Summary:
A fatigue machine was rebuilt to investigate the wear of mild steel and AISI Type 304 stainless steel while undergoing cyclic relative motions in air and sea water environments. Wear curves were obtained for both materials by measuring specimen weight loss as a function of the number of cycles of relative motion, and surface damage of the specimens was photographed. The results indicate that a sea water environment has a strong influence upon the wear characteristics of mild steel and 304 stainless steel. For the mild steel, the corrosive effects of the sea water contributed to severe pitting and cracking of the wear surface and resulted in a significant increase in wear; after approximately 2.5 million cycles the amount of wear in sea water was approximately three times that in air. For the stainless steel, the sea water acted primarily as a lubricant and coolant, and served to reduce the amount of wear after 2.5 million cycles to about one-tenth of that in air.
