Abstract

Several DSA® coatings were prepared by thermal decomposition of metallic chloride salts on titanium base. It was shown that the painting composition does not necessarily correspond to the final coating composition. Thermogravimetric and fluorescent X-ray measurements were used to identify and characterize the material losses. It was found that IrO2, Ta2O5 and RuO2 compounds can be deposited with almost 100% yield, while SnO2 and Pt precursors give high material losses. The influence of parameters affecting the deposition yield are discussed.
