Title: Turbine impeller
Inventor: ZEN MUNETOSHI
IPC: C23F13/00
Filed: 2000-04-11
Abstract: PROBLEM TO BE SOLVED: To improve the cavitation resistance without impairing the fatigue strength of a blade surface by using a new material, and to prevent the corrosion by the potential difference at a joint part of welding or thermal spraying. SOLUTION: A blade member 3 made of ferromagnetic martensite stainless steel made of 12Cr is welded and joined to a shroud 1 and a crown 2, made of 403 ss, and a soft steel 5 as sacrificial anode is welded in the vicinity of an impeller end part near an inlet and outlet of water. The martensite stainless steel is optionally thermally sprayed to the blade member of the completed impeller for ferromagnetizing the same. The ferromagnetization of the 12Cr matensite stainless steel increases the damping performance, and effectively improves the cavitations resistance of the blade part by compatibility of the strength and the damping performance and the corrosion resistance, whereby the cavitation damage under the water environment can be prevented, and the corrosion can be also prevented by the sacrificial anode.
