“…Similar rolls have been widely reported for the mild wear of hard materials, e.g. in the sliding wear of SiC-Al2O3 nanocomposites [12], Si3N4 [13], Al2O3 [14] and diamond-like carbon films [15]. The structure and origin are still a matter of debate.…”

TiAlN/VN multilayer coatings exhibit excellent dry sliding wear resistance and low friction coefficient, reported to be associated with the formation of self-lubricating V2O5. To investigate this hypothesis, dry sliding ball-on-disc wear tests of TiAlN/VN coatings on flat stainless steel substrates were undertaken against Al2O3 at 25 0 C, 300 0 C and 635 0 C in air. The coating exhibited increased wear rate with temperature. The friction coefficient was 0.53 at 25 0 C, which increased to 1.03 at 300 0 C and decreased to 0.46 at 635 0 C. Detailed investigation of the worn surfaces was undertaken using site-specific transmission electron microscopy (TEM) via focused ion beam (FIB) microscopy, along with Fourier transform infrared (FTIR) and Raman spectroscopy. Microstructure and triboinduced chemical reactions at these temperatures were correlated with the coating's wear and friction behaviour. The friction behaviour at room temperature is attributed to the presence of a thin hydrated tribofilm and the presence of V2O5 at high temperature.

“…Under synthetic perspiration, liquid at the contact interface can decrease the frictional resistance. Also, during the wear test in synthetic perspiration, the tribo-chemical reactions could easily occur between materials and water (Ref 14,15). Then, Si(OH) 4 and TiO 2 could form lubrication films in the contact area.…”

The tribological properties of magnetron sputtered titanium nitride coating on 316L steel, sliding against Si 3 N 4 ceramic ball under dry friction and synthetic perspiration lubrication, were investigated. The morphology of the worn surface and the elemental composition of the wear debris were examined by scanning electron microscopy and energy dispersive spectroscopy. TiN coatings and 316L stainless steel had better tribological properties under synthetic perspiration lubrication than under dry friction. Among the three tested materials (316L, 1.6 and 2.4 lm TiN coatings), 2.4 lm TiN coating exhibits the best wear resistance. The difference in wear damage of the three materials is essentially due to the wear mechanisms. For the TiN coating, the damage is attributed to abrasive wear under synthetic perspiration lubrication and the complex interactive mechanisms, including abrasive and adhesive wear, along with plastic deformation, under dry friction.

“…Figure 10 shows the optical micrographs of the Cu pins slid against Al discs in the presence of various lubricants. The wear rate of the pin was assessed by measuring the wear scar radius (r) and then applying the wear volume (V ) equation as described by Fischer & Tomizawa (1985):…”

“…In work done by Liang & Jahanimir (1995), drilling experiments with sapphire tools indicated that the addition of boric acid to distilled water increased the rate of drilling of polycrystalline alumina by a factor of 2. In addition, boric acid was found to help reduce friction and corrosion when mixed with cutting and grinding fluids (Fischer & Tomizawa 1985;Barton et al 2004). In Barton's work, pin-on-disc experiments were conducted at high speeds using the test apparatus shown in figure 2.…”

As the industrial community moves towards green manufacturing processes, there is an increased demand for multi-functional, environmentally friendly lubricants with enhanced tribological performance. In the present investigation, green (environmentally benign) lubricant combinations were prepared by homogeneously mixing nano-(20 nm), submicrometre-(600 nm average size) and micrometre-scale (4 mm average size) boric acid powder additives with canola oil in a vortex generator. As a basis for comparison, lubricants of base canola oil and canola oil mixed with MoS 2 powder (ranging from 0.5 to 10 mm) were also prepared. Friction and wear experiments were carried out on the prepared lubricants using a pin-on-disc apparatus under ambient conditions. Based on the experiments, the nanoscale (20 nm) particle boric acid additive lubricants significantly outperformed all of the other lubricants with respect to frictional and wear performance. In fact, the nanoscale boric acid powder-based lubricants exhibited a wear rate more than an order of magnitude lower than the MoS 2 and larger sized boric acid additive-based lubricants. It was also discovered that the oil mixed with a combination of sub-micrometre-and micrometre-scale boric acid powder additives exhibited better friction and wear performance than the canola oil mixed with sub-micrometre-or micrometre-scale boric acid additives alone.
