Rotating anode plate producing method, involves forming base plate sleeve to net shape of anode plate, such that deformation degree to be realized in area of ring shaped tungsten-rhenium-alloy layer is larger than certain percentages

摘要

The method involves forming a base plate sleeve (1) to a net shape of a rotating anode plate. A deformation degree to be realized in an area of a ring shaped tungsten-rhenium-alloy layer (3) is larger than 10 percentages, preferably 30 percentages. The anode plate is recrystallisation-annealed at an annealing temperature above 1500 degrees Celsius, preferably 1700 degrees Celsius over a period of 1 hour, preferably 4 hours.
