Abstract: A composite article includes an inorganic non-metallic article, a resin article, and a connecting layer located between the inorganic non-metallic article and the resin article. The connecting layer is configured to connect the inorganic non-metallic article and the resin article together. A surface of the connecting layer connected with the resin article includes a plurality of microstructures, a portion of the resin article fills in the plurality of microstructures. A method for making the composite article is also provided.

Abstract: A composite article includes an inorganic non-metallic article and a resin article. The resin article is connected to the inorganic non-metallic article. The inorganic non-metallic article includes at least one connecting surface. At least a portion of the connecting surface comprises groove-peak like microstructures. At least one of the microstructures comprises a rough and/or porous surface having at least one of a roughness element and a porous structure. The inorganic non-metallic article and resin article are combined together through the microstructures. A method for making the composite article is also provided.

Abstract: A housing includes a ceramic layer for decoration, an intermediate layer formed on at least one surface of the ceramic layer, and a substrate coupled on the intermediate layer. The surface of the intermediate layer coupled to the substrate is rough and/or porous for improving the bonding of the substrate to the intermediate layer.
