Composite polymer derived ceramic system for oxidizing environments

Mechanical properties of polymer-derived ceramic composite coatings on steel

“…Previous work has identified a suitable polymer-expansion agent system, optimized processing parameters, and characterized the compositional and microstructural evolution of the coatings as a function of pyrolysis temperature. [7][8][9] This paper will focus on the mechanical characterization of these coatings including hardness, elastic modulus, ultimate tensile strength, and interfacial shear strength.…”

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).…”

“…In order to make thick coatings, the polymeric systems have been filled with reactive fillers that expand during the polymer-to-ceramic conversion (Torrey et al 2006;Torrey and Bordia 2007;Wang et al 2011Wang et al , 2014. These coatings have been shown to demonstrably improve the oxidation resistance of both Fe-based and Ni-based superalloys.…”

Computer Aided Multi-scale Design of SiC-Si3N4 Nanoceramic Composites for High-Temperature Structural Applications

“…The Si-C-O ceramic coatings were made using polymer-precursor processing. This method is a novel way to process low dimensional ceramics such as fibers and coatings, sometimes collectively referred to as the polymer-derived ceramics (PDCs The Si-C-O ceramic coatings investigated in this research were made using processing methods based on polymer-precursors by Prof. Raj Bordia's group at the University of Washington, Seattle-WA, [152][153][154][155]. The coating thickness is approximately 15 µm.…”
