NiAl alloyed aerofoil had been tested about cavitation damage in contraction-diffuser cavitation abrasion experimental water tunnel, the upper surface of cavitation damage aerofoil had been observed with SEM.
在收缩-扩散型空蚀磨损试验水洞中对NiAl合金翼型进行空蚀破坏试验,使用扫描电镜(SEM)对受空蚀破坏的翼型上表面进行了观测,结果表明翼型上表面有大量的空蚀针孔出现,并随着试验时间的不断延长而扩展成空蚀坑,蚀坑内有微裂纹出现,蚀坑间也出现了微裂纹,从而导致蚀坑的扩展和表面材料的去除。
补充资料:婺元二仙洞
二仙洞洞口海拔高程373米,与双龙洞同为双龙溶洞群中最低一层溶洞。发育在距今2.8亿年前二迭纪的石灰岩地层中。为一座地下河溶蚀侵蚀型多层溶洞系统。洞中有三层溶洞,二层地下河及五条廊道,五座大厅等组成,岩洞特征叹为观止。石花、石笋、石钟乳、石幔、瀑布、等景观令人目不暇接,特别是洞内天然形成的大峡谷及由生物藻类形成晶营剔透的石花,在全国溶洞景观中都属罕见。实为旅游休闲、科学探险、寻道访仙的千古胜地。
