Depletion of the Lubricant from Lubricant-Infused Surfaces due to an Air/Water Interface
Langmuir, 2021Lubricant-infused surfaces (LIS) have emerged as an innovative way to combat several modern challenges such as biofouling, ice formation, and surface drag. The favorable properties of LIS are dependent on the presence and distribution of a lubricant layer coating the underlying substrate.

Air-Lubricated Pneumatic Workbench
Applied Mechanics and Materials, 2010The air-lubricated pneumatic workbench introduced in this paper is used in rotary ultrasonic machining which are widely used to machine hard and brittle materials. It is necessary to use special ultrasonic machine tool for rotary ultrasonic machining in the traditional ultrasonic machining, limiting the application of ultrasonic machining.

The Research on Oil-Air Lubrication and Oil Lubrication in the Sliding Bearing
Key Engineering Materials, 2013In order to study the effect of oil-air lubrication on traditional sliding bearing, the experiments oil-air lubrication and oil lubrication have been done by using friction-abrasion testing machine. By means of measuring friction moment, the temperature rise of two different lubrication systems in the same conditions and studying the friction moment ...

NEW CONCEPT OF AIR LUBRICATION
Scientific Lubrication, 1961THE Aero-Space Division of the Boeing Airplane Company, Seattle, Wash., U.S.A. has recently announced the development of a new type of externally pressurised step bearing whose load-carrying shaft spins freely on a cushion of compressed air. The This new concept in the use of air as a bearing lubricant is expected to result in wider applications for ...

Cylinder lubrication of AIR COMPRESSORS
Scientific Lubrication, 1949There are two principal reasons why it is disadvantageous, and frequently dangerous, to over-lubricate the cylinders of air compressors, firstly fire risk and secondly contamination of air with oil vapour. Control of oil feed will prevent any likelihood of explosive fires but it may be necessary to incorporate special oil vapour filters to prevent ...

Industrial Lubrication and Tribology, 1972
OF the two types of thrust bearing employing, respectively, slot and orifice feed, investigations at the City University have shown that if steam is admitted as a lubricant, the slot configuration does not suffer from excited vibration in the form of pneumatic or steam hammer. Typical orifice‐fed and slot‐fed air type bearings are shown in Figs.

Paper 10: Lubrication of Air Compressors
Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1969There is an increasing use of pneumatic equipment in production and process industries and reliability of equipment in these industries is of paramount importance. The failure of an air compressor due to deficiencies in the lubricant can be very costly. In this paper important aspects of lubricant performance are discussed. The differences between the

Rough Air-Soft Elastohydrodynamic Lubrication
Applied Mechanics and Materials, 2013This paper presents the effects of rough surface air-soft elastohydrodynamic lubrication (EHL) of rollers for soft material under the effect of air molecular slip. The time independent modified Reynolds equation and elasticity equation were solved numerically using finite different method, Newton-Raphson method and multigrid multilevel methods were ...

Air-lubrication of magnetic disk sliders
Journal of Magnetism and Magnetic Materials, 1993Steady-state and dynamic flying of a self-acting magnetic disk slider over a hard disk are considered. Some tasks for computations are formulated and the possibilities of developed numerical codes are illustrated. Numerical results of dynamic flying over a disk surface with an obstacle are in agreement with experimental data.
