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.

“…As a result of heat treatment, the characteristics of the deposit can be changed, namely: wear, corrosion and fatigue resistance, hardness, ductility, magnetic properties and other. Maximum hardness can be achieved after a 1-h heat treatment above 360 • C, depending on the phosphorous content [1,2,9]. This has been attributed to fine Ni crystallites and hard intermetallic Ni 3 P particles precipitated during the crystallization of the amorphous phase [9,10].…”

“…The mechanical and tribological properties of these deposits can be further improved by the incorporation of hard particles (SiC, B 4 C, Al 2 O 3 and diamond) [2,3] and dry lubricants (PTFE, MoS 2 and graphite) [1,[3][4][5], resulting in this case in a film with self-lubricating and excellent anti-sticking characteristics.…”

“…EN coatings provide material properties that expand the physical properties beyond those of pure nickel coating systems. These coatings are widely used in the mechanical, chemical and electronic industries because of their corrosion and wear resistance, hardness, lubricity, uniformity of deposit regardless of geometries, solderability and bondability and nonmagnetic properties [1].…”

“…Zhao [11] focused on the effect of the surface-free energy of graded Ni-P-PTFE coatings on bacterial adhesion from the food industrial application angle. Lai-Gui Yu and Zhang [12] studied the tribological properties of Ni-P-PTFE coatings using a ring-on-block machine in the dry condition, at 98 N with rotation speed of 0.09 m/s, and concluded that heat treatment improved the hardness of composite coating and correspondingly enhanced wear resistance. These results had important implications for the industrial applications of Ni-P-PTFE coatings.…”

This aim of this study was to investigate the tribological properties of a self-lubricating Ni-P-polyfluorotetraethylene (PTFE) composite coating prepared by the electroless plating method. The effects of PTFE contents in the coating, load and rotation speed on the tribological behaviors were evaluated using a ring-on-disk wear machine. The results show that there was a distinct decrease in the average value of the friction coefficient from 0.33 to 0.12 at 70 N with an increase in PTFE content from 4.2 to 15.2 wt%. The coating of Ni-P-4.2 wt% PTFE had good antifriction and wear properties at a load of 30-70 N, and that of Ni-P-10.6 wt% PTFE had passable wear resistance and better antifriction at \50 N. Antifriction and wear mechanisms of Ni-P-PTFE are discussed in detail based on the results from micrograph and element analyses of the worn surface, subsurface stratum and wear debris analysis by scanning electronic microscopy (SEM), and energy-dispersive X-ray analysis (EDAX), respectively. The lubricating film (LF) generated during wear played a key role in the antifriction effect, which in turn was dependent on the integrity and thickness of the film determined by the PTFE concentration and wear conditions. The formation, fracture, and delamination course of the LF during wear were also analyzed and characterized.
