Engineered Surfaces – Where Nano Materials Meet Industrial Applications


Yang-Tse Cheng, General Moters

Most mechanical devices and manufacturing tools cannot function without a properly engineered surface. The properties of surfaces are largely determined by their composition and structure at the nano and micrometer length scales. In this presentation, I shall provide an overview of our recent work on synthesis and characterization of nanostructured materials as engineered surfaces for several automotive applications. Examples include (1) nanocomposite coatings and nanowires, (2) microscopic shape memory and superelastic effects and their tribological applications, (3) superhydrophobic surfaces, (4) modeling of instrumented indentation in viscoelastic solids, and (5) coatings for dry machining of aluminum alloys and for automotive components. These examples help illustrate research opportunities in surface engineering, nano-structured materials, and their novel industrial applications.
