The treatment agent includes components (A), (B), (C), and (D). The component (B) is contained in an amount of 50 to 150 parts by mass on a SiO2 solid basis, and the component (C) is contained in an amount of 5.0 parts by mass or more on an elemental metal basis, the amounts being based on 100 parts by mass, on a solid basis, of the component (A). The component (D) is contained in an amount that a molar ratio of M2+ and M3+, each being a metal element in the treatment agent for chromium-free insulating coating formation, to a phosphorus element P satisfies a specified relationship, and the treatment agent for chromium-free insulating coating formation has a pH of less than 4.5.

Abstract: The present invention provides a surface treatment method for magnesium alloy object, the method comprising: providing a magnesium alloy object; preprocessing the magnesium alloy object; performing micro-arc oxidation (MAO) treatment on the magnesium alloy object to form a micro-arc oxidation layer; Sputtering at least one metal layer or at least one non-metal layer on a surface of the micro-arc oxidation layer, the metal layer or non-metal layer which is sputtered on the micro-arc oxidation layer has different angles by using surface roughness of the micro-arc oxidation layer when a light source is projected on the metal layer or non-metal layer; and Sputtering a paint layer on the metal layer or non-metal layer to make the surface metallic lustrous and corrosion-resistant. The present invention further provides a surface structure of a magnesium alloy object.

Abstract: Methods of obtaining a titanium dioxide nanofilm or microfilm are provided herein. A pure sheet of titanium is irradiated with a CO2 laser to produce the titanium dioxide nanofilm or microfilm. The titanium sheet can optionally be doped with an oxide, such as barium oxide. The method produces titanium dioxide nanofilms or microfilms that can be produced in more than one phase, such as a rutile phase, an anatase phase, or both combined. The titanium dioxide nanofilms or microfilms can be directly fabricated with high purity without any further processing.

Abstract: Methods of patterning semiconductor devices comprising selective deposition methods are described. A blocking layer is deposited on a metal surface of a semiconductor device before deposition of a dielectric material on a dielectric surface. Methods include exposing a substrate surface including a metal surface and a dielectric surface to a heterocyclic reactant comprising a headgroup and a tailgroup in a processing chamber and selectively depositing the heterocyclic reactant on the metal surface to form a passivation layer, wherein the heterocyclic headgroup selectively reacts and binds to the metal surface.
