining HT250 gray cast iron with WC–5TiC–10Co cemented carbides inserts. WC–10Co cemented carbides with the same sintering technology and grain size were prepared for comparison. wear mechanism was examined at the same cutting parameters. The cutting tests were performed at a speed of 120 m/min with feed rate of 0.2 mm/rev and a constant depth of cut of 0.2 mm under dry conditions. Tool wear mechanism is analyzed by SEM and EDS. Adhesive and built-up-edge were found to be the predominant tool wear for WC–5TiC–10Co cemented carbides inserts. However, Attrition was the main wear mechanisms observed in WC–10Co cutting tools. The results obtained indicated that WC–5TiC–10Co cutting tools performed better than WC–10Co cutting tools, in terms of tool wear with current parameters.
