SCREW AND BARREL.png


38CrMoAl steel was treated by composite technology of laser hardening and nitriding, and then the microstructure and properties of the composite modified layer were investigated using X-ray diffraction, scanning electron microscopy, electron probe micro-analyzer, Vickers hardness tester, and friction wear testing machine. The results show that the composite modified layer mainly consists of α-Fe, Fe4N, Fe3N, Cr23C6, AlN, and Cr2N phases. Laser hardening can effectively increases the depth of the nitrided layer and distribution uniformity of the nitrides, as a result of grain refinement and high concentration microscopic defects. At the same time, the content of Fe4N in the composite modified layer is higher than that of in the layer treated only by nitriding, where as that of the Fe3N is lower. Compared with individual laser hardening technology and individual nitriding technology, the composite treatment technology can effectively increase the hardness and wear resistance of the 38CrMoAl steel surface.
