“…The new fretting tribometer (Vibro Thermo Tribometer -VTTM) is designed as an ambient and high temperature evolution of a cryotechnical environment fretting test rig (Vibro Cryo TriboMeter -VCTM) already in use at LISMMA laboratory [11]. It is based on the same principle, but optimized in order to increase the frequency, displacement amplitude and normal load operating range.…”

“…Contact measurement methods generally involve LVDT (Linear Variable Differential Transformer) sensors [12,13]. Contactless methods regroup Eddy current sensors [11] and optical methods: digital image correlation [12], LDV (Laser Doppler Vibrometers) [9,14] and photonic optic fibres sensors [15]. Eddy current sensors require a specific target with size constraints, and compatible material requirements.…”

Experimental approaches to study fretting are heavily dependent on the performances of the test devices, especially considering the extensive use of quantitative parameters extracted from fretting loops. The dynamic response of a newly designed high temperature test bench is analysed to define the practical test range and identify dynamic disturbance sources. Displacement and load metrology are studied, leading to a direct comparison of two tangential load measurement methods. Accounting for the inertia loads and the elastic properties of the guiding system allows to increase the frequency operating range of the test bench.

“…To measure the tangential force, in addition to the force sensor (12) attached to the longitudinal actuator (13), the fixed head (21) of the machine is equipped with a force sensor (20). The tangential force Q is calculated from efforts F 1 and F 2 measured by sensors (12) and (20), hence:…”

The device presented in this work enables a conventional fatigue machine to be adapted so that it can be used as a tribometer. The DEMAFtrib (Device using Fatigue Machine as Tribometer) adds a second axis to a uniaxial fatigue machine in the form of an add-on accessory. It allows the measurement of wear and friction forces at the contact point of two surfaces in relative motion. The apparatus can also be used as a fretting-wear machine or a fretting-fatigue machine. This device can be used in mechanical-testing laboratories equipped with a fatigue machine and presenting a need to characterize materials under wear and fretting. A sample of study results on the wear and fretting of 7075 aluminium is presented as an application of the use of the DEMAFtrib in tribological and fretting tests.

International audienceTitanium alloys are commonly used to lighten aeronautical structures. Unfortunately, their poor tribological properties need to confer onto the surface both high mechanical resistance under load and low friction/low wear against other metals. Based on amorphous silicon carbide (a-SiC:H), periodic multi-nano-coatings have been found to be candidates for this use. Such coatings were deposited on Ti surfaces using multifrequency plasma CVD devices. Scratch-testing measurements have revealed that the critical loads corresponding to cohesive/adhesive cracks are significantly increased using multilayered stacks. fretting-wear tests also revealed the influence of multilayer architecture and preliminary analysis of wear tracks and material transfers leaded to a first classification of the coatings
