“…In biomedicine as well as in other applications, the surface microstructure modification and/or coating have been assessed as strategies to improve the surface properties of Ti alloys. Physical and chemical vapor deposition (PVD and CVD) have been explored as coating processes to produce ultra-hard films on Ti alloys [4][5][6], but also recently other processes as DC reactive magnetron sputtering [7,8], electrodeposition [9], nitriding [10], laser surface treatment [11], solid state diffusion [12] and ion implanting [13], have been also proposed. Most of those techniques are limited by requirements of "atmosphere" or "pre-placement", complexity or high cost, making these processes difficult to implement in practice.…”

A B S T R A C TThe hardness and corrosion resistance of TiN coatings, processed by Electrophoretic Deposition (EPD) to cover polished and unpolished Ti substrates, have been evaluated. A deposition time of 5 min has been enough to obtain a cohesive layer of 7-8 μm in thickness. The coatings were thermally treated in vacuum atmosphere at 1200°C for 1 h with heating and cooling rates of 5°C min The nanohardness values of the polished samples have been increased from 2.8-4.8 GPa up to 6.5-8.5 GPa. Besides, the corrosion current density has been reduced more than one order of magnitude obtaining a protective efficiency of 82%. These values have been compared with other works in literature where authors used complex and costly processing techniques, demonstrating the strong impact of the colloidal processing over the specific properties of the material.

“…and borides (TiB) [18] as well as TiN mixtures with different alloys (NiTi, FeNi) [9] are extensively considered in the literature as Ti coatings, as monolayer or even in multilayer systems (i.e. TiN/AlN, TiN/TiCN) [5,19,20], to improve the surface toughness and corrosion properties.…”

“…The results are in accordance with our earlier studies. 7,11 Corrosion polarization.- Figure 12 shows the corrosion polarization curves for Ni-Fe alloy and Ni-Fe/Si 3 N 4 -TiN nanocomposite coatings in 3.5% NaCl solutions. Both of the curves show an active but poor passive transition in anodic branch, but the corrosion potential of Ni-Fe/Si 3 N 4 -TiN nanocomposite coating is more positive than that of Ni-Fe coating.…”

Functional Ni-Fe/Si 3 N 4 -TiN nanocomposite coatings were electro-codeposited from sulphamate-N,N-dimethylformamide bath containing dispersed Si 3 N 4 and TiN nano-particles 10 g/L each. The effect of current density on the incorporation of the ceramic particulate and on the properties of the deposits was investigated. The deposited coatings were characterized using various advanced techniques such as scanning electron microscopy, X-ray diffractometry, transmission electron microscopy and atomic force microscopy. Physical properties such as microhardness, corrosion resistance and magnetic property of the composite were evaluated. Results indicated that Si 3 N 4 and TiN both the ceramics has prodigious effect on the microstructure and properties of the coating. Ni-Fe/Si 3 N 4 -TiN coatings showed higher hardness in comparison with the Ni-Fe, Ni-Fe/Si 3 N 4 and Ni-Fe/TiN coatings. Hardness values of the coatings ranged from 650 HV to 773 HV and the coating with maximum hardness was obtained at current density 3.0 A dm -2 . Further, significant influence had been observed on corrosion resistance by the ceramic particles. Magnetic investigations revealed characteristic superparamagnetic behavior of the coatings.Composites or nanocomposites possess unique physical and mechanical properties formed by mixing two or more dissimilar materials at micro or nanoscale. Nanocomposites are used when a combination of properties is needed not found in a single material. 1 Nanocomposite materials offer enormous potential for new applications across aerospace, automotive, electronics, biomedical, reinforced lightweight materials, sensors, batteries, energy conversion and many other industries. 2 Particle reinforced nickel-based alloys/composites have received much interest owing to their superior physical and mechanical properties: better hardness, high strength, and better electrical and anticorrosion properties. Among these, Ni-Fe alloy is of significant interest because of its interesting mechanical, electrical and magnetic properties. Reinforcement of metallic matrix with nano-sized ceramic particles renders it with enhanced strength. 3 Ceramic particles have very high hardness, very high elastic modulus, high thermal expansion, high corrosion resistance, high wear resistance and low density in comparison to metals. Nitride ceramics are often refractory materials, owing to their high lattice energy which reflects the strong attraction of N 3-for the metal cation. TiN and Si 3 N 4 are used as cutting materials and hard coating materials. Due to the large bandgap, most of the nitride ceramics are insulators.Currently, there are several fabrication methods for nano-sized ceramic particulate reinforced metal matrix composites, including milling, sintering, casting, physical vapor deposition, chemical vapor deposition, electrodeposition, sol-gel, etc. 2 Among these methods, composite electrodeposition has been identified to be a greener route, 4 continuous, easy to control, attractive for their capability of producing composites wi...
