The methods of creating the advanced nanomaterials and nanotechnolo-gies of functional multicomponent coatings Avinit (mono- and multilayer, nano-structured, gradient) to improve the performance of materials, components and parts of aerotechnical purposes are considered. The vacuum-plasma nanotechnologies Avinit were developed based on the use of gas-phase and plasma-chemical processes of atomic-ionic surface modifi-cation and the formation of nanolayer coatings in the environment of nonsteady low-temperature plasma. Considerable attention is paid to the equipment for application of functio-nal multilayer composite coatings: an experimental-technological vacuum-plas-ma automated cluster Avinit, which allows to implement complex methods of coating (plasma-chemical CVD, vacuum-plasma PVD (vacuum-arched, magne-tron), processes of ionic saturation and ionic surface treatment, combined in one technological cycle. The information about the structure and service characteristics of Avinit coatings has a large place. The results of metallographic, metallophysical, tribological investigations of properties of the created coatings and linking of their characteristics with pa-rameters of sedimentation process are described. The possibilities of parameters processes regulation for the purpose of reception of functional materials with the set of physicochemical, mechanical complex and other properties are considered. The issues of development of experimental-industrial technologies Avinit and industrial implementation of the developed technological processes to increase of operational characteristics of aerotechnical products are addressed in detail. Attention is paid to the development prospects of vacuum-plasma nano-technologies Avinit and expansion of these methods applications in mechanical engineering, aviation, power-plant industry, space industry and other fields of science and technology. The book is aimed at specialists working in the field of ion-plasma surface modification of materials and functional coatings application.
