Sažetak
This paper presents research of the solid particle erosion at low particle speeds and various impact angles of conventionally and duplex treated vanadium carbide (VC) coatings produced on the C45E steel substrate by the thermo-reactive diffusion (TRD) technique. The experimental results were obtained from a central composite design (CCD) and statistically analyzed by response surface method (RSM). It was established that speed of the samples is a more significant factor, while the impact angle of the abrasive particles has less effect on the wear process. The results also indicated that the interaction of the samples speed and the impact angle does not have statistically significant effect on the wear process. The mathematical model of the investigated wear process was derived as well.
