微动磨蚀是磨损、疲劳及腐蚀叠加的故障，常引起构件远在设计极限之下就产生失效。这是一种随着时间推移而产生的失效，因此，对老龄飞机来说，尤其应当引起注意。由微动磨蚀引发的飞机事故由微动磨蚀引起的飞机事故不少，下面只是其中几个事例。·一架直升机因活塞发动机... Fretting wear is wear, fatigue and corrosion superposition of the failure, often causing the components far below the design limit to produce failure. This is a failure that has occurred over time and, as a result, particular attention should be paid to older aircraft. Aircraft Accidents Caused by Fretting Abrasion There are quite a few aircraft accidents caused by fretting and abrasion, and here are just a few examples. · A helicopter due to piston engine ...
