Abstract

Effect of TIN and CrN coating films deposited by PVD and CVD methods on fatigue behavior of carbon steel in air and in 3% saline solution was discussed. Fatigue life of metal was improved by coating, but this was affected by some factors, such as an applied stress ratio, stress or strain amplitude, preflaws or flaws in the coating film occurred during fatigue process, coating film thickness and defects in the coating film. 1 Introduction Numerous methods of surface treatment has been developed in the past for the purpose of the increase strength and extension of lifetime of the engineering components. For strength and failure resistance, the most sensitive part of component is its surface for reasons that the surface is directly exposed to unfavorable act
