THE use of porous-chromium-plated rings in aircraft engines has improved the performance and increased the number of hours between overhauling.Mr. Jarrett presents data showing the effect of temperature upon the decrease in hardness of the chromium plate. The time and temperature data on the chromium plate indicate that the decrease in hardness occurs in a very short interval of time, particularly at temperatures around 700 F.Actual field tests show that ring life is increased and barrel wear reduced when using porous-chromium-plated rings in the top groove of each piston.
