Abstract Plating rare earth chromium on stainless steel appl ied in hydraulic turbine,by means of the operation converting electrodes periodi cally,was carried out.The plating layer consists of metallic matrix and second p hase particles of rare earth sulphates or carbonates,its thickness is about 0.3m m,its microhardness is from Hv900 to 1000.The results of anodic polarization cur ves indicate that the corrosive resistance of plating layer is 7～8 times to tha t of stainless steel substrates.When an imitating small hydraulic turbine made u p of different materials was rotated in the slurry of 60% water and 40% sands,th e resistance of plating layer to cavitation erosion and abrasion is about 28 tim es to that of stainless steel,and is 10～12 times to that of plasma-nitrided sta inless steel.The results of hydraulic electricity generation indicate the servic e life of plated hydraulic turbine is 3～6 times to that of stainless steel hydr aulic turbine.

Key words: hydraulic turbine cavitation erosion and abrasion plating rare earth chromium
