The objectives of this study are to examine the influence of coating on the characteristic of fatigue crack growth of the ultra thin sheet of austenite stainless steel SUS304. The side edge notched specimens with thickness of 0.05 mm were fatigue tested under constant tension-tension loading condition after the surface of specimens were coated with sputtered TiN film of 2.0 μm thick using various bias voltages V_B. Two kinds of SUS304 with rolling or with annealing were used as a tested material. The main conclusions are the following. The da/dN-ΔK relationships of coating specimen were affected by the stress condition, da/dN on high stress conditions were larger than that of the substrate specimen, but da/dN on low stress conditions were smaller than that of substrate specimen independent of the tested material. The influences of V_B on the da/dN-ΔK relationships were a little observed.
