BryCoat CVD Titanium Carbide (TiC) Coatings
BryCoat CVD Coatings, featuring uniform Titanium Carbide (TiC) coating of precision bearing balls are used to improve performance in high value instrument bearing appliions. BryCoat uses a specialized CVD process developed by CSEM of Neuchâtel Switzerland to deposit ultra-hard ceramic material uniformly onto bearing balls.
In situ characterization of foreign object damage (FOD) in …
In the current work, the real‐time FOD behavior of a mullite/ silicon EBC was visualized via a dynamic synchrotron X‐ray source in phase contrast imaging (PCI) configuration. Prior to the in situ FOD experiments, the microstructure and composition of the coating were, respectively, characterized using a scanning electron microscope (SEM) and X‐ray diffraction (XRD).

Reaction-sintered silicon carbide: newly developed …
Newly developed high-strength reaction-sintered silicon carbide is an attractive material for lightweight optical mirror with two times higher bending strength than other SiC materials. The polished surface has no pore and is suited to visible region as well as infrared without CVD SiC coating.
HVOF Sprayed WC-Co, WC-Co-Cr Coatings
Thermal Spray Coatings of WC-Co and WC-Co-Cr Thermal spray coating is a surface modifiion process where molten or softened particles are applied by impact onto a surface such as stainless steel. High Velocity Oxy-Fuel (HVOF) Tungsten Carbide Cobalt (WC-Co) coatings produce extremely dense, near zero porosity and wear resistant surfaces.
SIGRAFINE® SiC Coating | SGL Carbon
Silicon carbide is deposited as thin layers on carbon fiber-reinforced carbon by CVD (chemical vapor deposition). Deposition takes typically place at temperatures of 1,200-1,300 °C. The thermal expansion behavior of the substrate material should be adapted to the SiC coating to minimize thermal stresses.
HTCVD Guarantees High Quality Silicon Carbide for …
