0前言现场暴露试验是研究海洋大气环境下涂层腐蚀最直接、最可靠的方法,能较为真实地反映涂层与环境的相互作用,但是试验周期过长。为了缩短试验时间、提高效率,而采用了加速腐蚀的方法。最早用于涂层耐蚀性研究的加速腐蚀试验是连续盐雾试验,早在1939年就被作为一项试验标准(A 0 INTRODUCTION Field exposure test is the most direct and reliable method to study coating corrosion in marine atmosphere. It can more accurately reflect the interaction between coating and environment, but the test period is too long. In order to shorten the test time, improve efficiency, and used to accelerate the corrosion method. The earliest accelerated corrosion test used in the study of coating corrosion resistance was a continuous salt spray test as early as 1939 as a test standard (A
