Evaluation of the anticorrosive behavior of epoxy-Nb2O5 paint in high temperatures submitted to the environment with sulfuric acid
The aim of the present work is to evaluate the corrosion resistance of epoxy-Nb 2 O 5 paint in acid atmosphere and high temperatures. For comparison, samples of SAE1020 carbon steel were coated with an epoxy-Nb 2 O 5 paint and an epoxy commercial paint. The samples were partially immersed for 720 h...
