A finite element model for analyzing the strain-stress field of laser cladding process was built and the process with powder feeding was analyzed with the model. Temperature variation during cladding described in Part I was applied as “body force” loads in the strain-stress analysis. The analysis result shows that, by the end of cladding, the(More)
Laser cladding consists of covering a substrate surface with a coating of a different nature. As a complex thermal-mechanical process, laser cladding is not quite understood yet. In this study, a finite element model for analyzing the temperature field was built and the laser cladding process with powder feeding was analyzed with the model. The analysis(More)
a sequencing batch reactor (SBR) was used to treat synthetic wastewater when dissolved oxygen (DO) concentration and temperature were 0.5-1.0mg/L, and 30±1¿ respectively. Effect of COD/NH4+-N and influent pH on simultaneous nitrification and denitrification (SND) were investigated. The results indicated that removal efficiencies of ammonia nitrogen(More)
