Topographies are one of the challenges for the development of the metal additive
manufacturing promising technique. The article investigates multi scale topographies (from …

This study deals with the analysis and usefulness of the material ratio curve. The parameters
obtained from this curve are presented. The most popular of these parameters include two …

Running-in plays an important role in the steady-state performance of mechanical elements.
It is a transient process involving a complex interaction between friction, lubrication …

Accurate wear measurement is an important task. In this paper, measurements of wear
levels within the limits of the original surface topography using profilometric methods were …

The paper investigates the running-in of hardened steel surfaces under mixed lubrication
conditions. Pairs of surfaces of both equal and differing hardness were loaded together …

A ball-on-disc machine was employed in a highly idealised setting to study the interplay
between oil film formation and surface irregularities in single-sided rough elasto …

A ball-on-disc machine was operated under conditions relevant to heavily loaded gears.
Various levels of isotropic surface finishes were evaluated to reveal the influence on elasto …

The variation of three-dimensional topographies of GCr15 steel and H70 brass during wear
process was studied by multifractal method. A multi-stage test method was proposed to …

The use of appropriate lubricant additives can reduce surface damage, extend machine
lifetimes, improve machining accuracy, and reduce power consumption. In this study, the …

Wear measurement of rolling contact during running-in is challenging because the mass
loss is minor and the wear track change is almost undetectable. To overcome this limitation …
