“…Graphite‐like carbon nanostructures exist in the friction layer formed on the steel ball surface. At the same time, it can also be observed that curve 4 in the inset of Figure 7C has a peak of h‐BN (1367 cm –1 ), [ 43–45 ] which further illustrates that the transfer film contains h‐BN. In addition, the wear track is significantly smaller than DLC films, more nano materials are accumulated on the wear scar, and the surface of the wear track is smoother.…”

Green tribology is an engineering field, which is dedicated to reducing friction, wear and pollution to the environment. Diamond‐like carbon (DLC) films as coating is a very effective green friction material, but its friction of coefficient in the atmospheric environment still needs to be further reduced. Here, a common method for improving the tribological performance of DLC films in ambient atmosphere by adding 3D graphene/hexagonal boron nitride(h‐BN) composite nanomaterials as lubricant additive is proposed. By comparing with DLC film and other single additives, we can see that the 3D graphene/h‐BN composite nanomaterial as a lubricating additive reduce the friction coefficient and wear rate remarkably. By studying the tribological properties of the surface of the steel ball and DLC film, it is found that the friction protective film containing carbon, nitrogen and boron elements are formed on the surface. The presence of the friction layer can reduce friction efficiently, not only prevent the surface of the steel ball from being excessively worn, but also protect the DLC film from being damaged. The important thing is that it does not contain harmful elements and provides a new reference for the development of the next generation of oil‐free lubrication tribology. Accordingly, it is considered an environmentally friendly additive.

“…191,192 For example, the integration of h-BN with amorphous carbon improves its superb oxidation resistance and chemical stability, thus promoting its great potential to achieve low friction and wear in humid environments. [193][194][195] To explore the specic role of amorphous carbon in h-BN composites, Tian and group 196 discussed the role of h-BN nanomaterials as additives aer covalently graing with sucrose molecules under a sugar-assisted mechanochemical exfoliation method and wrapped with amorphous carbon, 184 which could be dispersed in both water and organic liquids with low friction or ultra-low friction. The h-BNamorphous carbon composites could help reduce the friction coefficient and wear track width by 0.09 and 65 mm, respectively, owing to the interlayer sliding effect of boron nitride nanosheets and the formation of B, N, C, and O tribolm on the sliding interface.…”

“…Metal friction pairs face various atmosphere environments during service, such as high temperature, methane, dry nitrogen, dry air and humid air [1][2][3][4]. In particular, humid air is a very important service environment, and the surface of metal friction parts should be modified to have a high hardness and high chemical inertness in order to offer an excellent corrosion resistance and wear resistance.…”

Humid air is a very important service environment, in which metal friction parts should be enhanced to offer excellent corrosion resistance and wear resistance. The B4C coating is an excellent candidate material to enhance the corrosion resistance and tribological behaviors. The purpose is to investigate the effect of negative bias voltages on the tribological properties of B4C coatings under a high relative humidity environment. Amorphous B4C coatings were successfully prepared by closed field unbalanced magnetron sputtering technology and its microstructure, hardness, elastic modulus, adhesive force and tribological properties were systematically studied. Results demonstrate that the B4C coatings deposited at each negative bias voltage have a columnar structure and the surface roughness remained unchanged (about 1.0 nm), while the thickness, hardness, elastic modulus and adhesion force increase first and then decrease with the negative bias voltage increasing. Among them, the B4C (−50 V) coating showed the best mechanical properties. It should be noted that the B4C (−50 V) coating with an excellent corrosion resistance also exhibits the lowest friction coefficient (~0.15) and wear resistance (7.2 × 10−7 mm3·N−1·m−1) under humid air (85% RH). This is mainly due to the tribochemical reaction of B4C during a sliding process to produce boric acid at the sliding interface. B4C coatings can provide an excellent corrosion resistance and high wear resistance due to their high chemical stability and high hardness.
