Comparative Analysis of Electrochemical and Laser Marking for Gyroscopic Application

Abstract

Technological aspects of the contrast image formation on the metal surfaces covered with titanium nitride coating are considered. Comparative analysis of electrochemical and laser marking technologies used for creation of contrast images that provide functionality of optoelectronic readout systems is presented. It was revealed that laser marked images on titanium nitride surfaces are more homogenious than electrochemical one. The signal obtained from the optical sensors scanning the surface with laser marked images is more stable.
