ABSTRACT
This paper presents the results of research on the influence of the technological parameters of the brazing process on the structure formation of the titanium alloy TA15 brazed joints. The effects of surface preparation and brazing modes on the spread area of the Ti-Zr-Me filler metal on TA15 titanium alloy were analyzed. Findings indicate that the spread area for samples subjected to mechanical cleaning is 10-20% larger than for samples treated by standard acid etching (HNO3+HF). Additionally, increasing the heating temperature from 900 °C to 950 °C enlarges the spread area by 10%. The study also explored the structuring of brazed joints, revealing that extending the exposure time during brazing increases joint width, homogenizes the structure, and boosts shear strength by 15%.
