A surface force apparatus (SFA) has been used to determine film thickness and film properties of adsorbed neutral and basic diisobutyl zinc dithiophosphates (ZnDTPs) on cobalt surfaces. Sliding experiments were also carried out and film characteristi

Overbased detergents and ZnDTPs form insulating boundary lubrication films. Electrical contact resistance (ECR) is therefore a convenient method of monitoring boundary film changes in a sliding contact. Separately, ZnDTPs and overbased detergents rap

Zinc dithiophosphates (ZnDTPs) have been used extensively as anti-wear agents for over 30 years. The mechanism of action of these remarkable materials is not fully understood. In particular, the molecular composition of the antiwear film produced by

Zinc dithiophosphates (ZnDTPs) have been used as the main antiwear additive in automotive engine oils for many years. They consist of mixtures of neutral and basic ZnDTP salts. Until now, the relative wear performance of the neutral and basic ZnDTP s

Soot-related viscosity increase has long been recognised as a potential problem in diesel engine operation. Proposed emissions regulations have led to investigations of changes in combustion to reduce soot emissions. Some of these changes, though eff

Inelastic electron tunneling (IET) spectra of pure neutral and basic isopropyl, isobutyl, and p-t-octyl phenyl ZnDTPs are reported. These pure compounds were specially synthesized in order to examine the IET spectra of the neutral and basic ZnDTP sal
