Innovnano, an expert manufacturer of high performance ceramic powders, has developed nanostructured 3 mol % yttria-stabilised zirconia (3YSZ) as an optimised ceramic material for high strength anti-wear applications.
With small grain sizes and exceptional homogeneity, Innovnano’s 3YSZ powder has excellent mechanical and physical properties, including improved phase stability, which helps to extend the lifetime of ceramic linings, coatings and components. Enhancing the durability and tribological performance of components, including cutting tools and nozzles, increases the efficiency of industrial facilities such as steel plants and foundries. With less frequent replacement of parts and reduced equipment downtime, running costs are also minimised.
Using its patented Emulsion Detonation Synthesis (EDS) technology in an automated manufacturing process, Innovnano’s 3YSZ is produced as a highly pure, uniform nanostructured powder with an even distribution of yttria. This homogeneous composition enables the powder to be sintered at lower temperatures, typically 50-75⁰C lower than conventional powders, advantageously keeping the grain size to a minimum (<250 nm). As a result, ceramic coatings and components benefit from both excellent hardness (HV10 >1250) and flexural strength (1100-1800 MPa) for improved performance.
The exceptional chemical and physical homogeneity that Innovnano’s unique EDS manufacturing technology provides also ensures that its 3YSZ is chemically inert, and highly resistant to corrosion and aging. Importantly, the even distribution of yttria guarantees that Innovnano’s 3YSZ exists in a more stable tetragonal phase. This reduces the presence of ‘weak spots’ that are introduced by zirconia phase transformation, which can otherwise lead to micro-cracking and compromised component performance.
João Colado, Head of Special Projects at Innovnano, explains: “Modern manufacturing industries demand materials of the highest quality in order to produce components that are ever more resistant to abrasion and wear-and-tear. With its intrinsic nanostructure, our 3YSZ offers ceramic material with high resistance to corrosion and abrasion to improve the lifespan of components in the manufacturing workflow. As such, Innovnano’s 3YSZ can be used as a reliable alternative to traditional steel components.”
