Improvement of mechanical properties of bevel gears by nitrocarburizing

Abstract The automotive industry is one of the most important consumers materials and especially metal materials. Competition in this area, technical progress vehicle requirements require knowledge properties materials, processing technologies that ensure operating requirements, reliability, aesthetic with minimum costs. This work part modern trends to improve surface layers parts used mainly beyond. A nitrocarburizing study presented on tapered gears make up machine differential, as well optimization technology. paper describes objectives nitrocarburizing, for purpose, ending structures obtained after nitrocarburizing.
