【Abstract】 The characteristics of erosion-corrosion in producing wet-process phosphoric acid are analyzed. From the viewpoint of working condition as well as corrosion process, some main anti-corrosion measures for agitating vane made of stainless steel are discussed. It is pointed out that it is very important to control and adjust the residual stress formed in the interface to elevate the interface strength between the coating layer and the metal substrate.更多还原
