Abstract : This report documents the second phase of research conducted to select, test, and evaluate protective coating systems for the Navy's MK 48 Torpedoes. Phase 1 of the research evaluated nine coating systems at different thicknesses and applied on different pretreated substrates. These results are documented in USA-CERL Technical Report M-329. The Phase II program tested 10 additional coating systems, including conventional paint type coatings, powder systems, and ceramics. Testing evaluated the coatings adhesion properties and their resistance to impact, gouging, and corrosion. The cumulative results of Phase I and II and forthcoming Phase III will provide critical inputs to determine the most effective protection to the MK 48 Torpedo. Phase I and II results indicate a powder epoxy is the best system tested to date. Keywords: Torpedoes, Protective coatings, Aluminum.
