Abstract

In the present work, Ni based powder was deposited on stainless steel substrate using a low velocity flame spray technique. The coating of thickness 300 μm was developed using a neutral oxy-acetylene flame. To enhance the microstructure and wear resistance, the coated specimens were heat treated and cooled using various cooling strategies, such as, air, water, and furnace cooling. The microstructure of the as-sprayed and heat treated specimens were studied using SEM. Some unmelted particles and pores were also present in the as-sprayed specimen. The watercooled specimen exhibits equiaxed structure, while the furnace cooled coating demonstrates a coarse structure. The microhardness of the specimens was evaluated using a Vicker's microhardness tester. The water-cooled specimen exhibits highest hardness and wear resistance.
