“…Solid-phase coatings with three compositions (wt.%): B 4 C; B 4 C-40% BN; B 4 C-40% BN-10% Li 2 O were deposited onto steel 10 substrates with a size of 10101 mm. According to the previous studies, the last two compositions provided a high degree of hardness and excellent anti-friction surface properties measured in friction tests under conditions of dry slipping friction at elevated contact loads [14].…”

Short-pulse laser treatment was used to deposit boron carbide and nitride-based ceramic coatings on a non-alloy steel surface. The coatings thus obtained show promising properties in terms of high hardness, wear resistance, adhesion to the substrate, and low coefficient of friction. In parallel, the coatings obtained were characterized by reduced corrosion resistance in a model borate buffer solution and under conditions of recurrent water vapor condensation in a thermal humidity chamber. Preliminary treatment of samples with solutions of some inhibitors made it possible to reduce anodic currents substantially in potentiodynamic experiments. The addition of benzotriazole, mercaptobenzothiazole, and potassium dichromate proved to be effective. Electrochemical and atmospheric corrosion tests revealed that preliminary exposure of the samples to solutions of the inhibitors indicated above made it possible to reduce the corrosion rate significantly compared to the untreated samples. Potassium dichromate occurred to be most effective.

“…The coatings were characterized by a low roughness (Ra 0.4) and dry sliding friction coefficient (up to 0.02) determined by sliding against a tungsten carbide counterface under contact loads of up to 120 MPa. The reasons for the improved anti-friction properties of the coatings are discussed in [14].…”

Boron nitride is an artificial wide band gap material. It is very hard in cubic form (cBN) as well as diamond, and it is very soft in hexagonal form (hBN). In this paper, the optical and nano-mechanical properties of carbon coated boron nitride nano sheets (C-BNNSs) thin films were deposited onto copper (Cu), stainless steel (SS), Ti 6 Al 4 V substrates. The band gap of C-BNNSs thin film was determined as 3.61 eV. Mean grain heights of the film were approximately 400 nm, 100 nm and 105 nm for the film deposited onto Cu, SS and Ti6Al4V substrate, respectively. Cubic phase rates of BN were calculated approximately 34%. Roughness (Ra) of the films are approximately the same and its value was approximately 20 nm. Hardness of the films were 20 GPa at 20 nm depth. According to results, C-BNNSs material is proper for the semiconductor and optoelectronic applications.

“…For instance, while examining AlTiN-DLC (diamond-like carbon, DLC) coating [ 11 ] it was concluded that softer coating exhibits a lower wear rate due to carbon formation on the friction surface. In [ 12 ], wear and hardness reduction of superhard coatings based on boron carbides and nitrides appeared after the addition of graphite and molybdenum disulfide. In [ 13 ], the authors revealed a decreae of the wear in Fe-Ti-SiC based nanocomposite coating containing MgC2 due to graphite release which affected hardness.…”

Potential relations of tribological characteristics of aluminum antifriction alloys with their compositions and mechanical properties were investigated. In this regard, the properties of eight aluminum alloys containing tin from 5.4% to 11% doped with lead, copper, silicon, zinc, magnesium, and titanium were studied. Mechanical properties such as hardness, strength, relative extension, and impact strength were analyzed. Within the tribological tests seizure load and wear of material were evaluated and secondary structures were studied afterwards. The absence of a definitive correlation between tribological behavior and mechanical properties was shown. It was determined that doping tin over 6% is excessive. The seizure load of the alloys increases with the magnesium content. Secondary structures of the alloys with higher wear rates contain one order less magnesium and tin.
