Ceramic in combination

Ceramic – Metal combination

Ceramics can be combined with various metals using any of a vast array of joining techniques.

The different material characteristics of the materials and their different responses, subject to prevailing ambient conditions, all need to be taken into account. (e.g. higher temperatures elicit different levels of elongation; chemical resistance, mechanical load-bearing properties …)

One further criterion in this connection is the propensity of the components to detach themselves from one another. The choice is limited in many cases by geometric restrictions based on the manufacturing method employed for the metal body.

Ceramic – Plastic combination

Plastic and ceramic injection moldings supplement one another superbly. Both materials can deliver material-specific benefits to the location defined for their use.

This means that both materials ideally complement one another within the context of the total system. The shaping options (geometric latitude) afforded by the injection molding process offer versatile options for both joining partners, in the creation of a functionally compliant and materially compatible connection. These are further enhanced by cost benefits resulting from their relative ease of assembly.

Possible connection techniques for a ceramic-plastic composite:

• Cementing (adhesive)
• Mechanical connection (screwing, plugging in, pressing in, clamping, snap-on connection, crimping
• Spray-coating (sintered ceramic component as an insert in a plastic injection molding)

Ceramic – Ceramic combination

In many cases, ceramic-ceramic composites are chosen for the superlative tribological properties of this combination.

Both material partners exhibit identical material specifications and therefore respond in an identical manner to a very diverse range of application conditions. This does not impair functionality which remains assured even under the least favorable of conditions.

Moreover, these composites exhibit absolutely minimal indications of wear as a consequence of the great surface quality of these materials. The consequence: long service life and reduced lifecycle costs.
