摘要: Rare earth organic compounds can provide an environmentally safe and non-toxic alternative to chromates as corrosion inhibitors for some steel aluminium applications. For lanthanum 4-hydroxy cinnamate offers protection reduces the susceptibility hydrogen embrittlement. Recent work has also indicated that it inhibits of in environments containing high levels carbon dioxide. alloys, cerium diphenyl phosphate provides excellent inhibition chloride environments, susceptibly stress cracking. Furthermore, both alloys filiform be suppressed when rare inhibitor are added pigments polymer coatings. The observed thought due synergistic effects between parts these novel compounds, related various species may present complex chemical conditions develop solut...
