Effect of Molecular Structure of Oil on the Film Thickness during Rolling
Tribology Online, 2009 In recent years, metal working oil is required to have lower viscosity and higher lubricity than ever. Controlling oil film thickness is one of the most important in metal working.

Ultrasonic Phase and Amplitude and the Measurement of Oil Film Thickness
World Tribology Congress III, Volume 1, 2005 The reflection of ultrasound at an oil film can be used to determine the film thickness. A thin oil film reflects less ultrasound than a thick film. When the film is thin there is a simple relationship between oil film thickness and the proportion of the wave amplitude reflected.

Oil-film extinction coefficient inversion based on thickness difference
Optics Express, 2022 The extinction coefficient of oil films on the sea surface was inversion using a physical model based on two-beam interference and the equal-thickness difference method. The coefficient is simplified to a quadratic equation in one variable related to oil-film thickness and incident angle and wavelength of light. Through a laboratory-simulated oil spill

ANALYSIS OF LOAD CAPACITY AND TEMPERATURE FIELD OF SPHERICAL HYBRID SLIDING BEARINGS (MT)
Jixie qiangdu, 2023 The oil film temperature of the spherical hybrid sliding bearings would increase due to the friction and shear of the lubricating oil at high speed or super high speed, which leads to the thermal deformation of bearing and rotor.
