Increasing interest receive materials with a high ratio of hardness to Young's modulus as mechanically adaptable coatings on machine parts, where their high compliance combined with high hardness reduce the wear. After a brief overview of the the recent search for new super- and ultrahard materialds I shall concentrate on the progress achieved in the understanding of the properties, preparation and industrial applications of hard and superhard nano-structured coatings on tools for machining (drilling, milling, turning), forming, stamping, injection moulding and the like. popup.nrat_date 2025-05-12 Close
