“…Ni-B coatings are famous for their excellent wear resistance and high hardness coupled with decent characteristics like durability, uniformity of layer thickness, lubricity and ductility, exceptional solderability, decent electrical characteristics, antimicrobial properties, low porosity, excellent bonding, electromagnetic characteristics, etc. [5,6]. Due to these attractive characteristics, Ni-B coatings have found multiple uses in automotive, aeronautics, nuclear, astronautics, petrochemical, electronic devices, plastics, optics, textile, paper/pulp, food, and print industries [7][8][9].…”

Abstract:Ni-B/Y 2 O 3 composite coatings were developed through an electrodeposition process to study the effect of addition of Y 2 O 3 particles on structure, surface, thermal, mechanical, and anticorrosion properties of Ni-B coatings. It is revealed that parent crystal structure of Ni-B matrix is preserved by addition of Y 2 O 3 , however, a noticeable improvement in crystallinity is observed. The analysis of the surface exhibits formation of dense and nodular deposits in the two types of coatings, but incorporation of Y 2 O 3 particles in Ni-B matrix has resulted in a noteworthy change in grain size and surface roughness. Thermal analysis of the surfaces indicates that Ni-B-Y 2 O 3 composite coatings demonstrate superior thermal stability compared to Ni-B coatings. The nanoindentation analysis shows a significant enhancement in the mechanical characteristics of the Ni-B matrix by addition of Y 2 O 3 particles. This may be contemplated as the result of grain refinement and dispersion hardening of the Ni-B matrix by the presence of hard Y 2 O 3 particles. A decent improvement in the corrosion protection efficiency (73.6%) is also observed by addition of Y 2 O 3 particles into Ni-B matrix. Simultaneous improvement of mechanical and anticorrosion properties suggests potential applications of Ni-B-Y 2 O 3 coatings in oil and gas, automobile, and many other industries.

In this letter, the formation of electrodeposited Ni-B and Ni-Co-B alloys by using boric acid as boron source was demonstrated. The estimated thickness of the films was 5 μm. By means of Cyclic voltammetry, X-ray diffractometry and energy dispersive X-ray spectroscopy analyzes, it was showed that Ni-B and Ni-Co-B alloys, with composition Ni 94 B 6 and Ni 75 Co 21 B 4 , can be easily formed onto glassy carbon when no complexing agents are employed in the electrodeposition bath. These results open the door to the production of electrodeposited boron-containing alloys by using boric acid as precursor due to its low cost and large-scale production. © 2014 The Electrochemical Society. [DOI: 10.1149/2.011405eel] All rights reserved.Manuscript submitted January 29, 2014; revised manuscript received March 5, 2014. Published March 25, 2014 Electro-and electroless plated boron-containing alloys have attracted much attention in the last decades due to their uncommon properties such as high hardness and superior mechanical wear resistance.1,2 Moreover, their application is so vast and includes several fields concerning aerospace, automotive, chemical and electrical industries.3 Among them, binary and ternary alloys such as Ni-B, Co-B, Fe-B, Ni-W-B and Co-Ni-B have been studied with different purposes. [4][5][6] In the case of electroless deposition, the use of strong boron-base reducing agents (borohydride, dimethylamine borane, trimethylamine borane, etc.) is mandatory to obtain boron-containing alloys. Besides the relatively high cost of these compounds, the electroless technique to produce boron alloys is limited to the use at high temperatures (70-90• C) and high pH values (13-14), 7 which in many cases restricts its broad utilization. In view of these facts, the conventional electrodeposition technique appears as an alternative to the boron alloys production. In addition, as reported by Bekish et al., 2 the electrochemical method offers a number of considerable advantages when compared to the electroless one, e.g. operation at room temperature, high deposition rate, electrolyte stability, among others. However, studies concerning electrodeposition of boron-based alloys have only showed their production from baths containing the above-mentioned boron compounds. 4-6Here, we report, for the first time, the electrodeposition of Ni-B and Ni-Co-B alloys from a bath containing boric acid as boron source. By means of cyclic voltammetry, X-ray diffractometry and energy dispersive X-ray spectroscopy analyzes, it was demonstrated that Ni-B and Co-Ni-B alloys can be easily deposited from a simple bath. ExperimentalNi-B and Ni-Co-B Alloys were potentiostatically deposited onto a glassy carbon disk (area = 0.075 cm 2 ). Glassy carbon was chosen as substrate due to its good electrical conductivity and long potential range of electrochemical inactivity. The electrolyte composition used for the alloys electrodeposition was: 0.05 M NiCl 2 , 0.5 M NaCl, and 0.2 M H 3 BO 3 for Ni-B alloy, and the same bath plus 0.025 M CoCl 2 for Ni-Co-B ...

“…Due to its excellent mechanical, electrical, physical, corrosion, hardness, friction and wear resistance properties [3], it has a wide range of industrial applications. It is also noted that Ni-B coatings have high hardness and superior wear resistance characteristics [4][5][6][7][8]. It may be applied on irregular and intricate shapes of geometries due to its smooth and uniform deposition over the substrate.…”

Abstract. This paper presents an experimental study on tribological behavior of electroless Ni-B coating under lubricated condition based on Taguchi's method. Mild steel specimens are used as the substrate material for the deposition of Ni-B coating and the thickness of the deposits is found to be around 35 µm. Based on Taguchi's L 27 orthogonal array of experiments, the wear tests are done on a pin-on-disc type tribotester This experiment is carried out by utilizing the combination of process parameters of the tribotester like normal load, sliding speed and duration of sliding. The analysis of the experimental data is carried out with the help of MINITAB® software package. It is seen that the normal load is the most significant factor followed by sliding time at 99% confidence level. The surface morphology, composition and compound analysis of the coatings are done by means of scanning electron microscope, energy dispersed X-ray micro-analyzer and X-ray diffraction analyzer respectively. Finally, a confirmation test is carried out to validate the analysis.
