Mechanical properties of polymer-derived ceramic composite coatings on steel

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

“…Key issue to produce defect free coatings is the reduction of shrinkage and porosity formation by adding passive or active fillers [21], which partially or completely eliminates the volume change due to polymer to ceramic conversion. A number of authors figured out that the incorporation of passive fillers like BN [22], ZrO 2 [23] or Al 2 O 3 [24] can decrease the volume fraction of shrinking while reactive filler particles like ZrSi 2 [25] or TiSi 2 [26,27] can compensate the shrinkage of pre-ceramic polymers through reactions with the polymer decomposition products and formation of products with higher specific volume. Furthermore, depending on the properties of the substrate, the thermal expansion coefficient of the coatings can be adjusted by an adequate filler material.…”

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.…”

Giant piezoresistivity of polymer-derived ceramics at high temperatures

“…[3][4][5] It has been shown that PDCs remain stable up to 1400-1500 • C and, in special cases, even at 2000 • C. 6 The PDCs have been shown to hold promise for high temperature membranes, oxidation resistant coatings, and flux sensors for gas turbine engines. [7][8][9] In addition to their structural properties and chemical stability, the PDCs also possess functional properties of different kinds. They are semiconductors at least up to 1300 • C. 10 Though amorphous, they are intensely photoluminescent 11 with a wide spectrum emission.…”
