The integration of ceramics with metals or polymers—commonly referred to as ceramic-to-metal or ceramic-to-polymer joining—has long been a focus of material engineering research. Due to ceramics’ inherent hardness and exceptional resistance to high temperatures, developing reliable joining techniques is essential for producing durable, multifunctional components that perform under demanding conditions.
Common methods for joining ceramics to other materials include:
1. Mechanical Fastening (Screwing): Used in assemblies exposed to strong mechanical impact, such as machine mechanisms, where detachable joints are required.
2. Shrink Fitting: Utilizes the ceramic’s low thermal expansion and high compressive strength to create tight, pressure-resistant joints, often applied in reinforced ceramic piping systems.
3. Resin Molding: Involves embedding ceramic parts within molded resin structures, allowing simple, integrated designs and shape flexibility.
4. Brazing: A conventional yet highly effective method for ceramic-to-metal sealing. A molybdenum–manganese coating is first fired onto the ceramic surface to form a metallized layer, which is then joined to the metal component through high-temperature brazing.
5. Adhesive Bonding: Employs specialized high-temperature adhesives formulated to provide strong adhesion between ceramics and dissimilar materials such as metals or polymers.
The ability to join ceramics with other materials has opened a wide range of industrial applications. In aerospace, it enables the production of components capable of withstanding extreme environments. In electronics, it supports the creation of advanced circuitry and hermetic packages. In biomedical fields, it contributes to durable and biocompatible implant designs.
Continuous advancements in materials science and engineering are further improving these joining methods, resulting in stronger interfaces and expanding the role of ceramic-based materials in modern industry.
