Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018 Two oil‐soluble organic titanium compounds (OTCs) such as titanium dialkyldithiocarbamate (TiDDC) and sulfurized titanate (TiS) were synthesized and identified by Fourier‐transform infrared spectroscopy (FTIR). The antiwear and extreme pressure properties of TiDDC or TiS with borate ester containing nitrogen (BNO) additive in mineral base oils were ...

Elucidating the Friction Catalytic Lubrication Mechanism of Ag Nanoparticles Loaded on MOFs
Advanced Materials Interfaces, Volume 12, Issue 17, September 8, 2025.A novel Ag@Co‐BDC nanocomposite lubricating additive is successfully synthesized, which effectively promoted interfacial tribochemical reactions to form a protective tribofilm during friction, resulting in a 16.7% reduction in friction coefficient and a 61.5% decrease in wear rate for base oil.

Surface Analysis of Chain Joint Components after Tribological Load and Usage of Antiwear Additives
Conference Papers in Science, Volume 2015, Issue 1, 2015., 2015 Wear in chain joints leads to an increased clearance and thus an elongation of the entire chain which determines the lifetime of the chain. This particularly applies for chains that are used in timing chain drives. The aim of this study was to investigate especially the influences of lubricant additives and a contamination with carbon black on the ...

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 ...
