<p>#CMT# #/CMT# Activating and/or modifying a surface using a gas flame produced by a gas mixture, which includes a fuel gas and a gas containing at least oxygen, preferably air, and/or activating and modifying the surface using plasma containing gas, comprises adding, preferably admixing water to the fuel gas and/or to the plasma, where the amount of water, respectively (0-30 vol%, preferably 0-3 vol%, based on the gas containing at least oxygen, which is included in the gas mixture, and/or 0-100 vol%, preferably 0-3 vol%, based on the gas contained in the plasma) added is adjusted in a defined manner. #CMT# : #/CMT# Activating and/or modifying a surface using a gas flame produced by a gas mixture, which includes a fuel gas and a gas containing at least oxygen, preferably air, comprises adding, preferably admixing water to the fuel gas, the gas containing at least oxygen or to the gas mixture, where the amount of water (0-30 vol%, preferably 0-3 vol%, based on the gas containing at least oxygen, which is included by the gas mixture) added is adjustable or adjusted in a defined manner; and/or activating and modifying the surface using plasma containing gas, comprising adding, preferably admixing water to the plasma, where the amount of water (0-100 vol%, preferably 0-3 vol%, based on the gas contained in the plasma) added is adjustable or adjusted in a defined manner. An independent claim is also included for: coating the surface using the gas flame containing an organo-metallic precursor produced from the gas mixture including the fuel gas and the gas containing at least oxygen, preferably air, comprising adding, preferably admixing water to the precursor, where the amount of water (0-30 vol%, preferably 0-3 vol%, based on the air containing in the fuel gas) added is adjustable or adjusted in a defined manner, and/or coating the surface by the gas and the plasma containing the organo-metallic precursor, comprising adding, preferably admixing water to the plasma, where the amount of water (0-100 vol%, preferably 0-3 vol%, based on the gas contained in the plasma) added is adjustable or adjusted in a defined manner. #CMT#USE : #/CMT# The method is useful for activating and/or modifying the surface using a gas flame produced by the gas mixture. #CMT#ADVANTAGE : #/CMT# The method achieves improved process-results, is improved with respect to requiring less technical expense and providing high and constant quality of the coatings, and improves the adhesion strength of the coatings applied on the surface. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Method: The method includes adding defined amount of water to the fuel gas, to the gas or to the gas mixture, or adding water into the fuel gas, or mixing the water with the gas or with the organo-metallic precursor. The method includes initially carrying out a defined dehumidification of the fuel gas, gas and/or the gas mixture by a moisture reducing device. The fuel gas, the gas and/or the gas mixture is/are dehumidified such that defined moisture content is adjusted. The method includes dehumidifying the fuel gas, gas and/or the gas mixture, before or after the water is added to the fuel gas, to the gas and/or to the gas mixture. The fuel gas, gas and/or the gas mixture is/are dehumidified and no water is added to the fuel gas, gas and/or the gas mixture. The activating and modifying the surface by the plasma containing gas or by the plasma containing the gas and the organo-metallic precursor, is carried out in presence of atmospheric pressure. #CMT#EXAMPLE : #/CMT# No suitable example given.</p> |
