Abstract

The effect of TIN film on low-cycle fatigue behavior of steel coated by PVD method K. Shiozawa, L. Han Department of Mechanical System Engineering, Faculty of Engineering, Toyama University, 3190 Gofuku, Toyama 930, Japan ABSTRACT Strain controlled low-cycle fatigue test was conducted in air, using the specimen of 0.37% carbon steel coated with TiN by PVD method. Increase in fatigue life of coated specimen was observed under the region of low strain amplitude,below A e t=0.35—0.40% as compared with that of uncoated specimen. On the other hand, fatigue life of coated specimen decreased at the region of high strain amplitude, for reasons of many cracks induced to initiate at the substrate by rupture of coating film. INTRODUCTION The production of thin layers of titanium nitride (TiN) on the surfaces of various engineering components by a variety of techniques has received considerable attention in the past few years. A number of superior properties
