Abstract
Idlers are machine elements which are subjected to friction solicitations. The geometry, dimensions and weight can’t be modified that is why we decided to modify the contact surface by coating. We have chosen the steel type OLC 45 and we coated it with CMoCuNiCrSiBO by thermal deposition. The selection of these materials was made after a detailed study of the literature. After we obtained the samples, we subjected them to qualitative analyses SEM and XRD and to Quantitative analysis – wearing – destructive test where we obtained the friction coefficient between two coated surfaces [1]. We made the samples which we have analyzed by X-Ray Diffraction and we obtained the quality of the coating [2]. The results showed that the new material has a better structure than the basic material, and we can estimate a high durability of the machine elements coated. On friction test we have determined friction coefficient value.
