From the reliable point of view of the threaded joints, this paper describes the effects of Cr and Al films between contact surfaces on the dynamic sliding coefficient in threaded joint estimated by the staircase method. The factors taken in the experiment are tightening force, amplitude and mean of external load, and coated film on contact surfaces of the threaded joints. The main results obtained are as follows : (1) From the estimation of dynamic sliding coefficient between threaded contact surfaces by the staircase method, it is found that the dynamic sliding coefficient between threaded contact surfaces is lower than static sliding coefficient under any condition of contact surface, that is coated with Cr or Al film. (2) It is recognized from the experimental results that the chromium film is useful for the static sliding coefficient and the dynamic sliding coefficient between threaded contact surfaces.
