磁気ヘッドスライダ上でのPFPE潤滑剤の熱分解挙動の観察

抄録

We successfully demonstrated the availability of TOF-SIMS (Time of flight-secondary ion mass spectroscopy) in studying the thermal decomposition of the lubricant film on magnetic head slider under heating in the vacuum chamber of TOF-SIMS. By comparing the positive mass spectrum of wide range, we found that the molecular weight distribution of lubricant changed by heating and we confirmed that the thermal decomposition of the lubricant could be accelerated by the catalysis of Al₂O₃.
