Simulation Research on Diesel Scuffing Fault Based on Tribo-dynamics

Shiyou jixie, 2017
The severe dry friction caused by the damage of the diesel engine piston, piston ring and cylinder liner lubricating oil film could result in diesel scuffing fault, leading to serious consequences. To address the issue, the oscillating characteristics of

Identification of scuffing process: Surface plastic deformation and fracture.

, 1997
Scuffing is generally recognized as a form of surface damage in lubricated sliding. Scuffing damage is not evident until a loud noise and a sudden jump of friction or a seizure occurs.

Simulations of Scuffing Based on a Dynamic System Model

, 2002
Scuffing, a major cause of failure in automobile engines, is considered as a dynamic process in this study. Local adhesions may occur randomly in lubricated contacts due to the existence of asperity contact and breakdown of lubricating films.

DETERMINATION OF POSSIBLE REASONS OF FORMATION OF DEFECT «MICROPITTING» IN HARD-ALLOY DIE INSTRUMENT IN THE PROCESS OF WIRE DRAWING

Литьë и металлургия, 2011
It is established that during operating time in the working channel of die along with uniform scuffing the stable wear occurs as a result of welding of metal particles to die material, what leads to formation of separate micropockets.

Zużycie typu scuffing w parach tribologicznych w ruchu oscylacyjnym

, 2016
The surfaces of the friction pairs in oscillatory motion are exposed to the complex wear processes. Scuffing is a specific wear process, which comprises abrasive and adhesive wear.

Paper 3: An Experimental Determination of the Temperature at Scuffing

, 1967
Since the publication of Blok's critical temperature hypothesis, much of the test data produced from research into scuffing of gears and discs has given support to the concept, whilst more fundamental work has extended the physics of lubricant breakdown.

Research on the running-in scuffing of aviation spiral bevel gears based on measured analysis of surface integrity parameters

Jixie chuandong
ObjectiveThe primary failure modes of aviation spiral bevel gears include tooth surface scuffing, wear, and scoring. Current evaluation methods for these failures neglect the influence of surface integrity parameters, making it difficult to accurately ...

Surface speeds and scuffing.

, 1994
Scuffing is a severe form of surface damage which limits the performance of lubricated sliding machine components. It has no generally accepted criterion, although recent advances in theory and experiment suggest failure is history dependent.
