Research on Laser Cladded Nickel Based Nanometer Tungsten Carbide Composite Coating DAI Jian-qiang1,ZOU Chang-gu1,YAN Min-jie1,XI Wen-long1,ZHANG Guang-jun1,GE Da-fang1,WANG Hui-Ping1 (1.Shanghai University of Engineering Science, Shanghai, China) 摘要:CO2 laser is adopted on the surface of austenitic stainless steel (1Cr18Ni9) to clad nickel based nanometer WC/Co composite coating. SEM, EDAX......
Numerical simulation of temperature field during selective laser sintering of polymer-coated molybdenum powder BAI Pei-kang(白培康), CHENG Jun(程 军), LIU Bin(刘 斌), WANG Wen-feng(王文峰... laser sintering was introduced. Based on the research of laser heating property, powder thermal physics parameters and laser sintering process, a numerical model of the temperature field during length......
The Ductile to Brittle Transition Behavior of the Modified 9Cr-1Mo Steel and Its Laser Welds R.K.Shiue1,C.Chen2,H.C.Wu2 (1.Department of Materials Science and Engineering, Dong Hwa University... steel and its laser welds was studied. The increase in grain size of the weld structure ascended the DBTT of the steel significantly. The transformation of retained austenite at martensite interlath......
