The relevance of the work is due to the need in the modern world to obtain products with gradient properties for aerospace and medical applications. The method of laser-assisted cold spraying allows obtaining composite materials by additive technology. As a result of this work, a layer of material was constructed from a mechanical mixture of aluminum Al powder with corundum powder Al2O3, then the structure and properties of the material obtained were studied, and zones of gradient transition were identified.

The article deals with the ongoing development of the universal rotary module URM 02. The high weight of the components from which the modules are assembled proved to be a significant problem. As well as the weight of the connecting parts that are needed to assemble the manipulator or robotic arm. Design changes have resulted in a reduction in weight compared to older generations of modules, but in order for the manipulator to function properly, further weight reduction is required. The article describes the procedure for lightening components by changing the material and the design changes that result from it. The original aluminium alloy was replaced by a continuous carbon fibres composite produced using CFR (Continuous Fiber Reinforcement) additive technology. Here you should describe the paper idea in short.

Two types of aluminium metal matrix composites (Al-MMCs) were prepared by cold spray process. The first Al-MMC was reinforced with granite rock and the second was reinforced with limestone rock particles. Al powder and rock powders (granite or limestone) were mixed to homogeneous mixtures and sprayed onto the Al substrate. The microstructure of as-sprayed composites was compared with microstructure of MMCs reinforced with commercially available Al2O3. The microstructures of Al-MMCs reinforced with granite and limestone were affected by hardness of rocks, particle sizes and compositions of the mixture. The coating is formed through high velocity impact of solid powders. The diameter of Al powder was about 30 μm and diameters of rock powders were from 5 to100 μm. Rock particles are distributed uniformly through the coating, maintaining their irregular morphologies. However, some large sized particles cracked and fragmented. The powder porosity was approximately 2.3 % for both types of Al-MMCs. Porous microstructure leads to lower critical velocity. The results indicate that, introducing irregular morphologies and/or pores into the feedstock. High quality metallic coatings can be more easily deposited by cold spray.

Additive Manufacturing Technology

Cold spray technology is a method of deposited metal coatings by high-speed particle impact, especially in the preparation of metal alloy materials (Cu alloys, Ti alloys, Al alloys, Ni-based alloys, Mg alloys, stainless steels, and high-temperature alloys, etc.) The performance is particularly outstanding. The sprayed materials have better mechanical properties, mechanical properties, and service life, such as tensile strength, fatigue strength, and corrosion resistance. Cold spray technology can prepare corrosion-resistant coatings and high-temperature coatings, Wear-resistant coatings, conductive coatings, and anti-oxidation coatings and other functional coatings. From the perspective of process technology and equipment design, cold spray technology can be applied to the field of additive manufacturing technology, which not only reflects the repair function but also the manufacturing function, and applies cold spray technology and repairs the parts produced by additive manufacturing – Selective Laser Melting technology. The defects and problems are of great significance. This article summarizes the repair process and technical characteristics of cold spray technology, and repairs and protects the Cu, Ti, Al, Ni, Mg, and stainless steel and other metals and their alloys from corrosion, fatigue, and wear. The maintenance is reviewed, and the application of combining cold spray technology with additive manufacturing – Selective Laser Melting technology is proposed. Many materials can be used in the field of cold spray technology and Additive Manufacturing – Selective Laser Melting technology. In the communication between the two, the combination of technology and method is of great significance; the influence of spraying parameters of cold spraying technology (such as powder particle shape, spraying angle, spraying distance, critical speed and temperature of particles and substrate, etc.) on spraying effect and efficiency are proposed. Finally, the development of cold spray technology: post-processing of parts, critical speed and numerical simulation are possible.

Aims:: The main goals of this research are exploration of energy-efficient building materials when replacing natural materials with industrial waste and development of the theory and practice of obtaining light and ultra-light gravel materials based on mineral binders and waste dump ash and slag mixtures of hydraulic removal. Background.: Experimental data on the conditions of formation of gravel materials containing hollow aluminum and silica microsphere with opportunity of receipt of optimum structure and properties depending on humidity with the using of various binders are presented in this article. This article dwells on the scientific study of opportunity physical-mechanical properties of composite materials optimization are considered. Objective.: Composite material contains hollow aluminum and silica microsphere. Method.: The study is based on the application of the method of separation of power and heat engineering functions. The method is based on the use of the factor structure optimality, which takes into account the primary and secondary stress fields of the structural gravel material. This indicates the possibility of obtaining gravel material with the most uniform distribution of nano - and microparticles in the gravel material and the formation of stable matrices with minimization of stress concentrations. Experiments show that the thickness of the cement shell, which performs power functions, is directly related to the size of the raw granules. At the same time, the thickness of the cement crust, regardless of the type of binder, with increasing moisture content has a higher rate of formation for granules of larger diameter. Results.: The conditions for the formation of gravel composite materials containing a hollow aluminosilicate microsphere are studied. The optimal structure and properties of the gravel composite material were obtained. The dependence of the strength function on humidity and the type of binder has been investigated. The optimal size and shape of binary form of gravel material containing a hollow aluminosilicate microsphere with a minimum thickness of a cement shell and a maximum strength function was obtained. Conclusion.: Received structure allows to separate power and heat engineering functions in material and to minimize the content of the excited environment centers.
