zirconia-based thermal spray powders Applications
zirconia-based thermal spray powders is a kind of Yttrium stabilized zirconia powder. There are several unique properties of it, such as high melting point, excellent thermal insulation, good chemical stability, and low thermal conductivity. Thus, Zirconia thermal spray powder is especially suitable for plama spray applications as below:
1. Aerospace
Thermal barrier coatings(TBC). In jet engines, zirconia-based thermal spray powders is suitable for turbine blades, vanes, and combustor liners. These coatings act as thermal barriers, reducing the heat transfer from the hot combustion gases to the underlying metal components. This allows the engine to operate at higher temperatures, improving fuel efficiency and increasing the thrust – to – weight ratio.
Aerospace structural components. YSZ spray powder works well for coat structural parts of aircraft, such as wing leading edges and nose cones. The coating enhances the component’s resistance to high – speed airflow erosion, high – temperature oxidation, and thermal cycling, thus improving the durability and reliability of the aerospace structure.
2. Energy
Power generation turbines. Plasma sprayed zirconia coatings are suitable for turbine components in gas and steam turbines in power generation. They protect the metal parts from high – temperature corrosion and wear, extend the service life of the turbines, and reduce maintenance costs.
3. Automotive
Engine components. Zirconia thermal spray powder can work as coating material in pistons, cylinder liners, and valves in automotive engines. These coatings reduce friction between moving parts, improve wear resistance, and enhance thermal management within the engine. As a result, the engine’s performance is improved, fuel consumption is reduced, and emissions are lowered.
4. Kiln furniture and machinery
sputtering targets, conveying rollers, kiln furniture, fuel cell production or diverse industrial machinery parts
5. Electronics
Semiconductor manufacturing equipment. YSZ powder is a superior protective coating on components in semiconductor manufacturing equipment, such as chambers and wafer holders. These coatings provide chemical resistance, high – temperature stability, and low particle generation. They are crucial for maintaining a clean and stable manufacturing environment.
