FIELD: measurement equipment.
SUBSTANCE: after final balancing and sphere development, a wear-resistant thin-film coating of titanium nitride is applied to spherical surface of gyroscope rotor using a magnetron sputtering method, and then, a raster pattern is formed on the above coating by means of laser marking. With that, laser processing methods are chosen from the condition of obtaining the raster pattern with a thickness that is smaller than thickness of the coating, which provides return nature of a process since it allows removing the wear-resistant coating for example using an etch removal method and again applying it and forming a raster pattern at any deviations in parameters of a fabricated rotor.
EFFECT: improvement of the method.
