| 摘 要： | 针对风电机组在生命周期内始终受到盐雾、湿热环境影响的问题,研究了发电机中永磁体在海洋盐雾环境下的性能变化.通过盐雾腐蚀试验,模拟发电机用N38SH永磁体的服役环境,研究其在盐雾腐蚀条件下磁性能的变化,为海上风电机组永磁体的保护提供理论依据.试验结果表明,无论有无镀层保护,盐雾腐蚀将极大程度影响永磁体的磁性能,特别是在剩余磁感应强度和矫顽力等性能指标下降较多时,需要专门的保护措施.

| Abstract: | Supersonic gas atomization technique is introduced to fabricate the rapid solidified Zn-Al alloys powder. The Zn-Al alloy coating on the surface of the magnesium alloy is prepared by utilizing cold spray technique with rapid solidified Zn-Al alloy powder, and the wear behavior of coat is studied by the test. The results show that the coating has good wear resistance, where the wear weight loss is 52% and 85% less than that of extruded AZ91D alloy at the condition without and with lubrication, respectively. The wear failure form of the coating is agglutination abrasion and partly rust abrasion. |
