Abstract

The article presents a new combined technology for use in the renovation of the rotors of screw compressors that increases their reliability and useful life through a combination of different methods of increasing the quality of the surfaces of parts, including: electroerosion alloying, ion nitriding, carburizing by means of electroerosion alloying, non-abrasive finishing, coating with polymer materials, and sulphurizing.
