“…Figure 7c shows that the coating added with 14 wt.% TiB 2 (W3) showed extremely high wear resistance, with only a few scratches and oxide films forming on the wear surface, which was almost smooth compared to the other coatings. This was attributed to the effective distribution of the TiB 2 enhanced phase reducing the wear of the composite coating [54]. In addition, the hard phases Cr 7 C 3 and TiC generated by the 15 wt.% coating reduced plastic deformation and improved the overall wear resistance of the coating compared to the W5 coating without nickel-coated graphite.…”

To improve the anti-wear and friction-reducing properties of self-lubricating coatings, Ni60/Nickel-coated graphite/TiB2 composite coatings with different contents were prepared by laser cladding. The coating properties were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), energy spectrometer (EDS), electrochemical workstation, micro-Vickers hardness tester, and friction and wear tester. The results showed that with the increase in TiB2 content, the graphite morphology changed from spherical at 0 wt.% TiB2 content to a little black graphite alone at 14 wt.% TiB2 to irregular agglomerates at 22 wt.% TiB2. Furthermore, the hardness of the coatings increased with increasing TiB2 content, and the 63% Ni60 + 15% nickel-coated graphite + 22% TiB2 coating had the highest hardness. TiC and Cr7C3 were generated in the coatings with the addition of nickel-coated graphite, creating a dispersion reinforcement effect, so that the hardness of these coatings was higher than that of the 86% Ni60 + 0% nickel-coated graphite + 14% TiB2 coating without the addition of nickel-coated graphite. In addition, the 71% Ni60 + 15% Ni-coated graphite + 14% TiB2 coating had the lowest friction coefficient, wear loss, and wear volume, thus exhibiting excellent friction reduction and anti-wear properties. The 71% Ni60 + 15% nickel-coated graphite + 14% TiB2 coating had excellent corrosion resistance.

“…Recently, it has been found that trace TiC particles can refine the grain and improve the mechanical properties of the alloy [16,17], enhancing the grain boundaries and thus inhibiting generation and expansion of cracks [18]. The addition of trace TiB 2 particles to the alloy can obtain a denser alloy with fewer defects, thus improving the mechanical properties of the alloy [19,20]. Consequently, TiC and TiB 2 ceramic particles are added to Ni-Ti-Cu ternary alloys.…”

In this study, Ni50Ti40Cu10 and Ni45Ti40Cu15 alloy thin-walled parts are prepared on the surface of Ti plates using laser additive manufacturing technology. The optimum operational parameters are explored through a two-factor controlled variable method, based on which the effects of TiC, and TiB2 addition on the forming quality of Ni50Ti40Cu10 and Ni45Ti40Cu15 alloys are further investigated. SEM, EDS, and other testing methods are used to determine the microstructure composition and distribution, and the composition of the physical phases of the alloy, and tensile and hardness tests are carried out to study the mechanical properties of the alloy. The results show that the optimum operational parameters for laser additive manufacturing of thin-walled Ni50Ti40Cu10 and Ni45Ti40Cu15 alloys are 1250w laser power and 300mm/min scanning speed. 0.6wt% TiC addition can achieve better forming quality of the thin-walled parts. The thin-walled Ni50Ti40Cu10 alloy precipitates significantly more Ti2Ni strengthening phases than the thin-walled Ni45Ti40Cu15 alloy. Ni50Ti40Cu10 strength and 45.4% higher elongation compared to Ni45Ti40Cu15 alloy. The average hardness of Ni45Ti40Cu15 is 3.4% lower than that of Ni50Ti40Cu10 alloy.
