“…Figure 9 shows the dependence of the hardness and elastic modulus of 316L coatings obtained by nanoindentation. Hardness and elastic modulus follow the same trend for 316L coating sprayed with He and N 2 , which agrees with the literatures [47][48][49][50].…”

In this study, simulation and experimental methods were used to investigate the influence of cold spray conditions on AISI 316L stainless steel coatings. The effect of both helium and nitrogen gases used was investigated. The temperature, particle sizes of spraying powder, and distance from the nozzle throat to the impinging point were estimated by using the Kinetics Spray Solutions GmbH software. The 316L stainless steel (SS) coatings were examined by X-ray diffraction, Scanning Electron Microscopy and Energy Dispersive X-Ray Microanalysis. The tribological behavior was evaluated under different loads (2 N and 5 N) in dry conditions. It was found that the nitrogen and helium propellant gas with high speed and fine particles led to produce good coatings with dense microstructures. From the nanoindentation experiments, the Young's modulus and hardness of the SS 316L samples were enhanced of about 8% with helium due to the high particle velocity. It was shown that the wear resistance of SS 316L produced with helium was higher than that of the standard SS 316L coatings. The coatings produced with helium revealed lower friction coefficient (0.65) and wear rate (6.9 × 10–4 mm3/Nm) under 2 N applied load than that obtained nitrogen. It was also found that the SS 316L cold sprayed by helium with dense structure presents high hardness and good tribological performance that can be suggested for several applications.

“…Nickel can be deposited via conventional EL ( vide infra ) and galvanic ,,,− methods, though in the latter case Ni more often functions as a sacrificial substrate for replacement by other metals than the deposited metal. ,,,,− Conventional EL Ni depositions utilize baths containing H 2 PO 2 – , − amine boranes, ,− BH 4 – , − or to a lesser extent, N 2 H 4 , − as reducing agents. Baths containing H 2 PO 2 – deposit the metal as NiP alloys, whereas those containing amine boranes or BH 4 – yield NiB alloys and those containing N 2 H 4 deposit Ni metal.…”

The electroless plating of metals and their alloys, oxides, and chalcogenides represents a critically important technology for the automotive, aerospace, machine tools, and, especially, the electronics industries. Since the initial efforts involving the plating of industrially important metals, such as Ni, Co, Cu, Ag, and Au, in the mid-20th century, the process has evolved to encompass a growing number of elements. At the same time, this expansion in the palette of accessible metals has enabled progress in these industries and evoked new nonconventional applications. In this review, we collect and survey available electroless processes in aqueous and organic solvent systems for each element organized according to position in the Periodic Table as a resource for the reader. Examples illustrating progress in the field are presented and are described in sufficient detail to be useful and understandable for both the expert and nonexpert. Given the historical importance of electronics as a driver for development of electroless processes, examples are electronics-related where possible. However, we strive to also include examples of applications in nontraditional fields to provide the reader with a sense of generality available for electroless methods. The review closes with an outlook for the field and a challenge to scientists and engineers to adapt electroless processes for new applications to continue the growth of the field.

“…Among electrodeposition, the most popular coatings are Ni-based coatings. In addition Ni element, it is also possible to carry out binary or ternary alloy coatings with the reinforcement of alloying elements such as P, Mo, W, and B [6][7][8][9]. It is possible to produce high performance Ni-Watt (Ni-W) coatings, especially with reinforcing elements such as tungsten, with superior mechanical and physical properties and high melting temperatures.…”

The Ni-W/PTFE co-depositions were successfully prepared on steel via pulse electrodeposition methods. Electrodeposition was perform by dispersing 5-20 g/L PTFE particles from Ni-Watt bath. The surface morphology, phase analyses crstalytallite size, distorsion and hardness of the samples were characterized by SEM, XRD, and Vicker?s microhardness tester. The friction coefficient of the coatings were carried out using CSM microtester. As increasing with the concentration of the PTFE in the solution, the wear resistance properties of theco-depositions were increased. These experimental results determined that the PTFE concentration of 15 g/L in the electrolyte was the optimum content to obtain the best micro-structure and wear performance.
