  • Screw for a plastics processing machine, and method of regenerating a screw
    Patent number: 6786630
    Abstract: A screw for a plastics processing machine includes a screw body made of a base material, which is no longer useful as a consequence of wear. A single-ply or multi-ply a buffer layer made of magnetically conductive metallic material is applied onto the crest of the screw body by means of a thermal spraying process, and a wear-reducing coating made of molybdenum or a molybdenum-containing alloy and applied onto the buffer layer by means of a thermal spraying process This provides a simple way of ensuring that the regenerated screw has a long service life and is resistant to heavy loads.
