Abstract: An aluminum article includes a substrate made of aluminum or aluminum alloy, a porous aluminum oxide layer formed on the substrate, and a transparent vacuum coated layer formed on the aluminum oxide layer. The aluminum oxide layer has a top surface and a plurality of pores defined therein. The pores run through the top surface and each pore is formed by peripheral wall and bottom wall. The vacuum coated layer covers the top surface as well as the peripheral walls and bottom walls of the pores, thereby forming a profile corresponding to the aluminum oxide layer.

Abstract: A method for manufacturing a composite of metal and resin includes steps of: providing a metal piece; cleaning the metal piece in a degreasing agent solution; partially shielding the metal piece and remaining portions of the metal surface uncovered; blasting the metal piece with hard particles to form a plurality of micro pores in the uncovered portion; inserting the metal piece into a mold; injecting molten resin material on the metal piece, the resin material combined with the metal piece when the resin material is cool.

Abstract: A method for manufacturing a composite of metal and resin including following steps: providing a metal piece; cleaning the metal piece in a degreasing agent solution; etching the surface of the metal piece by focused ion beam to form a pattern of nanopores; inserting the metal piece into a mold and heating the metal piece to reach a temperature in a range of 100° C. to 350° C.; and injecting molten resin material on the metal piece. The resin material is combined with the metal piece when the resin material is cool.

Abstract: A surface hardened substrate includes a base, a transition layer disposed on a surface of the base, and a hard layer disposed on the transition layer. The transition layer includes at least two kinds of transition metals. The hard layer includes an alloy and a nonmetal. The alloy includes the at least two kinds of transition metals.
