Abstract:
This paper will systematically study the different shapes of steels corrosion rate under different corrosion environments through accelerated corrosion test of orthogonal experiment and the corresponding physical tests and electrochemical detection methods. The experimental results show that the corrosion resistance of the deformed bar is poorer than the plain round bar. In the same corrosive environment, its tensile strength, yield strength and elongation decline are more significantly than the round steel, and the change of the elongation is more obvious. Experimental results also show that in the environment which is absence of chloride ion, reinforced is basically with uniform corrosion in previous time, late stage for the development of local corrosion, the mechanics performance index is also present a corresponding positive correlation with the corrosion situation. But the uneven corrosion condition appears at the previous period when it is in the chlorine ion environment. In this condition, the mechanical performance and corrosion situation is no longer in linear relationship, but the trend of rapidly decline. Results of weightlessness rate test confirm that the correlation of degree of corrosion and the mechanical properties.
