采用光学显微镜、SEM及EDS等方法,对涂层的冷热疲劳性能和抗磨损性能进行了分析研究,并与当前冶金行业大量使用的电镀NiCo镀层进行对比。
2.
Co based alloy coating was deposited on the narrow side CrZrCu plate of the slab continuous caster with HVOF and the cold-hot fatigue was compared with Co-Ni plating coating.
结果表明:450℃下进行冷热疲劳试验,Co基合金涂层经过113次后,涂层还保持完好无损,未出现任何缺陷,而电镀镀层只能承受37。
2) thermal fatigue
冷热疲劳
1.
Microstructure and thermal fatigue mechanical properties of cast cobalt-base su peralloy K640S were investigated during a number of recycles.
对铸造钴基高温合金K640S进行10次返回处理,研究了母合金和几种不同返回次数返回料的冷热疲劳性能,并进行了金相观察·结果表明:加热到815℃,然后水冷到25℃,保温5min,冷却5s,循环70次时,7返、10返合金首先出现微裂纹·随着循环次数的增加,返回料比新料疲劳裂纹生长快·循环200次时,无论新料还是返回料裂纹长度都达到2mm·随着返回次数的增加,合金中气体及夹杂物质量分数随之增加,枝晶组织越来越发达
3) Cold-thermal fatigue
冷-热疲劳
1.
,but also increases the cold-thermal fatigue resistance and the stability of resisting temper.
通过对3Cr2W8V钢超低温处理试验的研究表明:在常规淬火、回火后进行的超低温改性处理会使合金钢的回火马氏体中析出大量微细的碳化物颗粒,这些颗粒会均匀、弥散地分布在马氏体的孪晶带上;不仅提高了合金钢的强度、硬度等力学性能,同时增加了冷-热疲劳抗力和抗回火稳定性。
4) cold & heat fatigue resisting
耐冷热疲劳
5) cold and hot fatigue property
冷热疲劳特性
1.
The cold and hot fatigue property of PCrNi3MoV roll ring after double quenching has been studied in this article,which described when the heating temperature is in the range of 500-700℃,it has higher plasticity,and when the room temperature is within 450 ℃,the roll ring has higher cold and hot fatigue lifetime.
研究了PCrN i3MoV辊套通过双液淬火后的冷热疲劳特性,指出,当加热温度在500~700℃范围时,PCrN i3MoV辊套具有较高塑性,在室温~450℃温度区间具有较高的冷热疲劳寿命。
6) thermal cold fatigue
冷热循环疲劳
补充资料：冷热嗽
冷热嗽
冷热嗽 病证名。兼感寒热之邪所致的咳嗽。《证治要诀》卷六：“冷热嗽，因增减衣裳，寒热俱感。遇乍寒亦嗽，乍热亦嗽，饮热亦嗽，饮冷亦嗽。宜金沸草散、消风散各一贴和煎，或应梦人参散，或款冬花散、二母散，仍以辰砂化痰丸、八风丹，或四和丸含化。”热重者，用葳蕤汤去川芎加香豉；失音者用《古今录验》续命汤，轻则消风散。参见咳嗽条。
