What types of test methods are commonly used to detect the corrosion resistance of coatings?

       1) Use environmental test



     Observe and evaluate the corrosion resistance of the coating during the working process of the actual use environment of the sprayed workpiece.

     2) Atmospheric exposure (ie indoor and outdoor exposure) corrosion test

     Put the sprayed workpiece or sample on the sample holder exposed to the atmosphere (indoor or outdoor), conduct corrosion tests under various natural atmospheric conditions, regularly observe the characteristics of the corrosion process, and measure the corrosion rate, so as to evaluate the corrosion resistance of the coating. sex.

     3) Artificial acceleration and simulated corrosion test

     Artificial methods are used to simulate certain corrosive environments, and a rapid corrosion test is carried out on the sprayed workpiece to identify the corrosion resistance of the coating in a fast and effective way.
