Název v původním jazyce

Present and possible future applications of superhard nanocomposite coatings

Popis výsledku v původním jazyce

Recent investigations into the multicomponent (TiAlSi)N and TiBN superhard coatings revealed that the nonostructure, properties and deposition conditions needed for their preparation are in agreement with the known generic concept for the design of novelsuperhard nanocomposites due to thermodynamically driven phase segregation. All coatings to be reported here were developed on a production scale plasma PVD&CVD equipment. Depending on the composition and deposition conditions the hardness of the coatings is controlled in the range between 35 and 45 Gpa or higher. More important is the appropriate combination of high hardness with other properties, such as fracture toughness, oxidation resistance, adhesion, etc The efect of these properties on the resulting utility value of the coated tools will be discussed with respect to the abailable cutting tools made of cemented carbide and coated with the nanocomposites.
