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 by AIP3000 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) Difference of the crack growth behavior is affected by macro particles in film.
