Influence of PMA on the anti-scuffing properties of AW/EP additives [PDF]
Tribology International, 2022 Scuffing is becoming a quite common failure mode in gears and bearings. It has been shown that AW/EP additives are effective in preventing scuffing, but only if they are able to form a thick tribofilm before encountering severe scuffing-type conditions ...

A new scuffing test using contra-rotation [PDF]
Wear, 2015 The mode of lubricant failure known as scuffing provides a significant design constraint in high sliding gears, cams and metal cutting and forming processes. It is therefore important to have an effective test method to measure the scuffing resistance of

Tribology International, 1975
Abstract Although scuffing is not commonly encountered in service, it influences the design and metallurgy of many machine parts and considerable effort may be required in development to overcome it. The various factors affecting scuffing are described and this lead naturally to a discussion of empirical criteria for predicting scuffing.

Surface transformations in scuffing
Wear, 1974Abstract This paper presents some new information about the nature of the phase changes occurring at scuffing steel surfaces. Transmission electron microscopy has been used to investigate the phases formed. It was found that a fine grained martensite was formed at the rubbing surface, and that immediately below this tempering had occurred.

Abstract Scuffing is the appearance of white wear marks on bottles which are less attractive for consumers and unacceptable for quality products. Full scale trials showed that a scuffing reduction of 100 % can be obtained by applying a post-end coating which lowers the mechanical impact on bottles, thereby doubling ...

Scuffing initiation caused by local starvation in a piston ring cylinder liner contact
Tribology International, 2022 International audienceScuffing is a localized damage process caused by a sudden failure of the lubricating film in a sliding contact. It is associated with an important increase in temperature, friction and vibration.

A new scuffing shock test method for the determination of the resistance to scuffing of coated gears
Archives of Civil and Mechanical Engineering, 2012Abstract An improvement in the scuffing resistance of toothed gears is achievable by e.g. the deposition of thin, hard coatings onto the gear teeth. However, the testing of the scuffing resistance of coated gears requires the application of specialised test methods.

Investigation on Vibration Scuffing Life Curves
The 21st IAPRI World Conference on Packaging, 2018The printing images on products and packaging play an important role in increasing the business value, adding artistic quality, and sending information. During transportation, scuffing of the printing images will emerge due to vibrations and impacts induced by rough roads and vehicles.

Thermodynamics of boundary lubrication and scuffing
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1972Abstract The critical temperature of scuffing found in some lubrication systems is identified with desorption of the surface active agent in the lubricating oil. The thermodynamics of the system are considered and then applied to the chain matching of carrier and additives. Chemisorption takes place more readily on a martensitic steel,

A Solution for Cylinder Wall Scuffing
SAE Technical Paper Series, 1992<div class="htmlview paragraph">A solution for cylinder wall scuffing is researched. By means of the finite element method, a mathematical model to investigate the temperature field and thermal deformation of the piston is established, which can be used for predicting the cylinder wall scuffing in both the design process of a new diesel engine ...
