One-dimensional carbon nanotubes and two-dimensional graphene nanosheets with unique electrical, mechanical and thermal properties are attractive reinforcements for fabricating light weight, high strength and high performance metal-matrix composites. Rapid advances of nanotechnology in recent years enable the development of advanced metal matrix nanocomposites for structural engineering and functional device applications. This review focuses on the recent development in the synthesis, property characterization and application of aluminum, magnesium, and transition metal-based composites reinforced with carbon nanotubes and graphene nanosheets. These include processing strategies of carbonaceous nanomaterials and their composites, mechanical and tribological responses, corrosion, electrical and thermal properties as well as hydrogen storage and electrocatalytic behaviors. The effects of nanomaterial dispersion in the metal matrix and the formation of interfacial precipitates on these properties are also addressed. Particular attention is paid to the fundamentals and the structure–property relationships of such novel nanocomposites.

Tribology of electroless nickel coatings – A review

Arc discharge synthesis of carbon nanotubes: Comprehensive review

This review outlines the development of electroless Ni–P composite coatings. It highlights the method of formation, mechanism of particle incorporation, factors influencing particle incorporation, effect of particle incorporation on the structure, hardness, friction, wear and abrasion resistance, corrosion resistance, high temperature oxidation resistance of electroless Ni–P composite coatings as well as their applications. The improvement in surface properties offered by such composite coatings will have a significant impact on numerous industrial applications and in the future they will secure a more prominent place in the surface engineering of metals and alloys.

Electroless Ni-P composite coatings

Studies on crystallization of electroless NiP deposits

A study on the wear resistance of electroless Ni–P/Diamond composite coatings

Electroless nickel (EN) coating is a well established surface engineering process that involves deposition of a metal–metalloid alloy coating on various substrates. The effect of surfactants on the surface roughness, microhardness and microstructure of electroless Nickel–Phosphorus (EN) surface protective coating obtained from an alkaline bath is presented in this paper. In this study the influence of surfactants sodium dodecylsulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB) on the surface roughness, microhardness and microstructure of coated samples are investigated. EN deposits with addition of surfactant SDS and CTAB at a concentration of 0.6 g/l produce a smooth surface and the average roughness value (Ra) is 1.715 µm for SDS and 1.607 µm for CTAB which is less than the Ra value of EN deposit without surfactant addition (1.885 µm). The mean average roughness value (Ra) with addition of surfactant is 1.796 µm. It was found that without surfactant the micro hardness value of as-coated condition was 450 Hv. The micro hardness value increased to 685 Hv with addition of SDS and 675 Hv with addition of CTAB. The complete experimental details, results obtained and their analysis is presented in this paper.
