Abstract

Experiments were conducted to determine the coefficient of friction of the inorganic solid film lubricant TIOLUBE 1175 (T1175). The experiments were conducted first at room temperature and at atmospheric pressure. The experiments are then conducted in vacuum at room temperature, at liquid nitrogen temperature (LN2), and at liquid helium (LHe) temperatures. The coefficient of friction is measured between two aluminum specimens coated with T1175 (self friction) at normal loads of 30 to 78 MPa, and a surface velocity of .076 to 0.3 m/min. The coefficient of friction between aluminum and aluminum coated with T1175 increases with normal load, and decreases with temperature. The heating energy generated due to friction is also determined. The experimental apparatus is discussed and the test results are presented.
