Abstract: Process for providing a protective coating to a metal surface by applying a nickel or tantalum plate layer to the surface and dispersing particles of a hard material such as diamond, alumina, vanadium nitride, tantalum carbide and/or tungsten carbide within the nickel or tantalum plate layer as the plating is occurring.

Abstract: An in-situ method for repairing a thermal barrier coating deposited on a component that has suffered localized spallation including depositing a ceramic paste on a surface area of the component exposed by the localized spallation, the ceramic paste including a ceramic material in a binder material, the ceramic material including solid zirconia particles, the binder material including a silicone compound. The method also including heating the binder material to yield a repair coating that covers the surface area of the component, the silicone compound promoting the bonding of the solid zirconia particles.

Abstract: A method for forming a monitoring deposit on a substrate comprises determining a temperature range to subject the substrate to provide a high temperature of operation up to less than a critical substrate deterioration temperature; selecting a binder to monitor temperature by emitting an indicator within the determined temperature range; combining the indicator and the binder; and applying the combined indicator and binder to the substrate to form the monitoring deposit. An article comprises a substrate; and a combined indicator and binder applied into the substrate, wherein the binder emits the indicator within a temperature range determined to subject the substrate to high temperature operation up to less than a critical substrate deterioration temperature.
