A rust inhibiting process for cleaning and protecting a target object is disclosed. Comprising mixing at least a rust inhibitor and a fluid into a slurry mixture, spraying the slurry mixture at the target object from within a reservoir of a slurry blasting system, separating a tarnished top layer and a parent metal of the target object with a slurry stream, cleaning the parent metal with the rust inhibitor, preventing the parent metal from impregnating with contaminants during cleaning with the rust inhibitor, and protecting the parent metal with the rust inhibitor after spraying is complete. The slurry stream comprises the slurry mixture of the slurry blasting system being sprayed with the slurry blasting system. The slurry blasting system comprises a tank.

A method of cleaning a component includes providing the component following the operation of the component in a high temperature environment, the component including a thermal barrier coating (TBC), cleaning the TBC of the component using a sponge jet blasting process, and measuring a cleaned thickness of the TBC to verify that the cleaned thickness exceeds a predetermined minimum value that will allow the return of the component to the high temperature environment.

A method for conditioning ceramic coating on a part for use in a plasma processing chamber is provided. The ceramic coating is wetted with a solution, wherein the solution is formed by mixing a solvent with an electrolyte, wherein from 1% to 10% of the electrolyte dissociates in the solution. The ceramic coating is blasted with particles. The ceramic coating is rinsed.
