摘　　要：通过赫尔槽试验、扫描电镜(SEM)分析、中性盐雾试验、重铬酸钾法COD(化学需氧量)检测,考察了苯酚磺酸(PSA)体系和甲基磺酸(MSA)体系镀锡液在镀层晶粒结构、耐蚀性以及槽电压、COD等方面存在的差异。结果表明:MSA镀锡时槽电压更低,镀液COD是PSA镀液的1/20,所得产品的晶粒结构更致密,耐蚀性更好。The differences of PSA （phenolsulfonic acid） and MSA （methanesulfonic acid） tinning baths in grain structure and corrosion resistance of deposit, tank voltage, and COD （chemical oxygen demand） were studied by Hull cell test, scanning electron microscopy （SEM）, neutral salt spray test, and COD determination by potassium dichromate method. The results showed that the MSA bath features lower tinning voltage, and produces the deposits with more compact grain structure and better corrosion resistance. The COD of MSA bath is only 1/20 of that of the PSA bath.
