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 ...

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 ...

A Numerical Study on the Effect of Variable Wear Coefficient on Fretting Wear Characteristics. [PDF]
Materials (Basel), 2021 Fretting wear is a common phenomenon that happens between contact parts when there is an oscillatory relative movement. To investigate wear characteristics history in the fretting process, the finite element method (FEM) is commonly applied to simulate the fretting by considering the wear in the model.

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
