The effects of load, frequency, slip amplitude, humidity and film thickness of polyvinyl chloride on fretting corrosion

Rorrer, Ronald Alvin Lee January 1985 (has links)
The purpose of this study was to investigate the effects and interactions of lead, frequency, amplitude of slip, humidity, and film thickness of polyvinyl chloride on fretting corrosion. In particular, this study describes the effects of these parameters on the polymer film life and also on the wear of the metal surfaces after metallic contact had occurred. The two levels that were used for each parameter are: load, 15.6 and 31.1 N (3.5 and 7.0 lb); amplitude of slip, 165 and 330 μm (6.5 and 13 mils); frequency of slip, 20 and 40 Hz; humidity of air, 16.6 percent, and 58.4 percent relative humidity; and PVC film thickness, 20 and 37 μm (0.8 and 1.45 mils). The 52100 steel balls were loaded against a 1045 steel disk that was coated with PVC. This configuration was then subjected to a two-level, five-factor experiment comprised of the above levels of conditions. / M.S.
