Raw materials were powders of chromium oxide (Cr2O3) with a size range comprised between 16 and 42 µm and stainless steel (Iron base with 17 wt % of Cr and 12 wt % of Ni) with the particle size between 22 and 53 µm. Both powders were simultaneously injected with two separated injectors in a direct current (DC) plasma jet at atmospheric pressure (APS).The influence of various percentages of stainless steel in chromium oxide has been studied on deposit micro-structural and tribology properties. All coatings showed a lamellar structure with a random distribution of both materials. The stainless steel percentage effect on the microstructure of the deposit has been studied by scanning electronic microscopy (SEM) and has showed that rising the stainless steel percentage increases the coating cohesion.
