Push-button for geometric measurement of component made up of light metal i.e. aluminum, and light metal alloy in coordinate measuring equipment, has test specimen coated using coating material that is selected from one group

摘要

The push-button has a test specimen (3) coated using coating material. The coating material is selected from a group consisting of titanium nitride, titanium aluminum nitride, titanium carbide, titanium carbonitride, titanium diboride, titanium aluminum silicon nitride, aluminum chromium nitride, aluminum oxide, chromium carbide and chromium oxide. The coating is performed using multiple coating layers, where the layers include zirconium oxide in addition to the coating material. Chromium oxide is additionally used as the coating material.
