Synergistic role of carbonaceous reinforcements on multi length scale tribology of electrophoretically deposited nickel-boron nitride coatings

Microstructure and properties of BN/Ni-Cu composites fabricated by powder technology

“…Previous work reported that there is no reaction between nitrogen with Cu at temperatures below 1173 K and the solubility of nitrogen neither in solid Cu nor in liquid Cu up to 1673 K. [38,41]. However, the intermetallic compounds CuN 3 , Cu 3 N and CuN 6 may be formed due to the interaction between the fine copper powder and the nanosized boron nitride.…”

Load-bearing study and interfacial interactions of hydroxyapatite composite coatings for bone tissue engineering

“…Ti a shows the phases ( 100 35 The HAP-hBN shows the specific HAP peaks along with the hBN peak at 26.671 as (002) phase. 41 The XRD pattern was further used to calculate the crystallite size (t) of the deposited coatings employing the Scherrer equation using the full width at half maximum (FWHM, b), a constant k (0.9), the Bragg diffraction angle (y) and the X-ray wavelength.…”

“…35 The HAP–hBN shows the specific HAP peaks along with the hBN peak at 26.67° as (002) phase. 41 The XRD pattern was further used to calculate the crystallite size ( t ) of the deposited coatings employing the Scherrer equation using the full width at half maximum (FWHM, β ), a constant k (0.9), the Bragg diffraction angle ( θ ) and the X-ray wavelength.The lowest crystallite size was found for the HAP–hBN coating (19 ± 1 nm) when compared to that of the HAP (36 ± 2 nm), HAP–CNT (27 ± 1 nm), HAP–GrO (26 ± 1 nm) coatings (Fig. 3a).…”

Nanodiamond-structured zinc composite coatings with strong bonding and high load-bearing capacity

“…7 A well-selected coating can yield signicant benets in terms of cost savings for maintenance and reparation while also providing enhanced protection against wear and corrosion. 8 Until the present time, cadmium plating was widely used in the aerospace industry because of its wear resistance and excellent self-lubricating properties. Despite the advantages, there is a global trend towards replacing these coatings due to heightened environmental concerns and stringent regulations, as cadmium is a heavy toxic metal that causes signicant environmental and health issues.…”
