Surface Treatments to Improve the Wear Resistance of Type 304 Strainless Steel in Water
Abstract
Various surface treatments were applied to 304 stainless steel journals in an attempt to improve their wear resistance. The treatments consisted of one or more of the following; shot-blasting with Glas-shot or chilled-iron-shot, heating in air, in argon containing air or in vacuum. The treated journals were tested against Waukesha 88 bearings at loads of 20, 40 and 60 lb and speeds of 40 and 180 rev/min, in 80 F pH 7 water. Representative specimens of the various treatments were metallographically examined to determine the nature of the surface. In general, treated journals had much better wear resistance than untreated journals. The improvement was believed to be due mainly to surface oxidation. The best surface treatment consisted of Glas-shot blasting the surface followed by heating in air at 800 C for 21 h.
