Experimental investigations were carried out with a 3.3 kJ Mather-type DPF operating in nitrogen at a low chamber pressure with low carbon steel as the target material. It was found that the DPF ion beam implanted nitrogen onto the steel surface thereby causing a marked increase in surface hardness. The variation of pressure and target distances appear to affect the outcome of this nitriding technique with optimum hardness reached at the pressure setting of 1 Torr and at a target distance of 40 mm from the anode.}, number={6}, journal={Walailak Journal of Science and Technology (WJST)}, author={TEH, Thiam Oun and SINGH, Arwinder and ALI, Jalil and NG, Chee An and NG, Xue Yinn and WONG, Jun Wen and SAW, Sor Heoh and LEE, Sing}, year={2018}, month={Dec.}, pages={379–384} }
