On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing [PDF]
Sensors, 2020 In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, are analysed and modelled ...

Numerical modeling of fretting wear [PDF]
International Journal Sustainable Construction & Design, 2013 In this paper, a review of some techniques proposed in the literature for modelling fretting wear is presented. Fretting wear occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces.

A Numerical Study on the Effect of Debris Layer on Fretting Wear. [PDF]
Materials (Basel), 2016 Fretting wear is the material damage of two contact surfaces caused by micro relative displacement. Its characteristic is that debris is trapped on the contact surfaces.

Effect of frequency on fretting wear behavior of Ti/TiN multilayer film on depleted uranium. [PDF]
PLoS ONE, 2017 The Ti/TiN multi-layer film was prepared on the depleted uranium (DU) substrate by cathodic arc ion plating equipment. The character of multi-layer film was studied by SEM, XRD and AES, revealed that the surface was composed of small compact particle and

Effect of elastic grading on fretting wear. [PDF]
Sci Rep, 2019 AbstractWe consider fretting wear in elastic frictional contact under influence of oscillations of small amplitude and investigate the question, how wear damage can be influenced by the introduction of material gradients. To achieve a general understanding we restrict our consideration to media with a power-law dependency of the elastic modulus on ...

Fretting Wear Characteristics of Nuclear Fuel Cladding in High-Temperature Pressurized Water
Chinese Journal of Mechanical Engineering, 2023 In pressurized water reactor (PWR), fretting wear is one of the main causes of fuel assembly failure. Moreover, the operation condition of cladding is complex and harsh.
