Wear and fretting fatigue behavior of titanium alloy coated with functionally graded TiN film by ion beam assisted deposition

Nihon Kikai Gakkai ronbunshu, 2015
The effect of functionally graded TiN coating on the wear and fretting fatigue behavior of titanium alloy was investigated. The two kinds of monolayer TiN coatings and three kinds of functionally graded TiN coatings were deposited on Ti-6Al-4V alloy ...

STUDY OF TRANSITION IN THE FRETTING PHENOMENON BASED ON THE VARIABILE COEFFICIENT OF FRICTION [PDF]

Fiabilitate şi Durabilitate
Fretting is now fully identified as a small amplitude oscilatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e.

Mechanisms of Fretting Fatigue

JSME international journal. Ser. A, Mechanics and material engineering, 1995
Fretting fatigue is one of the most important phenomena for inducing a dramatic reduction of fatigue strength and consequently, of unexpected failure accidents. There are numerous works on fretting fatigue. The objective of the present review is to clarify fretting fatigue mechanisms based on the vast amount of research work.

Length Scale Considerations in Fretting Fatigue

, 2000
The presence of fretting can be shown to decrease the fatigue life of a component by accelerating crack initiation and subsequent propagation. Behavior in the “long crack” regime may be adequately explained using linear-elastic fracture mechanics. In contrast crack initiation is complex and much more difficult to understand.

Fundamental Investigations of Fretting Fatigue : Part 2, Fretting Fatigue Testing Machine and Some Test Results

Transactions of the Japan Society of Mechanical Engineers, 1968
In the present paper, the construction and features of a fretting fatigue testing machine designed by the authors are explained, and the experimental results obtained by using the testing machine are stated concerning mainly the relative slip which is considered to be one of the most significant factors affecting the fretting fatigue strength.

Fretting Fatigue Behavior under Tension–Bending Mixed-Mode Loading

Applied Sciences
The mixed-mode loading fretting fatigue caused by the complex geometry of components and combinations of boundary conditions is a common failure mechanism in engineering components, which can dramatically reduce fatigue life. In this paper, a cylinder-on-
