Hydraulic Method of Protecting Turbines From Cavitation Erosion. (in Russian) K. K. Shal’nev. l.estnik A kademiiNauk.SS.SH, V. 25, IlO. 8, ALlg. Igjj, p. jO-52. Technological methods of protection involve use of high-alloy metals in the building or repair of turbines and turbine parts. However, the hydraulic methods produce better design and smoother, stream-lined parts. Diagrams.

Metal Transfer and the Wear Process. 1L1.Kerridge. Physical Society, Proceedings, V. 68, no. 427B, July 1955, p. 400-407. .\ radioactive, annealed steel pin rubbing against a hardened steel ring is used to compare the amount of wear with the amount of metal transferred fromone surface to the other bywelding. Usingacombinationof radioactive and inactive test-pieces, the rate of transfer to the ring in the equilibrium condition was estimated and found to be the same as the wear rate of the pin.
