ROUGHNESS ANALYSIS ON RUST-REMOVAL SURFACE OF THREE CONSTRUCTION STEELS AFTER CORROSION TEST
|
Abstract:
A roughness analysis of rust-removal surface of three construction steels after varying in-door accelerated cyclic corrosion tests(CCT)had been carried out by using a roughness analyzer in this paper.The steels include a weathering and fire-proof steel WGJ510C2 and two conventional construction steels Q235 and Q345.The results show that there are some dense distributed but shallow pits on the surface of steel WGJ510C2 and some sparsely distributed but deep pits on the surface of steel Q235 and steel Q345 fo...
