“…Nikbakht et al [26] reported the formation of a composite Ni-Ti coating on the titanium substrate through a cold spray method followed by a heat treatment. Li et al [27,28] proposed a new method for preparing Ni-Ti intermetallic compounds by nickel plating on titanium substrate followed by electron beam remelting. The authors of the present work have reported the formation of Ni-Ti intermetallic coatings by nickel plating on commercially pure titanium followed by heat treatment [29].…”

In this work, dry tribological behaviors of commercial pure (Cp) titanium and diffusion coated titanium were studied and compared. Wear tests were performed by a pin on disk tribometer using 52100 steel pins, under various loads of 10, 20, and 40 N. Worn surfaces were examined by scanning electron microscope, equipped with EDS analyzer. The wear rates of the coated materials were lower than those of the Cp titanium. This is mainly attributed to the higher hardness of the NiTi layer (about 280 HV) which is 1.5 times higher than that of the untreated titanium (about 180 HV). In addition, the SEM analysis of the worn surfaces revealed that the formation of tribological layer on the surface of the diffusion treated material effectively lowered the wear rate. The results also demonstrated a lower coefficient of friction in the treated specimens compared to those of the Cp materials.

“…e SEM image in Figure 9(c) shows a dense passivation layer formation upon exposure to corrosive medium, which leads to good corrosion resistance and is seen from the elemental spectrum in EDS report shown in Figure 10(c), as observed elsewhere [29]. e Ni coating was effective as it was able to form a coherent layer which seals the pores in the corten steel substrate and prevents outward migration of elements from the substrate as discussed elsewhere [30][31][32][33].…”

Corten steel is a low-carbon alloy steel. It is widely used in architecture, the transport sector, and industrial applications, where the steel is exposed to harsh environments. It is very much sought after due to its auto protection from corrosive environments through the formation of patina (rust). The specialty of patina formed on the corten steel is that it can self-heal itself and stop the spreading of corrosion. Generally, steels are given protective coatings to enhance resistance to corrosion, wear, abrasion, etc. One of the popular protective coating techniques is electroplating. In this study, the effect of electroplating of copper (Cu), zinc (Zn), and nickel (Ni) on the wear and corrosion behavior of Corten ASTM A242 grade steel is investigated. It was observed that the Cu coating yielded poor corrosion and wear protection performance. The Zn coating exhibited a moderate improvement. The Ni electroplating produced excellent results and, the wear and corrosion resistance was improved in the corten steel. Thus, when compared with Cu, Zn, and Ni coatings, the Ni-coated corten steel is an ideal candidate in applications where there is a need for good resistance to wear, abrasion, and corrosion.

“…Titanium would easily react with oxygen in the air and then form loose and porous TiO 2 , which could exacerbate the oxidation of the alloy. Therefore, researchers have used various surface treatment techniques, including electroplating [ 4 ], chemical heat treatment [ 5 , 6 , 7 ], ion implantation [ 8 , 9 ], mechanical surface enhancement technology [ 10 , 11 ], and vapor deposition [ 12 , 13 ], to improve the properties of the surface to meet the application requirements.…”

Titanium and its alloys are widely used in high-end manufacturing fields. However, their low high-temperature oxidation resistance has limited their further application. Recently, laser alloying processing has attracted researchers to improve the surface properties of Ti, for which Ni coated graphite system is an excellent prospect due to its outstanding properties and metallurgical bonding between coating and substrate. In this paper, nanoscaled rare earth oxide Nd2O3 addition was added to Ni coated graphite laser alloying materials to research its influence on the microstructure and high-temperature oxidation resistance of the coating. The results proved that nano-Nd2O3 has an outstanding effect on refining coating microstructures, thus the high-temperature oxidation resistance was improved. Furthermore, with the addition of 1. 5 wt.% nano-Nd2O3, more NiO formed in the oxide film, which effectively strengthened the protective effect of the film. After 100 h of 800 °C oxidation, the oxidation weight gain per unit area of the normal coating was 14.571 mg/cm2, while that of the coating with nano-Nd2O3 addition was 6.244 mg/cm2, further proving that the addition of nano-Nd2O3 substantially improved the high-temperature oxidation properties of the coating.
