Behavior of Ni-Cr-Si Coating Alloys in Na sub 2 SO sub 4 , V sub 2 O sub 5 , and Mixed Salt Hot Corrosion. Final Report

摘要

This report describes the results of a program to select coating alloys that are resistant to vanadium- and sulfate-induced hot corrosion and solid particle erosion in the 700 to 900 exp 0 C temperature range. Test materials, methods, and results are discussed. The principal alloy coatings that were tested were high-chromium, nickel-base alloys with additions of silicon, aluminum, and tantalum.
