| Abstract | A urethane coating is proposed as a method to extend corrosion-fatigue durability of a suction roll KCR 171 duplex stainless steel alloy in white water environment. Rotating fatigue specimens with and without coating were tested in air and in white water to produce SN curves. The results clearly show the improved durability of the coated samples especially in the high-cycle regime. The improvement is more pronounced at low (6 Hz) than at higher (20 Hz) frequencies because the uncoated samples are more affected by the corrosive environment in low frequency testing. Other factors such as surface finish and white water temperature were found to have minor influence. The concept of a protective polymeric coating for suction rolls seems attractive but additional factors such as wear resistance, permeability and adhesion need further investigation. |
