Abstract:

The candidate base metals were reviewed for the hydrofoil application. Four materials were chosen for this evaluation. They were 17-4PH and 15-5PH stainless steels, HY 130 steel and Ti 6Al-2cb-1Ta-1Mo titanium. Fracture and corrosion fatigue data are being obtained on these materials as part of an on-going program and the available data is reported. Since the HY type alloys require a corrosion protective coating, a screening evaluation of coating systems has been conducted. Four coating systems have been selected for futher testing including their effect on the corrosion fatigue and fracture properties of the HY 130. Details of the screening tests are reported.
