cBN –TiC and WC –Co Composites: Optimization of Co‐Extruding Conditions
Source abstract
Abstract
In this study, double‐layer tubes with inner‐layer cubic boron nitride–titanium carbide ( cBN –TiC) and outer‐layer tungsten carbide–cobalt ( WC –Co) were fabricated by co‐extrusion. The Taguchi method was used to determine the optimal parameters, including extrusion ratio, half‐die angle, extrusion speed, and binder amount. The double‐layer tube made using these optimal parameters had an inner‐layer hardness of 3825 Hv and an outer‐layer hardness of 1849 Hv. The porosity of the double‐layer tube was 10.4%. Furthermore, the crystalline structures obtained from the inner and outer layers were cBN , TiC, TiB 2 , and BN i and WC and Co 2 C phases.
