Development Analysis of Anti-corrosion Process for Guangzhou Metro Mental Fasteners

The paper analyzed various factors in the improvement of anti-corrosion process of metro tablet,original Dacromet technology of metal fasteners has suffered serious corrosion,and is not suit for bad weather of Guangzhou.The paper analyzed corroding reasons of tablet metal fasteners of Guangzhou metro from all aspects,at the same time,as the improving ways,introduced the characters and applications of new type of anti-corrosion technology,finally,the differences f both were presented form test data,real application,customers reactions.The index of new technology can meet the requirements of anti-corrosion and mechanical property of bolts,and can bear the friction of wrench many times,so it fully suit the weather of Guagnzhou.
