Název v původním jazyce

Influence of the metallic matrix ratio on the wear resistance (dry and slurry abrasion) of plasma sprayed cermet (chromia / stainless steel) coatings

Popis výsledku v původním jazyce

The work is related to the manufacturing and tribological testing of plasma sprayed cermet coatings of chromium oxide and stainless steel in order to obtain wear resistant coatings to dry and slurry abrasion. Raw materials were fused and crushed powdersof chromium oxide (Cr2O3) and gas atomized stainless steel (iron base with 17 wt. % of Cr and 12 wt. % of Ni). Both powders were simultaneously injected with two separated injectors in a DC plasma jet at atmospheric pressure (APS). The influence, on thecoating microstructural and tribological properties, of various stainless steel weight percentages in chromium oxide has been studied. All coatings exhibited a lamellar structure with a random distribution of the two materials. The effect of the percentage of stainless steel on the microstructure of the coating, studied by scanning electron microscopy, has shown that increasing the stainless steel percentage increased the coating cohesion.
