High density low pressure plasma sprayed focal tracks for X-ray anodes

摘要

This invention involves the application of dense, metallurgically bonded deposits of tungsten and tungsten rhenium coatings onto preformed based x-ray anodes to be used as focal tracks. The coatings are applied by low pressure DC plasma spraying. The invention also includes heat treatments that further densify the as-applied coatings improving their suitability for use as focal tracks.
