Innovnano, an expert manufacturer of high performance ceramic powder, has produced highly pure 4YSZ (4 mol% yttria stabilised zirconia), a thermal barrier coating material with exceptional properties for withstanding extreme temperature variations found in demanding operating environments. Innovnano’s 4YSZ has a major application within turbine engines, especially in the aerospace industry. Due to its low thermal conductivity only a very thin coating is necessary for impact, thereby ensuring that the component weight of the rotating turbines is kept to a minimum.
With a melting point of 2,700°C and hardness of 14GPa, Innovnano’s 4YSZ is the ideal topcoat thermal barrier. It has been shown by CPT, an independent centre for thermal spray technology (University of Barcelona), to demonstrate the same thermal diffusivity and corrosion resistance as conventional coatings, but at a much lower thickness and weight. The company’s patented Emulsion Detonation Synthesis (EDS) process ensures that Innovnano’s 4YSZ has a fine nanostructure with uniform dispersion of mixed oxide components. These resulting powder properties are vital to ensuring that the thermal barrier is highly resistant to micro-cracking and thermal shock, allowing it to expand with the metal underneath without breaking, making it ideal for ‘no-fail’ applications.
“There has been a dramatic growth in the market for high performance materials within the aerospace community and other high performance settings,” says Jo?o Calado, Innovnano’s Technical Director. “Recognising this, Innovnano has recently relocated to a purpose-built manufacturing facility with significantly increased production capacity, and with our advanced EDS technology we are able to provide the highest quality thermal barrier topcoat materials at the volumes that industry needs.”
