The Effect of Surface Additives on the Oxidation of Chromia-Forming Alloys

摘要: Abstract The influence of the surface application active elements on composition, morphology, adherence, and growth rate oxide scales formed during high temperature exposure has been investigated. were applied as aqueous solutions nitrate salts that subsequently transformed into oxide. used were: Y, Ce, La, Hf, Ca, Zr. chromia-forming substrates AISI 304 310 stainless steels IN 738, a nickel base alloy. To determine effect minor alloying in doping effect, Y was to three alloy modifications 304. presence or absence Mn Si corrosion behavior determined. Several different techniques which technique most beneficial barrier scale. La found enhance oxidation resistance commercial stainles...
