Changzhou Yao Shuo Laser Technology Co., Ltd. is mainly engaged in laser surface treatment technology research and application of enterprises, and providing a metal surface preparation and selection of material and related technical consulting services. We have accumulated a lot of successful experience in the laser surface heat treatment and laser repair aspect, metallurgy, machinery, automobile, petrochemical, power, light industry, mold and other industries to solve the problem of strengthening and repair a number of key components. 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. On the tooth surface of large gears, large shaft journal quenching, the surface roughness is essentially the same, does not require subsequent machining to meet the needs of the actual working conditions. Laser heating surface hardening extremely fast heating rate (105 ~ 106 ℃ / s) laser quenching technology, superheat degree, phase transformation driving force, the number of nuclear surge of austenitic shape, diffusion homogenization come without austenite in different regions of martensite formation temperature inside microscopic carbon and alloy concentration increases unevenness guide laser hardening, microstructure similar regional carbon content austenite becomes smaller, the subsequent rapid cooling (104 ℃ / s) in a large differences produce fine martensite. Due to rapid heating, no diffusion through the pearlite structure into an austenite structure; due to rapid cooling, the austenite structure by free diffusion into martensite, while increasing the amount of retained austenite, the carbon diffusion laser hardening too late, so that supercooled austenite carbon content increases, increasing the carbon content of martensite, hardness. Laser hardening process, increase the surface hardness (certified), laser hardening by Changzhou Changzhou Yao Shuo Laser Technology Co., Changzhou Yao Shuo Laser Technology Co., Ltd. (www.czshuoyao.com) Changzhou, Jiangsu, industrial products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Yao Shuo laser leadership with the staff warmly welcome all inquiries negotiations to create the master Yao laser better future.
