[Abstract]:Rice husk based ceramic particle (RHC) is one of the effective ways to realize the comprehensive utilization of rice husk. The conventional Electroless plating method can expand the application range of rice husk based ceramic particles. The optimum technological parameters of nickel plating were determined by single factor and orthogonal experiments. The effect of adding nickel-coated rice shell based ceramic particles on the antiwear and antifriction properties of the composites was studied by adding nickel-coated rice shell based ceramic particles to aluminum-based materials. The surface of nickel-plated rice shell based ceramic particles was analyzed by X-ray diffractometer and high resolution transmission electron microscope. The results showed that the optimum conditions of nickel plating on the surface of rice husk based ceramic particles were as follows: temperature 60 鈩，
