다층 박막의 온도상승에 대한 마이크로 트라이볼로지적 조사
Micro-Tribological Investigation for Temperature Rise in Multi-layered Thin Films
- 발행 : 2000.04.20
초록
The study deals with the development of a computational procedure for evaluating the temperature rise in dry and lubricated multi-layered contacts of head/disk interface. A transient computational model with a transformed rectangular computational domain is utilized. A model and a computational method for micro-contact with sub-lubricated zone, including friction heat generation, have been presented. The model was applied, taking full account of the changes in contact area and contact load due to frictional heating. The computational distribution of temperature is obtained with the analytical findings for various composition and contact conditions. Especially, a rapid rise (
