摘要
分别采用溶剂型涂料和水性涂料体系,考察了NORSOK M-501循环腐蚀试验、ASTM B117盐雾试验、ASTM 5894循环腐蚀试验和单独的ASTM 5894盐雾试验对涂层的影响。结果表明,NORSOK M-501循环对底材的腐蚀主要是缝隙腐蚀和物理作用,而ASTM 5894循环主要是物理作用和微酸性条件下的均匀腐蚀。
By use of solventborne coatings and waterborne coatings, the influence of NORSOK M - 501 cyclic corrosion test, ASTM B117 salt spray test, ASTM 5894 cyclic corrosion test and ASTM 5894 salt spray test on coatings have been studied. It is found that corrosion of NORSOK M -501 cyclic corrosion test is contributed to seam corrosion and physical action, but corrosion of ASTM 5894 cyclic corrosion test is based on physical action and uniform corrosion in slightly acid, condition.
