钢的表面硬化是通过使用大气压等离子体进行氮化来实现的。如果将氢气添加到周围的氮气气氛中，则将脉冲电弧氮气等离子射流喷射到钢表面上会产生扩散层和化合物层。对于直径20mm的圆盘样品，距喷射中心距离较远的地方，硬化层的厚度较薄，但可对整个表面进行硬化。
Surface hardening of steel has been achieved by nitriding using an atmospheric-pressure plasma. Spraying the pulsed-arc nitrogen plasma jet onto a steel surface produces the diffusion layer and the compound layer, provided that hydrogen gas is added to the ambient nitrogen atmosphere. The entire surface of a disk sample of 20mm in diameter can be hardened although the thickness of the hardened layer is less where the distance from the center of jet spraying is larger.
