ZrO2 7.5Y2O3 4Polymer Powder Description:
ZrO2 7.5Y2O3 4Polymer Powder is specifically engineered to produce high-temperature abradable coatings for clearance control in the turbine sections of aerospace and industrial gas turbine engines. These coatings reduce wear on rotating components and maximize gas path efficiency. They offer excellent thermal stability at high temperatures, superior thermal shock resistance, and sufficient erosion resistance while providing outstanding abradability. The zirconia matrix, stabilized with yttria, improves the thermal cycle life at high temperatures, while the added polymer introduces beneficial porosity that reduces thermal conductivity, enhances sintering resistance, and increases abradability when cut by cubic boron nitride (cBN) or silicon carbide-tipped blades. ZrO2 7.5Y2O3 4Polymer Powder coatings deliver excellent erosion resistance, making them perfect for challenging turbine applications.
