Abstract

Wear resistance properties of TiC reinforced Ni thermally sprayed coatings have been investigated. The powder used was nickel coated titanium carbide particles (TiC-15%Ni), size: - 106+45 Jim. The starting powder was characterized via metallography, SEM and X-ray diffraction analysis for identification of its morphology and the phases present. The TiC-15%Ni powder was then deposited on to AISI 1019 carbon steel substrates (60 mm dia. and 10 mm thick wear discs) using an APS (Air-Plasma-Spray) Plasma Technik gun. The plasma gun produced a plasma jet as a result of ionization of Ar/H gas mixture. The
