发明名称 ELECTROTINNING PROCESS
摘要 In the process of reducing oxidation in stannous tin plating baths, particularly halogen tin baths, by sparging the bath with an inert gas such as nitrogen to displace dissolved and entrained oxygen, deposition of salt at the sparger outlets is minimized or avoided by the improvement of introducing water into the inert gas stream.
