We present a methodology that allows one to identify the interfacial properties as a function of confinement. Rheology, viscosity as well as elasticity, in both directions (normal and tangential), and static and dynamic forces can be simultaneously m

The Lyon molecular tribometer, a very stiff and sensitive surface force apparatus, was used to investigate the structure, mechanical properties, and some Tribological characteristics of two different dispersions of potassium triborate adsorbed on cob

The wear behaviour of an austenitic stainless steel is analysed using a tribometer working in pressurised high temperature water (PHTW). The precise contact conditions, low pressure impact and sliding contacts, play an important role on the surface w

The lubrication with oil-in-water emulsions is usually supposed to be governed by the oil phase being concentrated in a reservoir that supplies the contact. In this paper, another lubrication process in an elastohydrodynamic ball/disc contact is pres

The lubrication mechanisms of water-based fluids are not yet well understood, especially when extreme load conditions are applied. The example of lamellar crystallite particles in water, provided by an emulsion-like technology, is described in this p

A surface force apparatus (SFA) has been used to determine film thickness and film properties of adsorbed neutral and basic diisobutyl zinc dithiophosphates (ZnDTPs) on cobalt surfaces. Sliding experiments were also carried out and film characteristi

Using a surface force apparatus (SFA), we have studied, first the adhesive force between two smooth amorphous carbon surfaces in air, and second, the repulsive force due to the contact of two brush polymer layers adsorbed on carbon surfaces. Adhesion
