Stainless steel has been used for years as a commodity in the most different fields of industry due to its excellent physical and chemical resistance properties, however highly undesired energy expenditure on the forced abrasion of fluids to the steel wall is caused due the material''s rough surface and friction. Silazane polymer-derived ceramic coatings may be a promising alternative to this problem by modifying the substrate surface and wettability. Thereafter, AISI 304 steel samples were dip-coated in HTT 1800 solutions and treated thermally at temperatures ranging from 200-700 oC in order to evaluate the coating thermal resistance and interaction to different liquids. Fillers were also as to tailor greatly the interaction with liquids at high temperatures (400-500 oC). In comparison to the raw substrate, the coated samples exhibited a more oleophobic and more hydrophilic behavior. TGA analysis detected a mass loss of about only 20% for the pure coating material at 1000 oC.
