试样随着盐雾腐蚀时间的增长,其总体的抗拉强度出现明显下降。在腐蚀时间达到96小时,其抗拉强度降低近50%,而到240小时其抗拉强度下降近75%。在前24小时试样的抗拉强度下降极为明显,说明在前24小时试样的腐蚀比较迅速,导致拉伸强度下降明显。24小时过后拉伸强度下降趋势明显下降。
With the increase of the salt spray corrosion time, the overall tensile strength of the sample decreased significantly. When the corrosion time reaches 96 hours, its tensile strength is reduced by nearly 50%, and by 240 hours, its tensile strength is reduced by nearly 75%. In the first 24 hours, the tensile strength of the sample has dropped extremely significantly, indicating that the corrosion of the sample in the first 24 hours is relatively rapid, resulting in a significant drop in tensile strength. After 24 hours, the tensile strength declined significantly.
