Resumo
The paper reviews the present-day trends in the development of new types of wear-resistant coatings, including nanostructured ones, for PCBN tools. The main currently pursued approaches to creation of high-hardness nanostructured coatings are discussed. Based on the analysis of wear behavior of PCBN tools, some new approaches to the development of promising wear-resistant coating systems have been identified, namely: (i) selecting the structural components of a coating, which should act as a hard grease to effectively reduce the tool wear rate; (ii) adding the compounds that inhibit any chemical reactions in the cutting zone; (iii) reducing the friction coefficient and contact loads through the use of solid lubricants and running-in layers of a coating; (iv) providing a coating with the required structural state.
