Abstract
Coefficleats of static friction were determined for mild steel rubbing on mild steel, Ti RC 130B on mild steel, Ti RC 130-B rubbing on U, U rubbing on U, Be rubbing on U and Le rubbing on Ti for both statically and dynamically applied loads. Normal rubbing pressures range between 1500 and 12,000 psi for statically applied loads and between 12,000 psi and 21,000 psi for dynamically applied loads. Coefficients of kinetic friction have been determined between varlous metals for rubbing speeds between 30 and 50 fps and rubbing pressures of 1600 to 3,000 psi. (auth)
