Abstract
The possibility of developing and blackening the surface of titanium alloy by nanosecond pulses of an ArF laser, a Nd:YAG laser, and a copper vapor laser for use in space engineering is studied in this work. For various irradiation regimes, the optimal parameters for the formation of the necessary surface structures were determined. The possibility of applying a reliable color layer without the use of any paints on the surface of a titanium alloy as a result of treatment with an Nd:YAG laser beam is shown. In particular, this method of laser processing will make it possible to obtain black color on the surface of devices used in outer space to absorb and dissipate solar energy, and it is expected to increase the radiation resistance of such coatings and their service life.
