摘要
用增重法和俄歇能谱(AES)纵向溅射法,对冷轧Pb、Sn及其常量配比的Pb-Sn合金用3种不同腐蚀方法测定和计算了其腐蚀速度。实验证明,Pb在实验室大气腐蚀、155℃干热大气腐蚀和100℃水蒸气腐蚀下的腐蚀速度符合抛物线关系式。同时也证明,Sn和Pb-Sn合金在100℃水蒸气下的腐蚀速度也符合抛物线关系式。并给出了155℃干热腐蚀288h和大气腐蚀2.5年的腐蚀层厚度数据。
The corrosion velocities of the cold-rolling strips of Pb, Sn and their alloys were investigated by the use of methods of the weight increase and AES longitudinal spattering. The parabolic relations of the corrosion velocity for the lead were obtained under the room temperature and atmosphere, of dryheating air 155℃ or water vapor at 100℃. Similar relations for Tin and Pb-Sn alloys were obtained in the atmosphere of watar vapour at 100℃. At the sametime the data on the thickness of the corrosion layers of the alloys and the metals in the dry-heating air at 155℃ for 288 h and in the atmosphere at the room temperature for two and a half years were also obtained.
