Abstract

A method has been developed for preparing the surface of titanium alloys, which provides an increase in the strength characteristics of titanium–composite adhesive joints. When preparing the surface of parts made of titanium alloys, it is not enough to use only mechanical treatment, and when combined with chemical surface treatment, the formation of strong bonds is possible. Surface preparation is carried out by forming a relief structure by applying corrugations on the machine, followed by removal of the oxide film and the formation of a high degree of microroughness by etching in a mixture of acids. Preparing the surface of titanium surfaces with a new method allows minimizing the influence of the human factor, improving the adhesion characteristics of the surfaces of parts, and increasing the time interval between mechanical preparation and gluing. Studies have been carried out to determine the ultimate strength in shear, bending, torsion, compression, tension, as well as to determine the effect of the gap in time intervals between mechanical surface preparation and gluing on the strength characteristics of the adhesive joint on titanium–composite samples with different titanium surface preparation. The analysis of the influence of methods of surface treatment of parts made of titanium alloys on the strength of the adhesive joint is carried out, taking into account the influence of thermal exposure in vacuum conditions, simulating the operation of a spacecraft in space conditions.
