AI Technical Summary
Existing metal-based ceramic composite membrane preparation processes are cumbersome and costly, and the bonding strength between the metal substrate and the ceramic membrane layer is low, making it prone to cracking and difficult to achieve industrial production.
The process involves mixing and pressing alloy powder with ceramic powder, combining pressure forming and sieving technology to evenly distribute ceramic powder on the surface of a metal substrate, and then preparing a metal-based ceramic composite film through heat treatment. This reduces the difference in thermal expansion coefficients and improves the bonding strength.
The preparation process was simplified, the cost was reduced, and the bonding strength between the film layer and the substrate was improved, resulting in a complete and uniform metal-based ceramic composite film suitable for industrial production.
