Abstract
Three point bending fatigue tests were carried out using S45C steel with CrN film. The film was coated onto S45C steel by arc ion plating method. In order to investigate the effect of coating condition on the fatigue behavior, the films were coated under two different conditions. As a result, the fatigue strength was increased coated under low arc current and bias voltage, while the fatigue strength of high arc current and bias voltage. The change of the fatigue behavior was mainly caused by the difference of crack initiation.
