To understand the effects of spray parameters on the splashing,cast iron particles were plasma-sprayed onto polished surfaces of aluminum substrate to form single splats.Various plasma arc powers and spray distances were applied to adjust the morphology of the splats which was studied using a field emission scanning electron microscope(FESEM).The experimentalresults showed that the splashing of impinging droplets was significantly restrained for the splats deposited with high arc power(30 k W)and short spray distance(80 mm).This finding would be beneficialto improving the adhesive strength of the coating.
