Conductive nanocomposite ceramics as tribological and electrical contact materials

Fundamental Tribological Properties of Ceramics

Electrical Resistivity and Contact Resistance of Electrically Conductive Silicones

Cable accessories for mediumand high voltage applications contain field grading and field zoning parts or layers. These parts often consist of electrically conductive silicone elastomers. The electrical conductivity is achieved by using selected and long-term tested carbon blacks. Conductive layers and parts are used to provide safety against exposure, inner shielding and an electrical contact ...

Temperature Dependence on Structural, Tribological, and Electrical Properties of Sputtered Conductive Carbon Thin Films

Conductive carbon films were prepared at room temperature by unbalanced magnetron sputtering (UBMS) on silicon substrates using argon (Ar) gas, and the effects of post-annealing temperature on the structural, tribological, and electrical properties of carbon films were investigated. Films were annealed at temperatures ranging from 400 °C to 700 °C in increments of 100 °C using a rapid thermal a...

TiC-based nanocomposite coatings as electrical contacts

This Thesis concerns the advanced surface engineering of novel TiC-based nanocomposite and AgI electrical contact materials. The objective is to make industrially applicable coatings that are electrically conductive and wear-resistant, and have a low coefficient of friction. I have studied electrical contact systems consisting of a Cu substrate with a Ni diffusion barrier and loading support, a...

Chemomechanics of ionically conductive ceramics for electrical energy conversion and storage

Functional materials for energy conversion and storage exhibit strong coupling between electrochemistry and mechanics. For example, ceramics developed as electrodes for both solid oxide fuel cells and batteries exhibit cyclic volumetric expansion upon reversible ion transport. Such chemomechanical coupling is typically far from thermodynamic equilibrium, and thus is challenging to quantify expe...
