Influence of multiple electroless nickel coatings on beech wood: preparation and characterization
Surface modification of beech wood layers was first carried out by rinsing them in distilled water, followed by surface activation with nickel metallic as a catalyst that is prepared on beech wood surface by reduction of Ni+2 ions using as a reduction agent at pH 11. Finally, the nickel was deposited by electroless nickel coating in many baths separated by drying at 100 degrees C during 24 h. Both texture and structural properties of nickel deposited on beech wood were characterized using both scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The SEM results show that the nickel film thickness prepared on beech wood surface after four baths is within 2.9-3 m. The XRD patterns revelated that nickel deposited on beech wood has crystallite size between 83.37 and 149.95 angstrom and the results indicate that the nickel crystallites grow rapidly with increasing number of deposition run.
