Abstract

The most important characteristic feature of boronizing is that the boron layer obtained at the surface has a very high hardness, improved wear resistance, and low coefficient of friction. Due to the sudden transition from a very hard surface to a relatively soft core, cracks are likely to occur at the interface. These cracks may lead to spalling, and therefore the advantageous effects of boronizing are limited under heavy loads. In this study, the pitting and wear behavior of spur gear surfaces of AISI 8620 steel treated by carburizing, boronizing, and borocarburizing have been examined.
