Summary
This module will provide guidance and tools for the understanding of hard & superhard material, and tools for design and deposition of nanostructured coatings with a desired combination of functional properties. To reach this goal we will learn about:
- The origin of hardness and the difference between “intrinsic” and “extrinsic” hardness.
- Structure and properties of intrinsically superhard materials and coatings.
- Design and deposition of extrinsically superhard nanostructure coatings with selected functional properties.
- Selected applications in machining, automotive and aerospace sectors.
Topics
- The Nature of Hardness:
- Leading theories of hardness
- How material’s properties determine its intrinsic hardness
- How nano-engineering is used to design coatings with superhigh extrinsic hardness
- Intrinsically Hard and Superhard Materials: Diamond; cubic boron nitride, diamond-like carbon coatings, graphene, and carbon nanotubes
- Extrinsically hard and superhard materials and coatings:
- Hard and Superhard nano-layered and nano-composite coatings
- Selected applications in machining, automotive and aerospace sectors
