铝合金门窗碳素钢五金件在京郊某地不同二氧化硫浓度下的腐蚀速率实验

摘要

本实验通过人工喷涂二氧化硫的方法,改变空气环境,以检测空气中不同二氧化硫浓度对京郊铝合金门窗碳素钢五金件腐蚀速率的影响。%The experiment is carried on at Beijing suburb, which changes the atmosphere entironment by manual spraying SO2 , to test corrupting speed about carbon structural steel hardware of aluminum door window in different thickness of SO2.
