Abstract
Because of the difficulty in regulating the process parameters of plasma spray welding, a rapid computational method were investigated to quickly attain the appropriate parameters, such as transferred arc current, spray welding speed, and powder feeding rate, and a process parameter combination of plasma spray welding could be easily acquired. To verify this rapid computational method, a process experiment was designed that the Ni60a alloy powders were sprayed on Q235 substrates by plasma spray welding in different coating thickness. The experimental result suggests that, the spraying layer can be obtained by using the process parameters calculated by this computational method, showing good adhesion with substrates and high surface hardness, the minimum and maximum hardness of coating surface is Hv 730 and Hv 804, respectively.关键词
