Latest Patents
One of Isao Yuri's latest inventions is an apparatus for measuring corrosion loss. This innovative device allows for the quantitative determination of corrosion loss characteristics in ceramic and heat-resistant metallic materials. It is designed to be safe, cost-effective, and easy to operate, with a compact size. The apparatus continuously feeds an atmosphere gas into a test-piece-placing section, which accommodates a material test piece. The gas is heated to a predetermined temperature, and the design includes a gas-heating section and a test-piece-placing section made from a single ceramic tube. The cross-sectional area of the gas-heating section is larger than that of the test-piece-placing section, enhancing its functionality.
Another significant patent is for corrosion-resistant silicon nitride ceramics. This invention features a layered structure that includes an adhesion enhancing layer, a stress-relaxing layer, and a crack extension preventing layer, all laminated on a silicon nitride substrate. Additionally, a surface corrosion-resistant layer made mainly of zirconium oxide is included. The thermal expansion coefficients of the various layers are carefully designed to meet specific relational expressions, ensuring optimal performance.
