In plasma spraying process,the splats are building blocks of the whole coating. Thus,studies on the morphology and microstructure of splats are essential to coating process optimization and quality control. In this paper,the effect of substrate temperature( Ts) on the morphologies,grain size and texture of plasma sprayed Ni splats collected on 1Cr13 stainless steel was investigated by scanning electron microscope( SEM) and electron-backscattered diffraction( EBSD),while the thermal contact resistance betwee...
