“…The problem of improving, improving and producing different types of aluminum alloys is present in different countries [15,16]. Like the application of pure aluminum, the main goal is to achieve the highest hardness, durability, corrosion resistance, plasticity, and other properties when considering the application of aluminum alloys in the automotive industry, which depends on the specific application of aluminum alloys for certain parts and vehicle assemblies.…”

The paper deals with the considerations related to the basic properties and application of primarily aluminum alloys and composite materials for different purposes with the focus on the automotive industry. Through the description of the basic characteristics of aluminum alloys, the starting points for their application in different technical systems are given. On the other hand, the advantages and disadvantages of the use of certain aluminum alloys, along with the guidance and compounds and elements whose use is further enhanced and enriched by aluminum alloys, are predominantly presented. The application of aluminum alloys in the automotive industry, as well as the particular types of aluminum based materials used for individual aggregates and circuits of motor vehicles, as well as their behaviour in different operating modes are imposed as a key chapter of the work. Ultimately, the advantages that are primarily achieved with the vehicle are obtained by the use of aluminum alloys and composites, with the conclusion that there is still space in the field, further improvement of the characteristics of aluminum alloys, and in the field of expansion of the diapason of their application.

Abstract. The car industry uses a tremendous number of materials to build cars, including iron, aluminum, steel, glass, rubber, petroleum products, copper, steel and others. These materials have evolved greatly over the decades, becoming more sophisticated, better built, and safer. They've changed as new automotive manufacturing technologies have emerged over the years, and they're used in increasingly innovative ways. This article is devoted to systematization information on the introduction and application of modern materials in the automotive industry.Given both domestic and foreign sources of information, it follows that car manufacturers are constantly pushing to create the lightest cars possible to increase speed and power. Research and development into lightweight materials is essential for lowering their cost, increasing their ability to be recycled, enabling their integration into vehicles, and maximizing their fuel economy benefits. Light weighting without loss of strength and speed properties is the present, and the future, of the automotive manufacturing industry. It brings innovative materials to the frontline of design.

“…Розглядаючи формування краплини металу електрода можна зазначити, що основний вплив визначається співвідношенням між аксіальною силою, яка виникає внаслідок так званого «пінч-ефекту» та силою поверхневого натягу [4,6]. Зростання температури нагріву рідкого металу супроводжується зниженням коефіцієнта поверхневого натягу [6,9].…”

Purpose. The purpose of work is a comparative analysis of chemical compounds influence on the process of electric arc forming and condition of its burning. Methodology. Material for an electrode was a wire 3 mm in diameter of low carbon steel with contain of carbon 0.15%. As chemical compounds, which determine the terms of forming of arc welding were used kaolin; CaCO3 with the admixtures of gypsum to 60%; SiO2 and Fe – Si with the iron concentration to 50%. Researches were conducted at the use of direct electric current and the arc of reverse polarity. As a source of electric current the welding transformer of type PSO-500 was used. On the special stand an initial gap between the electrode and metal-plate was equal to 1–1.5 mm. The interelectrode interval was filled with the probed chemical compounds and it was formed an electric arc. In the moment of electric arc arise the values of electric current and the arc voltage were determined. After the natural break of electric arc, the final size of the gap between electrodes was accepted as the maximal value of the arc lengths. Findings. In the conditions of experiment the metal transfer in interelectrode interval corresponded to the drop mechanism. According to external characteristics the ratio between the maximal arc length and the power of electric discharge has the appearance of exponential dependence. Specific power of electric arc characterizes environment of interelectrode interval in the moment of arc forming per unit of its length. Originality. 1. On the basis of influence analysis of the studied chemical compounds on the formation processes of electric arc inversely proportional relationship between the power of the electric current and the maximum arc length to the moment of its natural break is defined. 2. The ratio between the maximal arc length and the power of electric current with sufficiently high correlation coefficient is subjected to the exponential dependence. Influence of the studied compounds on the process of electric arc forming is determined using the degree values of the obtained ratio. 3. The value of specific power of electric current in the moment of electric arc forming per unit of its length can be accepted as the parameter, which characterizes the environment in the interelectrode interval. Practical value. In the conditions of identical adjusting strength of electric current it is determined the gradation of the studied chemical compounds in the order of increase of their influence on the process of the arc burning. Kaolin has the minimum influence and Fe – Si – the maximal one.
