The milled powders were plasma-sprayed onto aluminum and stainless steel substrates to obtain Al matrix composites with high SiC weight fraction. The microstructure characteristics of the sprayed composites were investigated by metal microscopy. Surface roughness, coating thickness and microhardness were measured. Microhardness values increased when the amount of SiC particles in Al-12Si coatings increased. The wear behavior of the coatings under dry-sliding and water-lubricated sliding with stainless steel counter material was studied using ball on disc for 10kN. Wear surfaces were investigated with scanning electron microscopy (SEM). Increasing SiC content of coatings increased the wear resistance. The highest wear resistance in coatings was observed in the coating having 50% SiC.EnglishAluminaAluminumBall millingBall millsComposite coatingsLubricationMartensitic stainless steelMicrohardnessPhotoresistsPlasma jetsPlasma sprayingPlasmasPowder metalsProtective coatingsScanning electron microscopySilicon carbideSpheresStainless steelSurface roughnessSurface treatmentThickness measurementWear resistanceAl matrix compositesAlumina ballsAluminium matrix compositesBall-milledCoating thicknessCounter materialsMicrostructure characteristicsMilled powdersPlasma spray coatingRotating ballsSEMSiC particlesStainless steel substratesWater lubricationWear behaviorsWear surfaceWeight fractionsSprayed coatingsArticle10.1080/10426910902941611
