“…6) [43] . This structure produced by selective etching traps the light and is capable of absorbing over 99% light in solar region (0.3-2 μm) [44] . Moreover, these surfaces are extremely suitable in improving the absorption of thermal detectors and to minimize the effect of stray and scattered light in optical instruments and sensors.…”

The development of metal deposition processes based on electroless nickel, alloy and composite coatings on various surfaces has witnessed a surge in interest among researchers, with many recent applications made possible from many excellent properties. In recent years, these coatings have shown promising corrosion and wear resistance properties and large number of newer developments became most important from macro to nano level 1 applications. After a brief review of the fundamental aspects underlying the coating processes, this paper discusses in detail about different electroless nickel alloy, composite, nano plating, bath techniques, preparation, characterization, new depositing mechanism and their recent applications, including brief notes on difficult substrate and waste treatment for green environment. Emphasis will be on to their recent progress, which will be discussed in detail and critically reviewed.

“…The blackening of electroless nickel deposit is obtained when the deposit is dipped in a nitric acid solution (9 M). The blackening results from hole formation visible first on the boundaries between the different nodules and then on the whole deposit surface, as seen by SEM [10]. This structure produced by selective etching traps the light and is capable of absorbing over 99% light in solar region (300-2000 nm) [11].…”

A process of blackening of electroless nickel coating is investigated to produce ultra black coating on titanium alloys with higher optical properties. Process optimization was carried out by investigating the influence of various operating conditions, namely, processing time of etching solutions, thickness of electroless nickel deposit, temperature of blackening solutions, and pH of electroless nickel solution on the physico-optical properties of the black coating. It was observed that an optimum thickness of 35 ? 5 lm of electroless nickel is required to achieve the ultra high optical properties after blackening. Energy dispersive X-ray spectroscopy studies suggested that films containing *7% phosphorous are good for further blackening. Scanning electron and optical microscopic studies confirmed that the surface morphology played the major role to get the ultra high optical properties. The environmental tests, namely, humidity, corrosion resistance, thermal cycling, thermo vacuum performance, and thermal stability tests were used to evaluate the space worthiness of the coating. Optical properties of the coating were measured before and after each environmental test to ascertain its stability. The blackened electroless nickel provides higher optical properties in the order of *0.85; this coating has good adhesion, uniformity, and stability in adverse space conditions. Hence, these coatings were extremely suitable for spacecraft thermal control applications.
