微量Ti对Sn-9Zn-xTi无铅焊料耐蚀性的影响
Effect of trace Ti on corrosion resistance of lead-free Sn-9Zn-xTi solder
摘要
Abstract
The poor corrosion resistance of Sn-Zn lead-free solder are important factors hindering its application.In this paper,by adding trace amounts of Ti to Sn-9Zn eutectic alloys (mass fractions=0,0.01％,0.03％,0.05％,0.1％),the potential dynamic polarization curves (I/E) and electrochemical impedance spectroscopy (EIS) of Sn-9Zn-xTi alloys in 3.5％ (mass fraction) NaCl solution were measured.The surface appearance of the alloy was observed by scanning electron microscopy (SEM).The corrosion resistance of the alloy under different immersion time was studied.It is found that trace Ti element can improve the corrosion resistance of Sn-9Zn,and 0.05％ Ti (mass fraction) content is the most suitable.关键词
