Latest Patents

Eoin Joseph Barry holds a patent for "Inert calcia facecoats for investment casting of titanium." This patent describes a calcia mold facecoat that is applied to molds used for casting parts composed of reactive metals. The facecoat consists of a calcium carbonate-based slurry, which includes a dense grain calcium carbonate powder and an aqueous-based binder. This innovative solution is applied to a wax or plastic pattern utilized in the lost wax process for fabricating a casting shell. The mold is constructed using multiple dips of alumina-silicate slurries and is subsequently fired at high temperatures in an oxygen-rich environment. The metal part is cast before the fired mold cools below approximately 800°C. Notably, organometallic-based slurry binders are avoided, resulting in significant cost savings due to the environmentally benign nature of the aqueous-based suspensions.
