Disclosed are methods of anodizing a metal component. In the methods an anodization bath includes an organic acid.

Mixed acid anodization

A non-destructive inspection method for detecting the presence of a contaminant that has alloyed with a metallic alloy of a part includes exposing the metallic alloy of the part to an extraction solution. The extraction solution extracts at least a portion of any of the contaminant that has alloyed with the metallic alloy. The extraction solution can then be analyzed to determine whether the solution includes any of the contaminant element, which indicates whether the part includes any of the contaminant element.

A new method to determine by quantitative analysis the amount of dye present in dyed engine oils is provided. The method uses imaging techniques, such as spectrophotometry, and a combination of dilution and standard addition techniques to quantitatively determine the concentration of dye in the engine oil to ascertain whether dye concentrations in engine oil have decreased as compared with original specifications, and to quantify the amount of dye to be added to the dyed engine oil to bring dye concentrations to original concentrations.
