High performance environmental barrier coatings, Part I: Passive filler loaded SiCN system for 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.…”

The Conversion of Perhydropolysilazane into SiON Films Characterized by X‐Ray Photoelectron Spectroscopy

“…To make them, typical methods include PECVD, PVD, and sputtering . Recently, it has been shown that thin ceramic films can be made via a simpler polymer‐derived ceramic route . This opens up a range of possibilities for cost‐effective and innovative processing of the materials.…”

Ceramics for Sustainable Energy Technologies with a Focus on Polymer-Derived Ceramics

“…Both filled and unfilled coatings have been used for applications ranging from environmental protection to wear resistance (Torrey et al 2006;Torrey and Bordia 2008a, b;Wang et al 2014;Günthner et al 2011;Wang et al 2011). Joining and sealing of ceramic materials has also been achieved using preceramic polymers (Colombo et al 2000;Lewinsohn et al 2005).…”
