研究了改性后的SUS316在不同氧势和碲蒸气中的腐蚀行为。在氧势⩽−为500kJ/−，碲的蒸气压为8.9×10-4atm的条件下，试样表面形成了双相腐蚀层，主要由碲化铬、碲化铁和氧化铬组成。随着氧势的降低，腐蚀层厚度增加。此外，有碲蒸气腐蚀的样品的吸氧量远大于未经碲蒸气氧化的样品。
Corrosion behavior of modified SUS316 has been studied under different oxygen potentials with tellurium vapor. Under the condition of oxygen potential⩽−500 kJ/mol and tellurium vapor pressure of 8.9×10−4atm, duplex corrosion layers formed on the surface of specimens, which mainly consisted of chromium telluride, iron telluride and chromium oxide. The thickness of corrosion layer was increased with decreasing the oxygen potential. Furthermore, the amount of oxygen uptake in sample corroded with tellurium vapor was much greater than that in sample oxidized without tellurium vapor.
