TL;DR: In this paper, the authors have reported on the development of a biodegradable electroless Ni-B bath and evaluated its characteristic properties, and the influence of bath constituents, temperature and pH on the rate of deposition was studied.
Abstract: Electroless deposition process has undergone numerous changes to meet the challenging needs for a variety of industrial applications ever since the invention of the process during 1947. Among the various metals that can be electrolessly plated, electroless nickel has proved its supremacy for producing coatings with high corrosion resistance, hardness, wear resistance and uniformity. Electroless nickel can be deposited from a variety of baths and the coating properties depends upon the type of reducing agents and other deposition conditions. Electroless nickel–boron coatings have received considerable interest nowadays because of the superior hardness, corrosion and wear resistance characteristics. In this paper, the authors have reported on the development of a biodegradable electroless Ni–B bath and evaluated its characteristic properties. The influence of bath constituents, temperature and pH on the rate of deposition was studied. Scanning electron microscopy, X-ray diffraction, X-ray fluoresce...

TL;DR: In this article, the authors have reported on the development of new bath formulation for getting Ni-Co-P nanoalloy deposit and optimised bath concentration and operating conditions, they have found that the alloy is nanocrystalline in nature, and the particle size is around 37-45
Abstract: Electroless plating have unique metallurgical characteristics, and the deposits can be made onto a wide range of substrates, including both metallic and non‐metallic surfaces. In this paper, the authors have reported on the development of new bath formulation for getting Ni–Co–P nanoalloy deposit and optimised bath concentration and operating conditions. The alloy deposit contains 10·59%Co in the Ni–P matrix. There is an increase in hardness and corrosion resistance of the deposit with the incorporation of Co. Furthermore, from the XRD measurements of the deposits, it was found that the alloy is nanocrystalline in nature, and the particle size is around 37–45 nm. Atomic force microscopy results show that the height of the particles is in nanosize, and roughness of the surface is within 3 nm.

TL;DR: In this article, high-boron electroless nickel was synthesized on mild steel substrates by modification of the plating conditions of a mid-bron (5-6-wt% B) plating bath.
Abstract: High-boron (7–9 wt%) electroless nickel-coatings were synthesized on mild steel substrates by modification of the plating conditions of a mid-boron (5–6 wt% B) plating bath. They were fully characterized and compared when possible with the coatings obtained in the usual operating conditions, before and after a heat treatment at 400 °C for 1 h in a protective atmosphere. The morphology of the coating was similar to mid-boron coatings and left unchanged by heat treatment. Similarly, most properties of the as-deposited coatings were similar for mid and high-boron coatings. However, the effect of heat treatment was very different on both types of coatings: while mid-boron coatings crystallized fully in the Ni 3 B system, high-boron was multiphased. The coatings also presented a difference in terms of hardness behavior with a very important increase for the mid-boron coatings and lesser modification in the case of high boron. The abrasive wear resistance of both kinds of coatings was similar before heat treatment and high-boron coatings had a slightly better behavior after heat treatment. However, the sliding wear behavior of mid-boron coatings is significantly better than that of high-boron electroless nickel.
