普通碳素钢经热浸镀铝、铝合金后将具有较高的耐蚀性和良好的抗高温氧化性能,为了进一步提高其耐热性,对热浸镀稀土铝合金进行了试验研究,试验数据表明,A3钢经热浸镀稀土铝合金后,不仅改变了其镀层组织形态,而且其耐热性也有明显提高.在相同条件下对1Cr18Ni9Ti奥氏体耐热不锈钢进行了抗高温氧化性能试验,试验结果表明,A3钢经热浸镀稀土铝合金后,其耐热性可与1Cr18Ni9Ti奥氏体耐热钢相比. Ordinary carbon steel by hot-dip aluminum, aluminum alloy will have high corrosion resistance and good resistance to high temperature oxidation, in order to further improve its heat resistance, the hot-dip galvanized rare earth alloy was tested, the test The results show that the A3 steel has not only changed the morphology of the coating but also improved the heat resistance of the A3 steel after hot-dipped rare earth aluminum alloy.At the same conditions, the high temperature oxidation resistance of 1Cr18Ni9Ti austenitic stainless steel was tested , The test results show that, A3 steel by hot-dip rare earth aluminum alloy, the heat resistance and 1Cr18Ni9Ti austenitic heat-resistant steel compared.
