Abstract

Boriding is one of the chemical method to increase surface hardness as well as carburizing, and nitriding. Gas boriding and boron paste boriding methods were investigated to replace salt bath boriding. Boron paste boriding method is selected due to safety, small waste and low cost. And then boriding is also carried out micro-pulsed PECVD in order to increase efficiency of boriding. Mechanical properties, microstructure, surface concentration, and depth profile of borided layer is investigated by micro-vickers hardness tester, SEM, XRD, and AES.
