| 1. A method for the production of a rotary anode for X-ray tubes, comprising:
providing a base;
pre-heating the base;
using low pressure plasma to spray material as a focal track layer on to the base, including use of at least one plasma gun
and one or more auxiliary heating sources to maintain even heating of the base and to retain a desired temperature of the
base during the low pressure plasma spray.
