This work presents the investigation of a boriding process on two grades stainless steel namely UNS32750 super duplex and UNSS31803 in order to improve material properties possibly reduce catastrophic failure industrial components. Usage steels has become customary fields oil refinery, marine pipeline applications due increased corrosion resistance; however, these materials exhibit low wear cha...
