ni-p and ni layers multilayer coatings were applied to az31 magnesium alloy utilizing electroless and electrodeposition procedures. the aim of the project was to decrease cracks and increase corrosion resistance of the coatings. in order to compare the coatings, the effect of single layer electroless ni-p coatings with different thicknesses was also investigated. the microstructure and phase co...

Abstract In this paper, the pressing and sintering properties of three kinds copper-coated chromium composite powder copper-chromium mechanical mixed with same copper content were compared studied. The was prepared by a diffusion method, liquid electroless plating method an added binder. results show that increase in content, advantage copper-clad is more obvious. density, hardness, size shrink...

In this study, a novel multi-walled carbon nanotubes reinforced nanocrystalline copper matrix composite with super high strength and moderate plasticity was synthesized. We successfully overcome the agglomeration problem of the carbon nanotubes and the grain growth problem of the nanocrystalline copper matrix by combined use of the electroless deposition and spark plasma sintering methods. The ...

Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal e...

In this work, composite Ni–P-multiwalled carbon nanotube films were produced by electroless deposition. The main goal was to investigate the influence of multiwalled loading on local electrochemical behavior films, as probed scanning microscopy (SECM). coatings also characterized with respect their crystalline structure, surface, and cross-section morphologies. Adhesion strength examined scratc...

We have employed electroless deposition to prepare smooth films (mirrors) of silver that could be used as substrates in microcontact printing (μCP) of alkanethiols. Good-quality SAMs of hexadecanethiolate were formed on thin films of electroless silver by printing with an elastomeric stamp; these SAMs were effective resists in protecting the underlying silver from etching in an aqueous ferricya...

The electroless coating technique is one of the elegant methods available for the production of protective coatings on surface. Our study has been aimed at the conditions of the electroless deposition of copper coating onto the iron powder particles from sulphate electrolyte. The course of the electroless process depends on the composition and pH of the electrolyte as well as on the size and co...
