Abstract
Piston ring wear studies using an automotive engine and a radioactive wear measurement technique are presented to show the effects of compression ring face metallurgy and general lubricant composition on corrosive wear control. These results are correlated with those obtained in a single-cylinder laboratory engine. Results show that lubricant com-position is not critical respecting corrosion when chromium plated and molybdenum-filled compression rings are used, but is critical when plain cast iron rings are used. Although wear for the molybdenum rings may be slightly higher than that for chromium rings, no service problems are anticipated.
