Antioxidation Properties of Zinc Dialkyldithiophosphate in the Presence of Organic Oxides.
Journal of The Japan Petroleum Institute, 1995 酸化物を含む潤滑油に酸化防止剤 (以下AO) を追加添加しても期待どおりの効果が見られないことがある。この現象を解明するためにモデル酸化物 (以下MO) を加えたヘキサデカン (以下HD) を試料油として酸化試験を行い, AOの性能を誘導期間法で評価した。異なるタイプのAOに対してアルデヒド (以下RCHO) が最も悪影響を及ぼすことが判明した。RCHOの影響の詳細を知るためにジアルキルジチオリン酸亜鉛 (以下ZDTP) とRCHOの反応を31P核磁気共鳴分析 (以下31P-NMR分析) で追跡して以下のことを明らかにした。(1) RCHOはZDTPの分解を促進し, その結果誘導期間が減少する。(2) RCHOとZDTPの反応は酸素中で進行する。(3) 過酸化物とZDTPの反応は速やかに進行する ...

Dynamics of solid dispersions in oil during the lubrication of point of contacts. Part 2: Molybdenum disulfide [PDF]
A Hertzian contact consisting of a steel ball in contact with a glass disk is lubricated with MoS2 dispersions and observed by optical microscopy at various slide/roll conditions. In general the behavior of MoS2 and graphite are similar.
