8% yttria-stabilized zirconia (ZrO₂-8% Y₂O₃) Powder Application

Coating Properties

• Hardness: Typically, the coating hardness can reach approximately 600 HV0.3. This hardness endows the coating with good wear resistance, enabling it to withstand a certain degree of friction and abrasion.

• Temperature Adaptability: It is suitable for use at temperatures below 1250℃. Within this temperature range, the coating maintains stable performance without significant deformation, melting, or performance degradation.

• Porosity: The porosity generally ranges from 6% to 20%. Appropriate porosity gives the coating a low thermal conductivity, providing it with good thermal insulation performance. Meanwhile, it also helps enhance the coating's thermal shock resistance.

• Other Properties: This coating material exhibits excellent fluidity, which is beneficial for coating preparation via processes such as plasma spraying. Its ultra-low monoclinic phase content ensures the coating has excellent thermal shock resistance, hot corrosion resistance, and resistance to high-temperature gas erosion.

Typical Applications

• Aerospace Field: It can be used on components such as the combustion section parts, transition sections, jet engine combustion chambers, and intake valves of aero-engines. Serving as a thermal barrier coating, it effectively protects the metal substrate, reduces its operating temperature, and improves the engine's efficiency and reliability. For instance, applying this coating to gas turbine blades can enhance the blades' high-temperature resistance and thermal shock resistance, extending their service life.

• Power Generation Field: It is suitable for parts like the blades, combustion liners, and turbochargers of gas turbines in power generation. It helps improve the thermal efficiency of gas turbines and reduce energy consumption. Additionally, it can be applied to components of some high-temperature boilers to achieve thermal insulation and protection.

• Other Fields: It can also be used on parts that need to withstand high temperatures and thermal shocks, such as rocket nozzles and cylinder heads, to improve their performance and service life. Moreover, this coating can be adopted on high-temperature components of some industrial furnaces to enhance thermal insulation effects and the high-temperature resistance of the components.
