NITRIDING AND CARBONITRIDING OF TITANIUM METAL AND ITS ALLOYS

摘要

The treatment of nitriding titanium and titanium alloys in dissociating ammonia and nitrogen gas has been completed. Hard adherent surfaces have been obtained. Evaluation of physical properties of resultant nitrided titanium and titanium alloy specimens such as hardness, adherence, structure, impact and tensile strength are included, a complete resume of the process is included.nThe carbonitriding of titanium and titanium alloys was investigated. Mixtures of propane, air and ammonia gas were utilized in all experiments.nThe effect of temperature, time and gas mixture on hard ness and case characteristics were studied.
