Latest Patents

Watanabe's latest patents focus on a method for producing a ceramic-coated blade of a gas turbine. This method effectively prevents the thickening of an Al₂O₃ layer at the interface between the ceramic layer and the primary layer. By utilizing a powder of MCrAlY alloy, specifically Co-32% Ni-21% Cr-8% Al-0.5% Y, a primary layer is formed on a substrate made of a heat-resistant Ni base alloy, Rene'-80. Additionally, a heat-resistant ceramic layer is created using a mixture of ion-conductive ZrO₂-8 wt. % Y₂O₃ ceramic and insulative ceramic, such as Al₂O₃. This innovative mixture can exhibit either a columnar structure or a porous structure, enhancing the blade's performance.
