Corrosion inhibiting properties in surface coating compositions are increased by admixing a sol or gel containing salt with a polymer and usually a surface coating paste stock. A novel surface coating composition containing a polymer and salt homogenously distributed in the composition is prepared from the sol or gel and has increased corrosion-inhibiting properties compared to a composition without the admixed sol or gel.

A method of manufacturing a ceramic insulated wire involves preparing an extrudable gel compound formed by dissolving a metal-organic compound in a solvent and adding at least one thermoplastic polymer or its monomer to the mixture to make the gel compound extrudable. The so prepared extrudable gel compound is then extruded around the outer periphery of a conductor for coating the conductor with a gel coating. Thereafter a heat treatment is performed for sintering the gel compound to form a ceramic coating.
The invention relates to a corrosion-inhibiting material comprising a composite containing a metal oxide gel, where necessary modified by an organic polymer, and one or more corrosion inhibitors, and to a method for the production thereof. The corrosion-inhibiting composite material is used for producing corrosion-protective packaging material, for coating metallic and metallized articles as well as for corrosion protection in confined environments.
A colloidal suspension has a metal core surrounded by a surfactant. The colloidal suspension is about 0.5 micron to about 3-4 microns in diameter. The colloidal suspension acts as a lubricant and protects surfaces in rolling and/or sliding contact. When mixed with a lubricant, the colloidal suspension increases the operating life of the lubricated item. The colloidal suspension preferably is tin or bismuth nano-phase particles encased in a surfactant, preferably oleyl sarcosinate, N-coco sarcosinate, sodium sulfonate, petroleum sulfonate, or octadecenyl amine.
A method for forming a wirebond connection to an integrated circuit structure includes forming an insulative structure overlaying a corrosion susceptible metal wiring within the integrated circuit structure, defining a via through the insulative structure above a portion of the corrosion susceptible metal without exposing the portion of the corrosion susceptible metal, and attaching a wirebond material to the portion of the corrosion susceptible metal. The attaching process includes a preliminary process of exposing the portion of the corrosion susceptible metal. The attaching completely covers the portion of the corrosion susceptible metal.
