Corrosion resistance of 2195 aluminum alloy treated by multi-step-heating-rate controlled process XU Yue(许 越), LIU Yu-feng(刘玉峰), GENG Ji-ping(耿季平) School of Materials Science and Engineering... to prolong its service life, a multi-step-heating-rate(MSRC) process was carried out. Investigations were carried out to find the effect of the MSRC process on the alloys corrosion resistance. It is found......
A Controlled New Process of Pack Aluminization XU Hong1,LI Pei-ning1,HUANG Zhi-rong1,MA Liu-bao1 (1.School of Mechanical Engineering, East China University of Science and Technology, Shanghai, China) 摘要:Aluminum diffusion coatings are often prepared by a pack aluminization technique, which is a specific variety of chemical vapor deposition (CVD) method. The coating process takes place in a bed......
and the backside weld appearance. It can be seen that full penetration and good quality of weld are ensured during the controlled pulse key-holing PAW process. Fig.7 PAW control experiment results... the penetration extent of PAW process. 3) Through employing the controlled pulse key-holing strategy, keyhole PAW process control is realized. And the PAW process is stable and satisfactory weld formation......
