Document Type and Number:
WIPO Patent Application WO/2005/031125
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a valve sheet to be fitted on an assembly support part disposed at an intake vent of aluminum alloy cylinder head, which valve sheet inhibits galvanic corrosion. [MEANS FOR SOLVING PROBLEMS] There is provided iron base valve sheet (10) to be fitted on assembly support part (13) disposed at intake vent (6) of aluminum alloy cylinder head (2), which valve sheet is comprised of an iron-aluminum material. This iron-aluminum material contains an Al component in an amount of 15 to 23 wt.%. The potential difference between the assembly support part (13) of the cylinder head (2) and the valve sheet (10) is minimized so as to attain inhibition of galvanic corrosion.
