Gas mixture useful in thermal spraying, cutting and/or during surface treatment, consists of a mixture of argon, helium, nitrogen, carbon dioxide and/or hydrogen with hydrocarbon gaseous under normal condition

摘要

The gas mixture comprises a mixture of argon, helium, nitrogen, carbon dioxide and/or hydrogen with hydrocarbon gaseous under normal condition. The mixture consists of doped quantity of nitrogen monoxide, nitrogen dioxide and/or oxygen. The hydrocarbon contains double- or triple bond and is acetylene. The mixture consists of 2-5 vol.% of hydrocarbon related to the total mixture. Independent claims are included for: (1) a method for industrial preparation of a gas mixture; and (2) a device for providing a gas mixture.
