The frictional test was examined by dry condition and lubricated condition by using the cast iron, which is known as wear resistance material and used for piston ring and cylinder liner, etc. The S45C steel was examined as a comparison material. The seizure was evaluated from viewpoints of temperature rise, coefficient of friction, wear, and surface damage. As a result, the existence of the boundary lubricating film was confirmed. For lubricated condition, seizure was defined when coefficient of friction increased to 0.3. The critical load, the critical temperature and the amount of the critical heat generation were obtained, when seizure occurred. Moreover, the difference on the wear surface before and after the seizure was detected by the surface observation using SEM, AFM and nano-indenter.
