Brass is one of the important basic materials for industrial products.The improvement of its salt corrosion resistance has been widely concerned by industry and scientific research in recent years.In this study,a method of preparing salt resistant coatings for brass was proposed.Firstly,the super hydrophobic surface of brass with micro nano texture was induced by nanosecond laser and modified with fluorosilane to enhance its stability.Then,silicone oil was injected into the super hydrophobic matrix to obtain smooth super hydrophobic coating surface.Finally,the sample was immersed in 3.5wt.% NaCl solution for PDP and EIS tests,the results show that smooth surface is better than ordinary super hydrophobic surface salt corrosion performance,better than the original brass surface.This study can play a certain role in promoting the development of metal anticorrosive coatings,which is of great significance to the laser induced preparation of smooth super hydrophobic surface,and provides a convenient and effective means for metal corrosion prevention in the industrial field.
