Electroless nickel plating process in electrodes for use in oxi-hydrogen reactors

摘要

It was found that when a mixture of hydrogen and oxygen in the fuel gas stream is injected, either gasoline or diesel, it increases its combustion efficiency decreasing at the same time the pollutant emissions of fuels without burning into the atmosphere and saving from 10 up to 30% on fuel. In order to obtain this gaseous mixture, reactors oxyhydrogen operating in conditions in which the engine operates has been developed. A part important of these reactors are the electrodes that should count with characteristics as high resistance to the corrosion, high electronic conductivity and high surface area. This work presents the construction of electrodes for oxyhydrogen reactors with different characteristics, allowing to increase life time while maintaining the efficiency of the reactors. For this electroless nickel plating method was select to deposit a thick coating on aluminum and brass substrates at different bath times. Structural and morphological characterization is presented and discussed. The results obtained by X-ray diffraction and optical microscopy, showed that both materials to favor the deposition of nickel. It can be concluded that the time of deposition of 4, 6 and 8 hours not significantly influences the amount of nickel deposited on the material in reference with X-ray analysis.
