In-situ observation of influence of metal types on wear process in dry conditions
2022, WearCitation Excerpt :Other researchers [18–26] likewise showed the evolution of a specific layer with microstructures on the top surface of steel. Especially when scuffing occurs, which is a catastrophic failure [27,28] leading to marked increases in friction and wear, and a clear layer with ultrafine grain crystals is created on the top surface. The evolution process of the specific layer and its structure and influence on wear were investigated.
Fundamentals of ductile cast iron scuffing at the boundary lubrication regime
2015, Tribology InternationalCitation Excerpt :Apart from this fact, it has generally been accepted that the constituent that is necessary but most often insufficient to scuffing in which the lubricated system occurs is the breakdown of the EHL or boundary film. The problem of precise identification of scuffing initiation follows from the fact that none of the specific theories (e.g. [5–9]) describes this process in a universal way; most of these theories concern concrete material pair and applying friction conditions. Some kind of synthesis in this field was carried out by Bowman and Stachowiak [10], who listed several factors conducive (especially in synergic occurrence) to scuffing initiation:
Scuffing tendencies of different metals against copper under non-lubricated conditions
2011, WearCitation Excerpt :The effects of sliding speed, “specific” pressure, vibration, temperature, shape of the contacting bodies, sliding time, gaseous and fluid environments, solid lubricants, type of materials, surface treatment methods, and properties of oxide layers on scuffing were reported. In another review, Dyson [23,24] introduced the concept of ‘friction power intensity’ as a function of sliding speed. He considered that parameter to be the most satisfactory way by which the results from various investigations could be compared, but concluded that scuffing phenomena remain incompletely understood.
Influence of temperature distributions in EHL film on its thickness under high slip ratio conditions
2007, Tribology InternationalCitation Excerpt :Dyson et al. [15] showed an abnormal result that film thickness increased as load increased. Although their discovery was an impressive phenomenon and referred by several researchers, e.g. [16,17], the research on the EHL under pure sliding condition has stopped until 1999, Shorgin et al. [18] carried out experiments using two-disk rotating machine with varying sliding speeds under opposite sliding conditions. They indicated that film thickness was formed under the opposite sliding conditions without damage.

2003, Tribology SeriesLubricated seizure of stainless steel observed by X-ray imaging
2000, WearCitation Excerpt :Seizure is an extreme form of a tribological failure of the materials in relative sliding. Scuffing failure or seizure is influenced by several parameters, such as the normal load, speed, contact temperature, as well as lubricant stability and finally material properties such as ductility, hardness and fracture toughness [1–7,23]. The mechanism governing seizure in lubricated sliding are therefore complex and require in situ studies of such systems to understand the mechanisms governing them.
