The main objective of this paper is to offer ion-plasma technology for production of Ti (titanium) and titanium nitride (TiN) erosion-resistant nanocoatings for the machine building products, which ensures the coatings with optimum and stable properties. As a result of experiments and processing experimental data the optimum composition of ion-plasma titanium and titanium nitride nanocoatings was obtained and offered.The approbation of the developed technology on the existing machine building products (compressor blade of the helicopter gas turbine; base material: Incoloy 800) was carried out. The comparative study on the influence of the coating on the surface quality, coefficient of friction, adhesion strength and erosion resistance was done. For evaluation of the obtained nanocoating surface’s quality 2D and 3D surface description approaches were applied. Achieved results prove the effectiveness of offered ion-plasma technology for production of titanium and titanium nitride erosion-resistant nanocoatings with appropriate and stable properties.

The presented article analyzes regional markets, for heavy industry and machine building products for the Azerbaijani economy. In terms of trade relations and territory, the markets of Turkey, the Russian Federation, Georgia, the Islamic Republic of Iran, Moldova, Belarus, Ukraine, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan and Armenia were selected and evaluated. The database of the study consists of mutual import and export data for the mentioned countries in 2014–2018. Based on the import-export data collected covering the years 2014–2018 on six-digit codes of regional markets, the revealed comparative advantage and localization coefficients on import and export were calculated. As a result, importing and exporting countries have been identified in the regional markets through the calculated coefficients for each of the 5 years of heavy industry and machine building products considered. Thus, in terms of imports and exports, the countries with the highest coefficients were selected.

Technological parameters for electroplating cadmium alloy (Cd (24)-In and Cd (33)-Sn) coatings from low toxic solutions have been proposed. Since the fabricated alloy coatings possess low internal stress and microhardness, good adhesion property, high corrosion and wear resistance, they can be used as protective coatings for machine building products to enhance reliability and operability thereof. The presence of good solderability and low values of transient electric resistance in climatic testing favor these coatings to be applied in hetero-structured contact systems of instrument making products for increasing their reliability and operability in a tropical marine climate.

The paper studies and analyzes the use of additive technologies in modern foundry production, determining their innovative development to create new products with high quality, reliability and determining its competitiveness in the world market of machine-building products. The essence of SLS-technology is defined as follows: model material - polystyrene powder with particle size of 50-150 microns - is rolled by a special roller on the working platform installed in a sealed chamber with an inert gas atmosphere - nitrogen. The laser beam "runs" where the computer "sees" the "body" in the given section of the CAD-model, as if "shading" the section of the part, as it is done by the constructor with a pencil on the drawing. In this case the laser beam is a source of heat, under the influence of which sintering of polystyrene particles takes place (working temperature - about 120°С). SLA, Polyjet and DLP technologies are the most widespread for metal casting. The first method involves sequential "running" of the laser beam over the entire surface of the layer to be formed where the model "body" is in the cross section. The second method of curing is performed by a beam in the form of a line in the process of layer formation due to radiation from a controlled ultraviolet lamp. The third way implies illumination of the whole layer simultaneously by creating the so-called mask - a "photo" of the current CAD-model section. Thus, additive technologies in modern foundry production have radically reduced labor intensity and costs of creating new products, which have high quality and reliability indicators and determine their competitiveness in the global market of machine-building products.

Comparative studies of the effect of discrete surface hardening by standard ion-plasma technology and discrete oxidation technology on wear resistance have been carried out. Metallographic studies have shown that discrete oxidation has a polycrystalline structure. It was found that the technology of discrete oxidation makes it possible to increase the hardness by 31% in relation to the uncoated material, and the wear resistance of the cutting tool with oxidation is 1.5-3 times higher than that of the tool hardened by the standard ion-plasma technology.

The actual task in the field of computer-aided design of machine-building objects is to increase the level of automation of structural-parametric analysis of design solutions due to the repetition of their use, reducing the number of design operations and ensuring the corresponding competencies of designers. Developed methods and algorithms should ensure the acquisition of the necessary competencies for the designer for successful project activities in the field of computer-aided design, increasing the effectiveness of training. The system of analysis of design solutions should improve the quality of design solutions implemented in CAD KOMPAS-3D. In this paper, an overview of methods, systems and tools for analyzing design solutions implemented in the CAD-3D environment. The main features of such systems are described, their main disadvantages are identified: the lack of functions for determining non-optimal sequences of design operations, the inability to automatically rebuild a three-dimensional model of a machine-building product on the basis of analysis of the design model tree. A complex system for the analysis of project solutions and the training of a designer was developed and implemented, based on methods, models and algorithms for analysis and adaptive learning. The results of a computational experiment are presented, on the basis of which it can be concluded that the use of developed software enhances the efficiency and quality of the designer's training in the processes of constructing three-dimensional solid-state machine-building products in CAD KOMPAS-3D.
