HYDROFOIL MATERIALS RESEARCH PROGRAM

Abstract

Sixty materials were studied to determine their suitability for use in construction of high performance hydrofoils and struts. Of these, seventeen materials were given screening tests for susceptibility to sea water corrosion and impingement erosion, and for comparisons of mechanical and fabrication properties. From this work HY-130 low alloy steel and Ti 7Al-2Cb-1Ta titanium were selected for development of design and fabrication data. The HY 130 suitably protected from the sea water environment with a neoprene coating is available for use. The titanium alloy shows many advantages but must have alloy changes to preclude stress corrosion cracking before economic benefits can be realized.
