Ceramic-Metal Bonding – Metalization of Ceramics and Vacuum Seals by Morgon Technical Ceramics

Dissimilar Metals JoiningThe joining of ceramics to metals creates its own engineering challenges that require specialist expertise.

Morgan Technical Ceramics are favored in a wide range of electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures, they have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistivity. They are also hard, and have excellent dimensional stability.

Affordable Lightweight Ceramic/Aluminum Brake Rotors Developed

The latest Tesla Model S is supposed to be an upgrade from the 2010 iteration pictured here, though some questions persist.

When it comes to making cars more energy-efficient getting their weight down is one of the best things you can do. Unfortunately, the cast iron brake rotors currently used in most vehicles are quite heavy. Soon, ceramic-coated aluminum rotors may be a cost-effective lightweight alternative for economy cars.

Aluminum expands three to four times more than ceramics. Ceramic coating can’t be applied to the aluminum rotors in one continuous piece. If it was, it would crack as the aluminum beneath it expanded. The solution comes down to soldering the ceramic onto the aluminum in the form of individual tiles laid side-by-side.
