A coated article includes a substrate, an anti-corrosion layer formed on the substrate, and a decorative layer formed on the anti-corrosion layer. The substrate is made of magnesium or magnesium alloy. The anti-corrosion layer includes a magnesium layer formed on the substrate and a magnesium oxide layer formed on the magnesium layer. The coated article has improved corrosion resistance.
摘要:
A coated article includes a metal layer coated on a substrate. The substrate is made of plastic with photosensitivity property, and has a plurality of free radicals —O. and —CO. a surface thereof. The metal layer is coated on the substrate. The free radicals link with metal atoms of the metal layer to connect the substrate and the metal layer.
摘要:
A process for joining a carbon steel part and a silicon carbide ceramic part, comprising steps of: providing a carbon steel part, a SiC ceramic part, and a Ni foil; bringing surfaces of the carbon steel part, SiC ceramic part, and Ni foil into contact, with the Ni foil inserted between the carbon steel part and SiC ceramic part; applying a pulsed electric current to the parts to be joined, heating the parts to a joining temperature of about 800-1100° C., and simultaneously applying a joining pressure of about 20-60 MPa to the parts while the current is applied, and maintaining the joining temperature and the joining pressure for about 10-30 minutes.
摘要:
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.
