“…10,11 Also, using suitable surfactants greatly affects the uniform distribution of particles in the composite coatings. 12,13 In recent years, several investigations have been performed on hard and soft particles such as ceramics and polymers, 14–18 but there is a few information about the hardening mechanisms of composite coatings. Alumina as a common hard material with significant properties has been paid more attention among other hard particles in electroless composite coatings.…”

In this article, alumina nanoparticles were co-deposited within Ni–P electroless coating on mild steel samples and then isothermal heat treatment was done at 400℃ for 1 h. The size distribution of nanoparticles was evaluated by transmission electron microscopy and the concentration of alumina reinforcements in Ni–P matrix was determined using field emission scanning electron microscopy and image analysis software. The phase transformation of coatings was analysed by X-ray diffraction and differential thermal analysis. Also, mechanical properties of coatings were evaluated by microhardness and indentation tests. The results showed that mechanical properties of Ni–P–Al2O3 nanocomposite coatings strongly influences by dispersion and/or precipitation hardening mechanisms.

“…66 This result interestingly correlates well with the findings from our previous work where with the introduction of 0.9 g L −1 SDS, up to 60% by volume, yttria stabilized zirconia (YSZ) was incorporated into the nickel matrix. 83 Zhou and co-workers also found that 50 mg L −1 of anionic surfactants SDBS and SDS, and 100 mg L −1 of the surfactant triethanolamine, yielded good results during the codeposition of nano Al 2 O 3 particulate matter. 22 Three different types of flourosurfactants were utilized by Amell et al 67 during the codeposition of SiC and Si 3 N 4 particles.…”

The effects of surfactants on the dynamics and characteristics of plain and composite electroless nickel plating (ENP) are highlighted and discussed herein. An outline of the rudiments of surfactants and some underlying selection criteria is presented at the outset, before emphasis is laid on the salient benefits of introducing such external agents during the plating process. Evidence suggests that their influence on key coating characteristics such as the rate of deposition, structure, corrosion resistance, and the degree of second-phase particle incorporation into the nickel matrix is significant, and depending on the nature and concentration of surfactant employed, can be of immense value to the system.

“…Nwosu et al (16) conclusively found that as long as the SDS surfactants critical micelle concentration had been exceeded, the ceramic content of a co-deposited nickel / YSZ electrode had a direct relationship with the surfactants concentration in the bath. Local concentrations of ceramic to nickel ratios as high as 60 volume % were achieved.…”

Manufacture of Solid Oxide Fuel Cells Using Electroless Co-Deposition: A Review of Work Carried out at Edinburgh Napier University

2015

This paper reviews work carried out at Edinburgh Napier University on the manufacture of anodes and cathodes for solid oxide fuel cells (SOFCs) using electroless co-deposition of nickel and ceramic powders. Most of the work has been focused on anodes where the co-deposition of nickel and yttria stabilised zirconia (YSZ) negates the need for traditional manufacturing methods such as screen printing and removes the need for expensive and time consuming high temperature consolidation of the ceramic part of the composite. Work has also been carried out manufacturing cathodes by electroless co-deposition replacing YSZ with lanthanum strontium manganite and lanthanum nickel ferrite. Anodes and cathodes of both planar and tubular designs of SOFCs have been successfully manufactured using this technique and process variables have included ceramic particle size, bath pH, ceramic loading, the inclusion of pore-formers and tubular orientation in the electroless bath. Testing of the electrodes included impedance analysis, long term degradation testing at 850 o C for 500 and 1000-hours, high temperature electrical conductivity measurements, scanning electron microscopy and energy dispersive X-ray analysis. The cost benefits of the electroless codeposition process compared with other conventional processes are also discussed.
