From June 26 to 28, 2024, the "Fourth Chemical Heat Treatment Forum" was held in Zhengzhou. Researcher Chen Guomin, former chief engineer of Zhengzhou Machinery Research Institute Co., Ltd., Researcher Tong Xiaodong of Beijing Institute of Aeronautical Materials, Senior Engineer Zhu Baizhi, Director of NGC Industry Association, School of Materials Science and Engineering of Tongji University, and Doctoral Supervisor Gao Yukui, Deputy Director of Shanghai Key Laboratory of Metal Functional Materials Development and Application, and 28 other experts and scholars discussed in depth and gave suggestions and opinions on chemical heat treatment technologies such as carburizing, nitriding, and boriding and technical difficulties in actual work. Our group sent General Manager Zhu Jinkai of the group, Director Shen of Shanghai Pengtai Company, and Engineer Zhang of Wuxi Xinchangtai to attend the meeting and study.

Heat treatment process, laser hardening has the following characteristics

The heating speed is extremely fast, the cooling speed is high, and the deformation of the workpiece is extremely small. Because the laser has a very high power density, the laser beam can make the surface temperature rise at a rate of 104~1060C/s when scanning the surface of the material. The material can be heated to the phase change zone in a very short time, and the cooling rate of the material can reach 105 9C/s. The action time of the laser is also very short, so the modified area is limited to the surface of the workpiece, and it is not easy to cause thermal deformation of the whole workpiece.
