“…To solve these problems and further intensify this process by reducing the time to create the juvenile surface of the metal being treated, it seems appropriate to investigate the effect of hightemperature fluxes [5,6]. In addition, the use of fluxes allows the coating process to be carried out without the vacuum equipment use [7].…”

The results of the development of the flux CaO-Li2CO3-B2O3, operating in the oxidizing environment of the furnace, are shown. Flux is used to protect the melt from oxidation and removal of oxides from the coated sample surface. The use of this flux in open furnaces made it possible to apply high-quality nickel coatings with a thickness of 18 μm, which is comparable to the thickness of coatings obtained in vacuum furnaces in argon atmosphere. The negative effect of flux components on the sample surface was noted during prolonged contact under the conditions of the oxidizing environment of the furnace. Practical application of the research results will provide high-quality diffusion coatings on metal products. In addition, economic efficiency is maintained through accessibility of the equipment and flux components.

The article presents the results of the technological weldability studies for K70 strength class steel. A gradation of the studied semi-finished products by their repairability (by the number of the allowed local reheat of the material during the welding and repair processes) is proposed. The viscosity reducing of the metal in the overheating zone, determined by the magnitude of the impact test with Charpy samples at the temperature – 40° C was a basis for the gradation condition. The influence of the welding heat input and the number of reheats on the HAZ metal viscosity is established. Thus, the obtained results allow us to state the low technological weldability of this steel, taking into the account such an important indicator as the repairability of the material.
