Wear Mechanism of Silicon Nitride = 질화규소의 마모기구

국문 초록 (Abstract)

순수한 paraffin oil을 윤활유로 한 HIPping한 질화규소의 마찰과 마모거동은 sliding speed, normal load와 sliding time에 대하여 조사하였다. subsurface damage에 의해 생긴 mild에서 severe wear로의 전이는 이 실험조건에서 관찰되지 않았다. 이 실험의 결과에서, polishing process와 plastic deformation은 paraffin oil을 윤활유로 한 silicon notride에서 중요한 기구이다. 때때로, wear track에서 elongated grain의 흔적이 나타났다. 또한, 입자의 pull-out은 wear mode의 일부이다.

The friction and wear behavior of HIPped silicon nitride lubricated with a purified paraffin oil has been investigated as a function of sliding speed, normal load, and sliding time. A transition from mild to severe wear caused by subsurface damage was not observed in the investigated test condition. On the basis of experimental results, polishing process and plastic deformation is the predominant mechanism in silicon nitride lubricated with paraffin oil. Occasionally traces of elongated grains in the wear tracks were revealed. Grain pull-out is also a partial wear mode.
