Advanced coatings on the basis of Si(C)N precursors for protection of steel against oxidation

Corrosion and Oxidation Behavior of Polymer Derived Ceramic Coatings With Passive Glass Fillers on Aisi441 Stainless Steel

“…They are also specific by low temperature processing and the potential to tailor the properties via microstructure and composition design. Polymer derived ceramic (PDC) composite coatings are promising candidates to be used as alternative environmental barrier coatings for corrosion and oxidation protection of metals [12]. A new approach based on development of oxidation resistant PDC coating systems through pyrolysis of suitable predominantly silicon containing precursors such as polysiloxanes [13], polycarbosilanes [14] or polysilazanes [15,16,17], which could act as a diffusion barrier to oxygen was reported.…”

Planar, Polysilazane‐Derived Porous Ceramic Supports for Membrane and Catalysis Applications

“…In addition to significantly lowered consolidation temperatures as well as the ability to produce high‐purity products, a major advantage of this route is the wide variety of shaping options, including the ability to produce coatings, fibers, tapes, and tubes . Due to the polymer nature of precursors, a number of processing methods are available which are not accessible by resorting to conventional powder‐based ceramics.…”

Self-assembled microstructured polymeric and ceramic surfaces

“…Oxide, non-oxide or metallic/intermetallic filler powders may be used for shrinkage compensation. 8 Most of the preceramic polymer coatings are based on polycarbosilanes, 9,10 polysilazanes, [11][12][13] or polysiloxanes, [14][15][16] and they are applied by spin or dip coating.…”
