INVENTING OF NEW MATERIALS The advancement of new specialized gear will advance the concocting of new materials: To set of nano groups (now and then named ultra scatter materials) concern smaller person (under 100 nanometers) the particles comprising of tens, hundreds or thousand iotas. Properties of nano groups cardinally contrast from properties of perceptibly volumes of materials of the same structure. From nano groups as from vast building squares, it is conceivable to plan deliberately materials with preset properties and to utilize them in synergist responses. Quantum character nano forms makes them to a great degree high innovation and animates advancement of such connected bearings, as: nuclear atomic outline, advances in light of numerical displaying, metrology and the models in light of unique segments of science, registering science and material science, and so forth.

FEATURES OF REALIZATION NANO PROCESSES Nano-mechanical responses can happen in vacuum, gas or in a fluid. The kind of responses is not generally associated with sort of environment in the chamber and can rely on upon different conditions (an electric field, weight, temperature, designation of vitality, properties of substances). Such properties (the snapshot of dipole, nearness of polluting influence, slender impact, and so on.) decide character of continuing responses. Extra impacts (for instance, a reasonable laser light with system controlled length of a wave) can significantly change a course and even a heading of substance responses. These open doors (controlled procedure) in a mix to the recorded above variations of determination of materials and states of doing of nano procedures - make nano-innovation autonomous and even by refined zone of a science and the business of XXI century. A fundamental piece of this circle of learning is scientific demonstrating the nano forms, associated with such new headings, as processing science, figuring material science and registering science.

TECHNICAL APPROACH AND METHODOLOGY Within the structure of the fundamental bearings of examines in foundation takes a shot at gathering nanodispersed artistic composite powders by a technique for a devastating (pounding) in vertical and plane gadgets are done. Along these lines at the very least 50 % of a yield makes particles in the sizes under 300 nanometers. Sol-gel innovation gets mono-scatter nanopowders different structure, incorporating materials from them with the structure of a photon precious stone indicating specific properties in optical territory of a range. Laws of arrangement of structure and properties nanocrystalline materials in conditions static both element stacking and sintering are examined in the field of the temperatures which are not bringing about escalated re-crystallization. Strategies for affidavit of coatings in vacuum get multilayered nanosized (thickness of one layer  10 nm) metal, earthenware metal and composite coatings on the titan and substrates from different materials. In establishment improvement of carbon materials (on a premise nanosized precious stones – ultra scattered jewels UDD) and uncommon oxides pottery, including corundum, coordinated on gathering of materials with thickness near hypothetical, with uniform structure, high sturdiness, hardness, wear resistance, an abnormal state of physical properties, heat conductivities and thermo security are led. Absence of conventional innovation of gathering of such materials is the high temperature of their cooking (1700 – 1750 О С ), that basically confines volumes of their assembling and application.
