Objective

This potential new Annex would focus on the evaluation and performance measurement of advanced engineered coatings. Examples of coatings could be nanostructured coatings, low friction diamond-like-carbon films, and multiphase ceramic matrix composite coatings. These coating materials hold considerable promise for improving durability and wear resistance, reducing parasitic frictional losses, and reducing corrosion and oxidation for in cylinder components for high efficiency engines. However, for these advanced materials, coating substrate adhesion, durability assessment, local and global mechanical properties measurement techniques are currently lacking, impeding the rapid development of energy efficient technologies world-wide.

Objective

This potential new Annex would focus on the R&D of nanomaterials and nanostructured materials. This class of materials hold tremendous promise for unprecedented properties and performance level in terms of friction reduction, selective catalytic actions, smart materials that can change stiffness and hardness as a function of stress state and/or thermal conditions. Many of these materials are being developed for aerospace applications and many of them have potential impact in transportation technologies.

Objective

Corrosion of magnesium alloys is of prime concern in transportation applications since road salt in cold climates accelerates corrosion when such alloys are in contact with dissimilar metals (i.e., galvanic corrosion). This potential new Annex would focus on the corrosion protection R&D of magnesium alloys.
