THE USE OF ELECTROLESS COATING IN THE PRODUCTION OF HIGH CERAMIC-TO-METAL RATIO COMPOSITES USING WC POWDER

In this study, the production of high ceramic-to-metal ratio composite using tungsten carbide (WC) powders plated with Nickel (Ni) by electroless method was attempted by means of transient liquid phase sintering. Microstructural characterization in specimens before and after sintering process have been carried out using Scanning Electron Microscope (SEM) and DTA-TG and XRD techniques and microhardness measurements for various processing conditions. Results showed that WC powders can be successfully Ni plated by electroless plating method and optimal condition for the production of high ceramic-to-metal ratio composite is found to be 1150 ˚C in both air and Ar protected furnace conditions.
