Nano-SiC effect on wood electroless Ni–P composite coatings

Abstract

In this research, Ni-P/nano-SiC composite coatings were prepared on wood surface by simple electroless plating approach. The flatness, porosity, and crystallinity of Ni-P/nano-SiC composite coatings were investigated. The flatness and porosity of the composite coatings enhanced with the increase in nano-SiC content of the coatings, and the composite coatings were obtained within the range of 0.5-1.5 g (1.8 g/L) nano-SiC in the solution bath. The full width at half maximum values of Ni X-ray diffraction peaks in the composite coatings broadened and strengthened with the increment of nano-SiC content in the coatings, which triggered preferred growth direction of diffraction peaks. The composite structure was characterized with scanning electron microscopy images. The uniformity of particles in the composite coatings could be improved obviously with the increase in the nano-SiC content of the coatings because an amorphous phase of SiC hindered the movement of dislocations and declined the size of NiP crystallite. Besides, the flatness, porosity, and crystallinity of composite coatings depended on the P content in the composite coatings. P content can be decreased by increasing SiC content of plating solutions. The flatness, porosity, crystallinity, and wear resistance of composite coatings exhibited excellent properties as the content of nano-SiC in the composite coatings reached 1.0 g (1.8 g/L).

Properties of Pinus modified with silicon–titanium binary oxides

“…With the development and utilization of natural resources and the emergence of novel materials, functional wood has received increasing attention. Modification technologies have recently been used to improve wood properties such as magnetism Pan et al 2015;Guo 2017;Lou et al 2017;Muff et al 2018), photocatalysis (Mo et al 2012;Li et al 2015;Lin et al 2015;Rao et al 2016;Dong et al 2017;Chang et al 2018), and aging resistance (Guo et al 2016;Li et al 2018), among others (Liu et al 2013;Guo et al 2015;Zhang et al 2015;Huang et al 2016). To summarize, there are many methods of inorganic modification of wood, but there are some drawbacks.…”

Preparation and characterization of micro or nano cellulose fibers via electroless Ni-P composite coatings

“…Nowadays, the industrial applications of wood electroless Ni-P were mainly used in the preparation of wood electromagnetic shielding material because the shielding materials of wood electroless Ni-P as the substrate material were not only low cost-effective and lightweight but also easy to manufacture; furthermore, the shielding effectiveness nearly reached 70 dB, expecting that the electromagnetic shielding material of wood electroless Ni-P would have broad prospects. 13 There were no reports focusing on the hollow magnetic materials based on micro or nano cellulose fibers via electroless Ni-P. This method is simple and easy to prepare hollow magnetic materials.…”
