摘要
电解等离子氮化是一种极具吸引力的化学热处理方法，通过氮饱和来改善钢的表面性能。这种方法被广泛应用于各种工作条件下的钢和铁基合金。在这项工作中，利用液相等离子氮化技术，在不同浓度的电解液中，在 40CrNi 钢表面获得了氮化层。我们使用扫描电子显微镜（SEM）和 X 射线衍射（XRD）对氮化层的微观结构和相组成进行了研究和分析，并使用球盘法进行了维氏硬度和耐磨性测试。由于氮化 40CrNi 钢表面形成的 ε-Fe2N 相具有润滑性，因此其显微硬度和耐磨性得到了显著提高。
Surface Modification of Chromium–Nickel Steel by Electrolytic Plasma Nitriding Method
Electrolytic plasma nitriding is an attractive chemical heat treatment used to improve the surface properties of steel by implementing nitrogen saturation. This method is widely applied to steel and iron-based alloys operating under various operating conditions. In this work, using liquid-phase plasma nitriding technology, a nitrided layer was obtained on the surface of 40CrNi steel in electrolytes of different concentrations. The microstructure and phase composition of the nitrided layer were investigated and analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD), and we performed Vickers hardness and wear resistance tests using the ball-on-disc method. The microhardness and wear resistance of nitrided 40CrNi steel were significantly improved due to the lubricating properties of the ε-Fe2N phase formed on its surface.
