Metal material change occurs in the laser irradiation. Metallic material under laser irradiation ultra-fast heating phase transition and rapid fusing characteristics. Laser heating phase transition completion time is very short laser hardening process, while a large temperature gradient heating zone laser hardening, which in the case of a metallic material redistribution carbide dissolution and dissolved in austenite diffusion of carbon and alloy elements, in between different parts of the laser heating zone is very different laser quenching hardness, that lead to non-uniformity of austenitic components. Laser rapid heating phase transition phase transition caused a great degree of superheat the driving force is large, so the number of nuclei formed austenite increase laser quenching technology, short time to complete the phase change also makes the phase deformed nuclei of critical radius is small, either In the original boundaries of the sub-grain boundary nucleation, nucleation phase can also interface to other crystal defects. Yao Shuo laser has a professional team of laser surface treatment, over the years accumulated a wealth of experience in the laser surface treatment technology design and other aspects of the construction process. In accordance with the depth of laser hardened layer parts component size and shape as well as the different laser parameters, generally between 0.3 ~ 2.0mm range. Rail laser hardening, laser hardening Changzhou, Shuo Yao Yao Shuo laser provided by Changzhou Laser Technology Limited. Changzhou Yao Shuo Laser Technology Co., Ltd.
