摘要： A process for forming a cobalt conversion coating on a metal substrate, thereby imparting corrosion resistance and paint adhesion properties. The invention was developed as a replacement for the prior art chromic acid process. The process includes the steps of: (a) providing a cobalt conversion reaction solution comprising an aqueous, alkaline solution containing a soluble cobalt-III hexacoordinated complex, the concentration of the cobalt-III hexacoordinated complex being from about 0.1 mole per gallon of solution to the saturation limit of the cobalt-III hexacoordinated complex; and (b) contacting the substrate with the aqueous reaction solution for a sufficient amount of time, whereby the cobalt conversion coating is formed. The substrate may be aluminum or aluminum alloy, as well as Cd plating, Zn plating, Zn-Ni plating, and steel. The cobalt-III hexacoordinated complex may be present in the form of [Co(NH.sub.3).sub.6 ]X.sub.3 wherein X is Cl, Br, NO.sub.3, CN, SCN, 1/3PO.sub.4, 1/2SO.sub.4, C.sub.2 H.sub.3 O.sub.2, or 1/2CO.sub.3. (B.) A chemical conversion coating solution for producing a cobalt conversion coating on a metal substrate, the reaction solution comprising an aqueous, alkaline solution containing a soluble cobalt-III hexacoordinated complex, the concentration of the cobalt-III hexacoordinated complex being from about 0.1 mole per gallon of solution to the saturation limit of the cobalt-III hexacoordinated complex. The aqueous reaction solution may be prepared by a bath makeup sequence including the steps of: (a) dissolving an ammonium salt; (b) then dissolving a cobalt-II salt; and (c) then adding ammonium hydroxide (ammonia). (C.) A coated article exhibiting corrosion resistance and paint adhesion properties, the article including: (a) a metal substrate; and (b) a cobalt conversion coating formed on the substrate, the cobalt conversion coating including aluminum oxide Al.sub.2 O.sub.3 as the largest volume percent, and cobalt oxides CoO, Co.sub.3 O.sub.4, and Co.sub.2 O.sub.3.

摘要： A metallic coated steel such as a galvanized sheet is coated with a thin siloxane film having a preferred thickness of about 45 .ANG. for providing temporary corrosion protection. The siloxane film is formed by rinsing the metallic coated sheet with an aqueous solution containing 0.5-2.0 vol. % silane and 0.1-1.0 vol. % crosslinking agent. The silane coating deposited on the rinsed sheet is cured at a temperature less than 200.degree. C. Preferred silane and crosslinking agents are .gamma.-aminopropyltriethoxy and (CH.sub.3 O).sub.3 SiCH.sub.2 CH.sub.2 Si(OCH.sub.3).sub.3 respectively. The siloxane film may be removed by rinsing the metallic coated steel sheet in an alkaline solution prior to coating the sheet with a phosphate conversion coating and a paint.

摘要： The adhesion of plastic encapsulants to electrical leadframes containing substantial amounts of copper is improved by exposing the leadframes to an active oxygen ambient (e.g., 10-30% H.sub.2 O.sub.2) at temperatures below the leadframe annealing temperature (e.g., room temperature to 100.degree. C.) for a few minutes. There is no need to remove the native oxide. A preliminary degreasing step is desirable but not essential. The treatment strengthens any native oxide present on the leadframes without producing an oxide which is so thick as to interfere with subsequent bonding of electronic components or connecting wires to the leadframe. Delamination between the leadframe and the plastic encapsulant by temperture cycling from -65.degree. to 150.degree. C. is substantially reduced.
