Abstract:

The purpose of this investigation was to determine if lead sulfide-boric oxide and lead monoxide-silica coatings caused any deleterious effects to metal substrates in the temperature range of 1200 to 1400 F. The substrate material consisted of six panels of 321 stainless steel measuring 2 x 2 x .05 in. After six hours exposure at 1200 and 1300 F, neither the lead sulfide-boric oxide and the lead monoxide-silica coated specimens showed no deleterious effects at the coating-substrate interface. After six hours exposure at 1400 F, however, the lead sulfide-boric oxide and the lead monoxide-silica coated specimens showed a slight intergranular attack on the 321 stainless steel substrate.
