Beschreibung
Zusammenfassung:	The utility model relates to a wear-resistant steel and copper composite shaft sleeve, which comprises a steel-based sleeve layer as an outer ring and a copper-based sleeve layer as an inner ring, wherein a nickel-based wear-resistant layer is composited in the inner ring, namely the copper-based sleeve layer, and the thickness of the nickel-based wear-resistant layer is 0.2-1 mm. According to the wear-resistant steel and copper composite shaft sleeve, the nickel-based wear-resistant layer is composited on the inner wall of the steel and copper composite shaft sleeve, and a nickel-based material has the stronger wear resistance, so that the wear resistance of the shaft sleeve is greatly improved; the hardness of the inner wall of the shaft sleeve can be increased from average 105 HV to average 605 HV or more, so that the service life of the shaft sleeve is prolonged.
