Procedure and Test of Arc Spraying Nano Sealing Composite Coating

Authors discussed the procedure of arc spraying nano sealing composite coating,and through a series of tests,such as bond strength test,the neutral salt spray test,test of resistance to heat and humidity,artificial weathering age test,electrochemical performance test and marine corrosive panel test,the systematic comprehensive performance of arc spraying nano sealing composite coating was studied.Results show that arc spraying nano sealing composite coating with high adhesion and high corrosion resistance characteristic,for steel substrate has long life of corrosion resistance protection,and has wide engineering application prospects on steel bridges.
