Thermal Barrier and Protective Coatings: Used in high-temperature components such as aero-engine blades, the deposited Cobalt Aluminate films effectively isolate heat and resist oxidation and thermal corrosion.
Optical and Decorative Thin Films: Due to their stable blue hue and durability, they are commonly used to prepare high-end optical filters, weather-resistant decorative coatings, and art glass coatings.
Semiconductors and Functional Thin Films: In the microelectronics field, it can serve as a special dielectric layer, passivation layer, or a material source for preparing novel magnetic and catalytic functional thin films.
Q1: How is the temperature resistance of cobalt aluminum spinel targets?
A1: Excellent. Its spinel structure is extremely stable at high temperatures, making it suitable for thin film preparation requiring long-term exposure to high-temperature environments.
Q2: What color is the film deposited using this target?
A2: It typically exhibits a stable, vibrant blue color. The specific hue can be fine-tuned by adjusting the sputtering process parameters.
Q3: What is the difference between it and alumina targets?
A3: The main difference lies in composition and properties. Cobalt Aluminate incorporates cobalt, which, while maintaining high stability, imparts a unique blue color and potential functional properties to the material.
Q4: Is custom-made for non-standard sizes supported?
A4: Yes. We can customize targets of different shapes, sizes, and thicknesses according to your coating equipment cavity and process requirements.
