- Abstract:
- Gears tooth are subjected to fatigue and bending. In operating, on the tooth flanks gears appears a wear type pitting. The geometry, can’t be modificated that is why we decided to modify the contact surface by thermal deposition of an addition material. We made a detailed study of the literature and we decided to use an usual steel which we coated with powder by electro spark process. We have chosen the OLC 45 steel and we coated it with WC. After we obtained the samples, we subjected them to bending tests in order to determine the bending stress and the elasticity modulus. On SEM analysis we obtained the image and the quality of the coatings. The results showed how the coating increases the properties of the basic material.
