New research explores a zirconia-based shape memory ceramic that exhibits a unique type of electrically triggered martensitic transformation.

Heat shields help protect vehicle-critical components that could delaminate and fail if exposed to high temperatures for any length of time. This article describes a solution that features ceramic platelets applied via plasma spray onto a metal substrate to create a heat shield that adds additional temperature resistance in comparison to standard pressed aluminum versions.

Zircotec Ltd., UK, originally developed its technologies for use in nuclear reactors. During the last decade, its coatings have been used in several other applications, including orthopedic implants, and the company has expanded into the defense sector with a greater emphasis on heat protection. This Technical Spotlight outlines some of the company's process capabilities.

This article explains how coating technology originally developed for use in nuclear power generating equipment is helping automotive engineers solve heat, wear, and performance challenges using new materials and design approaches.
