Three point bending fatigue tests were carried out to clarify the effect of Arc Ion Plating (AIP) coating on fatigue strength. The Arc Ion Plating was performed using Cr cathode and N_2 gas. The SUS304 substrate was employed in this study. Coating was carried out under the following conditions; the arc current was changed from 50 to 200 A. The bias voltage was changed from -50 to -500 V. The gas pressure was changed from 1.3 to 5.3 Pa. The results obtained were as follows: (1) The diameter and number of macro particle decreased with increasing the arc current and the bias voltage, also increasing the gas pressure. (2) The hardness of CrN thin film decreased with increasing the bias voltage. (3) When the arc current, the bias voltage and the gas pressure were constant, the fatigue strength of coated specimens for thin film was greater than for thick film.
