摘要：A hardened wear spot on a textile element is formed by applying high energyheat to a selected small area of the element which has been previously hardened andtempered to provide the proper spring characteristics for an operating textile element.The intensity and time of application of the high energy heat and the cooling after heatcut-off are carefully controlled to provide a small area of full hardness which iscompletely separated from the remaining tempered portion by a buffer zone of lesshardness than either the tempered portion or the full hardness area.
The new textile element made by this new method is a textile element with the majorportion having a predetermined spring characteristic for an operating textile element. Asmall area of full hardness is located at a predetermined location to provide wearresistance. A buffer zone having less hardness than either the full hardness area or themajor tempered portion completely separates the full hardness area from the majorportion.
