摘要

研究了 VKS-10 (13Kh3N3M2VFB-Sh) 钢在热处理和热化学处理（即有表面熔融和无表面熔融的激光处理以及随后的真空渗氮）下表面层的形成特点。研究了初步激光处理对表面氮饱和动力学的影响。结果表明，与表面熔化处理相比，表面未熔化的初步激光处理和随后的氮化处理能在 VKS-10 钢上形成更厚的有效氮化层，并提高表面的耐磨性。

Vacuum Nitriding of Heat-Resistant Steel After Laser Processing

Features of formation of surface layers in steel VKS-10 (13Kh3N3M2VFB-Sh) under thermal and thermochemical treatments, i.e., laser processing with and without surface fusion and subsequent vacuum nitriding, are considered. The effect of preliminary laser treatment on the kinetics of saturation of the surface with nitrogen is studied. It is shown that the preliminary laser treatment without fusion of the surface followed by nitriding provides a higher effective thickness of the layer on steel VKS-10 and higher wear resistance of the surface than the treatment with fusion.
