The article deals with the mechanism of laser alloying of P6M5 steel and the character of its change. The results of studies of laser doping and a change in the results with varying parameters of laser radiation are proposed. Tungsten boride (W2B5) was used as a legrant. The authors spent an analytical assessment of the mixing mechanism in laser doping. It is noted that the research of this sphere do not have a systemic nature. Many authors who explore this problem, think that it is one of the main and most controversial in laser doping. Therefore, the results are got by different scientists cannot be systematized due to significant differences in the schemes and conditions of research. It is investigated the processes occurring during the formation of the structure of surface layers during laser doping. It is obtained optimum laser processing conditions. It is proved experimentally that the processing speed during laser alloying effects on the nature of the distribution of the legrant in the alloy bath and regulates the mixing mechanism, including both diffusion and convection.

2020

Innovative technologies in the construction industry have taken a firm position in the construction-engineering sector. The article discusses the new technologies used for strengthening the foundations of different types. A study on the traditional method of strengthening foundations has been carried out and indicators of new technologies use are presented. Traditional options for strengthening foundations by increasing the foundation base are considered, from the point of view of geotechnics and manufacturability in relation to loose and saturated soils. The operational characteristics of new technologies during the work on strengthening the foundations are given.

“…To identify the structure of the alloy, etching is used. Etching is the effect of acids, alkalis and salts on the surface of the test sample [3]. The essence of the process of detecting the structure of metal and alloy using etching is the different degree of dissolution and staining of individual structural components: -grains [4]; -solid solution; -chemical compounds [5].…”

Microanalysis provides the ability to determine the structure of metals with the naked eye and using a microscope. Microanalysis allows you to determine the types of shapes and sizes of grains, inclusions of foreign phases, the presence of micro-voids and their location. Before conducting the study, the sample slots made from the part are prepared. The quality of the manufactured strip affects the accuracy of determining the structural structure. Their surface is polished to a mirror Shine and etched with special reagents.
