DEALUMINIZATION OF CAST ALUMINUM BRONZES

Abstract

Effects of microstructure, heat treatment and welding on the corrosion (dealuminization) resistance of cast aluminum bronzes (MIL-B-16033) after six months and one year exposure to flowing sea water are described. Results show that the bronzes are both composition and structure sensitive to corrosion attack. Heat treatment either eliminates or minimizes dealuminization attack; however, welding nullifies any advantages derived from heat treatment. Post-weld treatment can restore corrosion resistance provided proper filler materials are used.
