Abstract

Gears have the role of force and torque transmition by friction. They are subjected in operating to fatigue and bending, this being the reason of the pitting type wear appearance. The geometry, dimensions and weight can’t be modificated that is why we decided to modify the contact surface by coating. We have chosen the steel type 16MnCr5 and we coated it with Mo. The selection of the materials was made after a detailed study of the literature. After we obtained the samples, we subjected them to bending tests to determine the mechanical properties. On the SEM analysis we obtained the quality of the coatings. The results showed how the coating influences the properties of the basic material.
