“…These results suggested that the chemistry of the SiO 2 surfaces contributes to the wear of the material at loads lower than the hardness value causing mechanical deformation of the material. The proposed mechanism for wear of the native oxide layer, the creation of siloxane bridges (chemical bonds) [120], could pertain to the glass wear behavior [121,122]. A surface force apparatus study found that the adhesion force of two silica surfaces in humid conditions was greater than the capillary force expected from water [123].…”

Tribology involves not only two-body contacts of two solid materials-a substrate and a counter-surface; it often involves three-body contacts whether the third body is intentionally introduced or inevitably added during the sliding or rubbing. The intentionally added third body could be lubricant oil or engineered nanomaterial used to mitigate the friction and wear of the sliding contact. The inevitably added third body could be wear debris created from the substrate or the counter surface during sliding. Even in the absence of any solid third-body between the sliding surfaces, molecular adsorption of water or organic vapors from the surrounding environment can dramatically alter the friction and wear behavior of solid surfaces tested in the absence of lubricant oils. This review article covers the last case: the effects of molecular adsorption on sliding solid surfaces both inevitably occurring due to the ambient test and intentionally introduced as a solution for engineering problems. We will review how adsorbed molecules can change the course of wear and friction, as well as the mechanical and chemical behavior, of a wide range of materials under sliding conditions.

“…It was believed that the silica surface was chemically reactive enough to form Si-O-Si bridging bonds between two sliding solid surfaces, while the diamond surface was chemically inert (or not reactive enough) to induce the tribochemical wear of silica surface. It was also observed that the nanowear of silicon surfaces could be prevented when rubbing with the SiO 2 tip in ethanol vapor, and the hillock formation by the diamond tip was reduced by 80% in ethanol vapor, compared to the one formed in humid air [15]. These reports suggest that the chemical reactivity of counter-surfaces play important roles in the mechanochemical wear of sliding interfaces.…”

“…For example, the nanowear results of silicon surfaces could vary significantly when rubbing against different countersurfaces [14][15][16]. A deep wear of silicon in humid environments occurred only when the counter-surface was SiO 2 , while a hillock formation on the silicon substrate was observed when the counter-surface was diamond [14].…”

a b s t r a c tThe effects of counter-surface chemistry on the friction and wear of soda-lime-silica glass were investigated using a ball-on-flat tribometer with various ball materials (stainless steel, silicon nitride, and alumina) in dry and humid environments. It was found that the interfacial wear was very sensitive to environmental humidity and counter-surface chemistry. In dry conditions, soda-lime glass was damaged mechanically regardless of counter-surface materials, creating a rough and deep wear track. These results were consistent with the Archard relationship-a softer material would wear mechanically by a harder material. However, in humid conditions, the ball materials that were harder than the soda-lime glass were damaged. Thus, the wear of glass interfaces under humid conditions does not follow the Archard relationship. These results clearly show that the tribochemical reactions involving the substrate and counter-surface chemistry as well as the adsorbed water molecules are determining factors governing wear behaviors in humid environments.

“…All nanowear tests were performed by an AFM system equipped with an environmental control system and a relative humidity (RH) detector (HP22-A, Rotronic, Switzerland), as shown in Figure 1(a). More details of these systems could be found in a previous publication [19]. Two kinds of AFM tips were used: Previous investigations reported that the hillock-like protrusion could be formed at silicon and quartz surfaces under nanoscale friction and wear testing [20].…”

The nanoscale friction and wear behaviors of soda-lime-silica (SLS) glass were studied using atomic force microscopy (AFM) using diamond (inert) and silica (reactive) tips in dry and humid environments. Depending on the contact pressure, counter-surface chemistry, and humidity, three distinct wear regimes were identified: mechanical wear, stress corrosion, and tribochemical wear. The mechanisms of material removal at these three wear regimes were proposed. These results provided insights into mechanical and mechanochemical wear mechanisms of the SLS glass at nanoscale, which will be useful to optimize tribological designs of functional and engineering glasses.
