| Abstract: | The cavitation and its damage are ticklers in the course of running,maintenance and management of centrifugal pumps. The necessary protection techniques must be used. The traditional protection techniques are improving structures of pumps,ameliorating its running conditions and using materials against cavitation. The paper expounds the surface protection techniques such as surface chemical heat treatment,heat spray-daubing technology,alloy powder for spray-welding and laser cladding,etc. The other protection technology and progress are given also. |
