The interfacial reactions and joint reliabilities between Sn–9mass%Zn solder and an electroless nickel-immersion gold (ENIG) plated Cu substrate were investigated during reflow and isothermal aging at temperatures between 343 and 423K for aging times of up to 2400 h. After reflowing and aging, the intermetallic compound (IMC) formed at the interface was found to be AuZn3. No Ni-containing react...

NiCu alloy nanowires arrays were embedded into the anodic aluminum oxide (AAO) template by ac-pulse electrodeposition. Different off-time were used in electrolyte with constant concentration of Ni and Cu and acidity of 3. The effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited NiCu alloy nanowires. Atomic forc...

A novel route to fabricate nano-fiber anode material for solid oxide fuel cells (SOFCs) is presented. Firstly, uniform nano-fibers of 8 mol % Yttria Stabilized Zirconia (8YSZ) were formed in an electrospinning process; then, these electrospun fibers were calcined at temperatures up to 1300 °C; and finally the ceramic 8YSZ nano-fibers were coated with nickel in an electroless plating process. Th...

In this work the effects of various methods of agitation on the properties of electroless Ni-P-MoS2 composite coatings were investigated. Magnetic stirring as well as purging the solution with gas (Air, Oxygen, Nitrogen) were used. Plating rate, chemical composition, MoS2 distribution, and hardness of the deposit were measured. Topography of coating was studied with metallography and scanning e...

applying a ni-p electroless coat on the surface of bn(h) particles has a beneficial effect on their wettability in vortex technique during composite manufacturing. in this investigation, different preliminary treatments consisting of different combinations of surface oxidation, sensitization and activation have been investigated. the results obtained from scanning electron microscope (sem) and ...

Nickel foam is widely used as a current lead/current collector and the basis of nickel hydroxide electrodes for various electrochemical devices – batteries, hybrid supercapacitors, electrocatalytic oxidation organic substances. The characteristics commercial samples produced by Novomet-Perm (Russian Federation) obtained electroless then plating Linyi Gelon LIB Co Ltd (China) were studied. natur...

The electroless deposition method was used to prepare Ni-based nanocomposite coatings, this approach represents an alternate way of having coatings on the different substrates. Most previous literatures subject and work deals with a study effect process conditions and, Bath composition microstructure at macroscale Ni-Al2O3 composite coatings. Though, step structure bath are little, present aims...
