Investigation of Y2O3 Particle Doped on Superalloy by Laser Irradiation孟庆林,邹宇超,徐万仁,何永峰,战效文,国玉军摘 要:<正> Possibility to dope Y2O3 particles into the sur-face of superalloy sample by means of laserirradiation and the relationship betweenhomogeneity and laser irradiation parameters havebeen investigated.The results show that homoge-neous distribution......
FORMATION OF Fe-N COMPOUNDS BY LASER NITRIDATION IN AN ATMOSPHERIC AMBIENT Y.L.Yang1,D.Zhang1,F.J.Sun1 (1.College of Science, Northeastern University, Shenyang 110004, China) Abstract:The formation of Fe-N compounds by laser nitriding in an atmospheric ambient wasreported. By CW-CO2 laser irradiation on pure ferrite iron in the atmospheric am-bient, Fe-N compounds (including Fe2N, Fe3N......
as a mathematical way. ROZZI et al [13-14] investigated a thermal reaction for the irradiation of CO2 laser to rotate a workpiece using a three-dimensional thermal transfer analysis. AHN and LEE [15... energy of this workpiece is transferred to the surface of the workpiece by the irradiation of laser beams and the equation of heat transfer can be defined as  ......
