A process for treating the surface of magnesium alloy comprises providing a substrate made of magnesium alloy. The substrate is then treated with a chemical conversion treatment agent containing ammonium dihydrogen phosphate and potassium permanganate, to form a chemical conversion film on the substrate. A ceramic coating is then formed on the chemical conversion film using vacuum sputtering.

A process for treating the surface of magnesium alloy comprises providing a substrate made of magnesium alloy. The substrate is then treated with a chemical conversion treatment solution containing cerium nitrate and potassium permanganate as main film forming agents, to form a cerium conversion film on the substrate. A ceramic coating comprising refractory metal compound is next formed on the cerium conversion film by physical vapor deposition.

A stainless steel-and-resin composite includes a stainless steel part and a resin part bonded to the stainless steel part. The stainless steel part has a porous film resulted from anodizing formed thereon. The porous film defines pores with an average diameter of about 100 nm-500 nm. The resin part is integrally bonded to the surface of the stainless steel part having the porous film, with portions of the resin part penetrating in the pores. The resin part mainly comprises crystalline thermoplastic synthetic resin.

A coated article is provided. The coated article includes a substrate, a base layer formed on the substrate; a nickel oxynitride layer formed on the base layer; and a silicon nitride layer formed on the nickel oxynitride layer. The nickel oxynitride layer and silicon nitride layer can protect the substrate from oxidizing at high temperature, which effectively extend the use time of the coated article. A method for making the coated article is also described.

A housing is provided which includes an aluminum or aluminum alloy substrate, an aluminum layer and a corrosion resistant layer formed on the aluminum or aluminum alloy substrate in that order. The corrosion resistant layer is an Al—O layer. Then, La ions are implanted in the Al—O layer by ion implantation process. The atomic percentages of O in the Al—O gradient layer gradually increase from the side of Al—O gradient layer near the aluminum or aluminum alloy substrate to the other side of Al—O gradient layer, away from aluminum or aluminum alloy substrate. Therefore the housing has a high corrosion resistance. A method for making the housing is also provided.

A portable electronic device includes a main body, a flip cover, and a hinge assembly. The flip cover is rotatably fixed on the main body via the hinge assembly. The hinge assembly includes a sensing module, a hinge mechanism, and a microcontroller. The sensing module is configured to detect control signals. The hinge mechanism is configured to control an angle between the flip cover and the main body. The microcontroller is electrically connected to the sensing module. The microcontroller receives the control signals from the sensing module, and controls the hinge mechanism to rotate to a specified angle according to the control signals. The angle between the flip cover and the main body is automatically adjusted correspondingly.
