Abstract

Abstract The present investigation deals with the fabrication of a novel thermally sprayed coating from a diamond reinforced nano-structured bronze feedstock. Bronze powders were ball-milled with 10 wt% mono-crystalline diamond particles producing a micro-sized powder feedstock. The ball milled powder was agglomerated to prepare the thermal spray feedstock. Both milled and as-received powders were deposited on steel substrates using high velocity oxy-fuel spraying to produce coatings with thickness in the range of 150–200 μm. The coatings were characterized for microstructure, phases, hardness, elastic modulus and residual stress. Raman imaging of the coating revealed that diamond was retained in the coating after thermal spraying. Micro-hardness and elastic modulus of coatings improved with diamond reinforcement.
