| 摘 要： | 分别采取大气等离子(APS)和高速火焰(HVOF)工艺制备Ni-Cr-Al-_Y涂层.对涂覆Ni-C卜Al-Y涂层的高温合金试样的热机械疲劳(TMF)行为进行了研究.结果表明:在相同应变幅下,2种涂层试样都是反相位热机械疲劳(OP TMF)寿命比同相位热机械疲劳(IP TMF)寿命短;在不同应变幅下,试样的热机械疲劳寿命与涂层的喷涂工艺相关.通过断I=I和纵向剖面图的观察分析表明,裂纹的萌生对试样的寿命有很大的影响.

| Abstract: | Gas turbine engine is widely used in industry,marine and aerospace.Its efficiency can be enhanced by increasing inlet gas temperature and reducing heat transfer.To achieve this goal it is important to develop materials with higher melting points.Ni-based superalloy is suitable for vane and blade materials.The properties of superalloy have been improved by directionally solidified and single crystal in last 50 years.But it is limited to develop superalloy with much higher temperature,because the operating te... |
