1979年10月在荷兰 Petten 召开了一次高温及有腐蚀环境中高温材料行为研究的国际性会议。会上 Corti C.W.等发表了一篇用铂族元素作合金元素,加入到新型镍基超耐热合金中,以提高合金在高温下的机械强度、抗氧化和抗腐蚀能力以及高温相结构的稳定性的文章。目的是在寻求一种更好的航空燃气透平引擎材料。在这种工作条件下,要求材料在高温下的强度要高,又要能抵抗燃料燃烧产生的气体中所含硫化物及氯化钠之类物质的腐蚀,又要能抗氧化。而这些氧化和腐蚀作用,往往是随温度的增加而加剧的。
October 1979 held in Petten, The Netherlands, an international conference on the behavior of high temperature and high temperature materials in corrosive environments. At the meeting, Corti CW et al. Published an article using a platinum group element as an alloying element added to a new nickel-based superalloy to improve the mechanical strength, oxidation and corrosion resistance of the alloy at high temperatures and the stability of the high-temperature phase structure Sexual articles. The aim is to seek a better aviation gas turbine engine material. Under such operating conditions, the material is required to have a high strength at high temperature and also to resist the corrosion of sulfides and sodium chloride contained in the gas generated by the combustion of the fuel, as well as to be resistant to oxidation. These oxidative and corrosive effects are often exacerbated by temperature increases.
