Hard, Superhard and Ultrahard Materials: An Overview,s, carbon nitrides, cubic boron nitride (c-BN) and diamond. These materials are widely adopted in many industrial applications where high hardness, high incompressibility and sometimes chemical inertness and thermal stability are primary requirements. Applications range from abrasives (e.g. polishin吸气 发表于 2025-3-25 15:40:40
Applications for Superhard and Ultra-Hard Materials,s various formats, is the only ultra-hard material currently used for industrial applications. The largest current application area for synthetic diamond is still in the abrasives markets which are expanding as new, ‘difficult-to-machine’ materials (such as CFC and MMC materials) become more widely魔鬼在游行 发表于 2025-3-25 18:39:06

Superhard and Ultrahard Nanostructured Materials and Coatings,erhard because, upon finite shear, electronic instabilities and transformations to softer phases occur, particularly in materials which contain metals with d-electrons or non-binding electron pairs. Hardness enhancement can be achieved in nanostructured materials, but it is limited by grain-boundaryPATHY 发表于 2025-3-26 10:36:26
Future of Superhard Material Design, Processing and Manufacturing, outside the box and using unconventional technologies. The biggest challenges with superhard materials is their inherently lower fracture toughness, expensive to manufacture and difficult to process into final formats or geometries (such as for cutting tools) required by end users. These geometriesCongeal 发表于 2025-3-26 13:38:51
