Production and Investigation of Ceramic-Metal Composite from Electroless Ni Plated WC and WC-Ti Powders

Abstract
Ni-Ti metal matrix composites reinforced with WC have been fabricated by Tube furnace sintering at various temperatures. A uniform nickel layer on %50Ni,%46.66WC and %3.33Ti powders was deposited prior to sintering using electroless plating technique, allowing closer surface contact than can be achieved using conventional methods such as mechanical alloying. A composite consisting of quaternary additions, a ceramic phase, WC, within a matrix of WCNi,NiTi has been prepared at the temperature range 1000�C-1400�C under Ar shroud. X-Ray diffraction, SEM (Scanning Electron Microscope) density and hardness measurements were employed to characterize the properties of the specimens. Experimental results carried out for 1400�C suggest that the best properties as comprehension strength σmax and hardness 429,1(HV) were obtained at 1400�C and the tube furnace sintering of electroless %50Ni,%46.66WC and %3.33Ti powders is a promising technique to produce ceramic reinforced Ni-WC-Ti composites..
