Adhesion and corrosion behavior of Al-Zn and TiN/Ti/TiN coatings on a Du-0.75 wt% ti alloy. (Reannouncement with new availability information)
Technical Report
·
OSTI ID:189771
Al-Zn alloy and multilayer TiN/Ti/TiN thin coatings were deposited on DU-0; 75Ti alloy specimens by a cathodic arc plasma physical vapor deposition process. The quality, soundness and adhesion of the coatings to the substrate were evaluated by automatic scratch testing, in combination with optical and scanning electron microscopy examination of the scratch morphology. The galvanic corrosion behavior of DU-0.75Ti alloy coupled to the coated alloys and aluminum alloy 7075-T6 was also investigated by electrochemical tests in a 0.5 N NaCl aqueous solution.
