激光表面改性石墨与DT4C异质钎焊研究
Laser Surface Modification Assisted Joining of Graphite and DT4C Pure Iron
摘要
Abstract
In order to solve the heat dissipation of the magnetic coil,the electrical pure iron should be joined to graphite.And this component should have excellent high and low temperature cycle stability.To improve the thermal shock resistance,the graphite is perforated by laser in this paper.And then the dissimilar joint of graphite and electrical pure iron is obtained via AgCuTi filler alloy at the brazing temperature of 870°C for 10 min.The joint strength is studied with the different micro-structure on the graphite surface.Meanwhile,the joint strengthening mechanism is analyzed in this paper.关键词
