The damage to the shaft sleeve is mainly caused by the extrusion force of the expansion sleeve and the compound mechanical force on the shaft diameter surface during long-term operation. In severe cases, it may cause deformation, which in turn causes the mechanical expansion and tightening strength to fail to meet the requirements. With the retraction force, a fit gap appears between the sleeve and the spindle, causing wear of the sleeve. Since the value of the bushing components is relatively large and the replacement requires a large amount of manpower and material resources, surface repair is a matter of great concern to the machinery industry.
As one of the technologies for strengthening and repairing metal surfaces, thermal spray processing technology can not only be applied to equipment maintenance, but can also be used to strengthen and protect the surface of parts. On the shaft sleeve, Tianmeng Company uses plasma spraying technology and selects oxide ceramics, such as chromium oxide, titanium oxide, aluminum oxide and other materials. The ceramic coating is sprayed on the surface of the shaft sleeve, which has heat resistance, corrosion resistance, and corrosion resistance. Wearability, insulation, heat insulation and other properties extend the service life of the bushing.
