| 摘 要： | 通过对多种耐热不锈钢进行硼砂浴腐蚀及抗氧化试验,研究了各种耐热不锈钢在硼砂浴中的耐腐蚀性及高温抗氧化性。研究结果表明,材料中元素的种类及含量对硼砂浴炉用金属材料的使用寿命有较大影响,其中Ni、Cr元素对材料的耐蚀性及抗氧化性起着决定性作用。材料中Cr含量在20%左右及Ni含量在35%左右时得到最佳的耐蚀性。Cr含量与Ni含量之和不小于45%的材料的高温抗氧化性符合硼砂浴的使用要求。耐热不锈钢的腐蚀主要集中在硼砂浴与空气的交界面处,其他位置腐蚀较弱。硼砂浴中Na2O和B2O3的存在加速了耐热不锈钢的腐蚀。这些研究结果为硼砂浴用坩埚及工夹具的选材提供了依据。

| Abstract: | According to the test of borax bath corrosion and oxidation resistance of many kinds of heat-resistant stainless steel,the corrosion resistance in borax bath and the oxidation resistance of heat-resistant stainless steel at high temperature were discussed.The results show that the life of material for salt-bath furnace largely depends on the element types and percentage in material,especially,Ni and Cr play a key role in the corrosion resistance and oxidation resistance.It has the best corrosion resistance ... |
