Introduction to coating of multilayer zirconia disk？

The coating of multi-layer zirconia disks can be introduced from the following aspects:

First, coating materials

The main component of the coating of the multi-layer zirconia disk is zirconia (ZrO2), which is a material with high hardness, high wear resistance, high corrosion resistance and excellent thermal stability. Zirconia coatings are prepared by special processes (such as ion beam spraying, arc ion plating, etc.), which can form a hard and dense protective layer on the surface of the substrate.

Second, coating structure

The coating of multi-layer zirconia disk usually adopts multi-layer structure design to improve the comprehensive performance of the coating. This multilayer structure may consist of layers of coatings with different compositions and properties stacked together to form a composite coating with gradient changes. For example, some multilayer zirconia coatings may include a dense zirconia layer for increased wear resistance, a transition layer for increased binding force, and a surface protection layer for increased corrosion resistance.

Third, coating performance

1. High hardness and wear resistance: zirconia coating has extremely high hardness, which can effectively resist external wear and prolong the service life of the substrate.

2. Excellent corrosion resistance: zirconia coating has good stability for a variety of chemical media, and can maintain the integrity and performance of the coating in harsh environments.

3. Good thermal stability: zirconia coating can still maintain stable performance at high temperatures, and it is not easy to occur thermal deformation or thermal cracking.

4. Excellent binding force: By optimizing the interface between the coating and the substrate, the multi-layer zirconia coating can achieve a solid bond with the substrate and is not easy to fall off.

Fourth, application field

The coating of multi-layer zirconia disk is widely used in mechanical equipment, chemical equipment, automotive industry, aerospace and other fields. For example, in the field of mechanical equipment, zirconia coatings can be used to manufacture heavy duty machinery, ceramic molds and other parts; In the field of chemical equipment, it can be used to manufacture corrosion resistant reactors, storage tanks and other equipment; In the automotive industry, it can be used to manufacture key components such as turbochargers and piston rings; In the aerospace field, it can be used to manufacture high-temperature parts such as engine blades, combustion chambers, etc.

Fifth, preparation process

The preparation process of multilayer zirconia coating is complex and varied, and the common preparation methods include ion beam spraying, arc ion plating, plasma spraying, etc. Each of these processes has advantages and disadvantages, and the appropriate preparation method needs to be selected according to the specific application requirements and substrate characteristics.

Sixth, precautions

When using multi-layer zirconia disks, it is necessary to pay attention to the protection and maintenance of the coating. Avoid excessive impact or scratches on the coating, so as not to affect the performance and service life of the coating. At the same time, it is necessary to regularly check the integrity of the coating during use, and timely discover and deal with coating defects.

In summary, the coating of multi-layer zirconia disk has excellent performance and wide application prospect. With the continuous development of science and technology, the preparation process and application field of multi-layer zirconia coating will continue to expand and improve.
