AE 센서를 이용한 CrN 코팅의 마찰특성에 관한 연구
An Experimental Study on the Friction of CrN Coated Specimen using the Acoustic Emission Sensor
초록
One of the innovative physical methods that provide insight into the basic processes which determine friction and wear behavior of coated machine tools is acoustic emission (AE). In this study, an investigation of the relation between AE and friction signal produced during repeated sliding test is presented. The material of test specimens is CrN coated 0.2% plain carbon steel with 1 Um thickness. The obtained results demonstrate that AE signal is very related with friction, and AE signal is more sensitive than friction when CrN coated film come off the substrate.
