the surface hardening Laser hardening tooth surface

Project leader in metal heat treatment, mechanical design, finite element modeling, analysis, optimization and software development to achieve certain results, with rich experience, currently presided over Zhejiang Provincial Natural Science Foundation 1, in Zhejiang Province science and technology projects 1. The subject of a auspices of end item: Science and Technology Bureau of Jiaxing City, a research, research a Zhejiang Provincial Education Department, horizontal issues 2, Jiaxing College education reform issues and research projects of one. Issues involved in end items are: the National Natural Science Foundation project, the Provincial Natural Science Foundation of three, two horizontal issues, Zhejiang Provincial Education Department issues one, two horizontal issues, Jiaxing University research projects 2. More than 20 papers published research, which included seven EI, ISTP contains three, has authorized the invention patent, utility model patents 3, the software copyright registration 2. The handy use of  laser pointer  is the key point.
Jiaxing University - Zhejiang Valor laser processing technology research and development centers are independently owned large format laser cutting, laser engraving machine, micro-hardness machine, DCL has been flat cutting board, including laser cutting machine such as product development accumulated valuable experience. The experimental equipment and advanced production capabilities, developed in collaboration with the project conditions. Gear is widely used in machinery manufacturing industry parts. In order to improve the carrying capacity of gear is required for surface hardening of gears, while the traditional gear hardening process, such as carburizing, nitriding and other surface chemical treatment and induction surface hardening, flame surface hardening, etc. There are two main problems: the large deformation and heat treatment is not easy to obtain uniform distribution along the tooth profile of the hardened layer, thus affecting the service life of gears. The handy use of  laser pointer  will be shown in details.
Laser hardening is the use of laser surface heating to the material above the phase transition point, as the material itself cooling, austenite into martensite, so that the surface hardening Laser hardening tooth surface, its high rate of heating and cooling, process cycle is short, do not need an external quenching medium. with a small deformation of the workpiece, the working environment clean, such treatment does not require finish grinding, and is not subject to heat treatment processing equipment, gear size restrictions on the size of the unique advantages as early as 1980, the United States Military research at the Applied Technology Laboratory experiments on laser hardening of gears findings made a broadcast report.
