ABSTRACT:
A coating of at least 71% by weight molybdenum as applied to the steel base body of a worm or screw for a plastifier or extruder for plastic materials and synthetic resin by introducing the coating material into a laser beam and directing the thus melted coating material and the laser beam onto the surface of the worm or screw to be coated. The melt-metallurgical bond is formed between the coating without distortion or crack formation of the base body.
