A method of manufacturing an X-ray tube component, includes diffusion bonding or brazing an anode (2) of rhodium, molybdenum or tungsten to a heat spreader (4) of molybdenum, tungsten, or a composite of molybdenum and/or tungsten. Suitable joint materials (10) for diffusion bonding include gold; suitable joint materials for brazing include an alloy of silver and copper, an alloy of silver, copper and palladium, an alloy of gold and copper or an alloy of gold, copper and nickel. The resulting tube component delivers reliable behaviours and the joint can withstand high temperatures, high temperature gradients, fast temperature changes, extremely high radiation and extremely high electric field, while maintaining good high vacuum properties. |
