| 4 | Does laser surface texturing really have a negative impact on the fatigue lifetime of mechanical components?显示文摘Laser surface texturing(LST)has been proven to improve the tribological performance of machine elements.The micro-scale patterns manufactured by LST may act as lubricant reservoirs,thus supplying oil when encountering insufficient lubrication.However,not many studies have investigated the use of LST in the boundary lubrication regime,likely due to concerns of higher contact stresses that can occur with the increasing surface roughness.This study aims to examine the influence of LST on the fatigue lifetime of thrust rolling bearings under boundary lubrication.A series of periodic patterns were produced on the thrust rolling bearings,using two geometrically different designs,namely cross and dimple patterns.Base oil ISO VG 100 mixed with 0.05 wt%P of zinc dialkyldithiophosphate(ZDDP)was supplied.The bearings with cross patterns reduce the wear loss by two orders of magnitude.The patterns not only retain lubricant in the textured pockets but also enhance the formation of an anti-wear tribofilm.The tribofilm generation may be improved by the higher contact stresses that occur when using the textured surface.Therefore,in contrast to the negative concerns,the ball bearings with cross patterns were instead found to increase the fatigue life by a factor of three. | Chia-Jui HSU Andreas STRATMANN Simon MEDINA Georg JACOBS Frank MÜCKLICH Carsten GACHOT | 2021 | Friction2021，9，6： | 3 |
| 5 | Influence of structural depth of laser-patterned steel surfaces on the solid lubricity of carbon nanoparticle coatings显示文摘Carbon nanoparticle coatings on laser-patterned stainless-steel surfaces present a solid lubrication system where the pattern's recessions act as lubricant-retaining reservoirs.This study investigates the influence of the structural depth of line patterns coated with multi-walled carbon nanotubes(CNTs)and carbon onions(COs)on their respective potential to reduce friction and wear.Direct laser interference patterning(DLIP)with a pulse duration of 12 ps is used to create line patterns with three different structural depths at a periodicity of 3.5μm on AISI 304 steel platelets.Subsequently,electrophoretic deposition(EPD)is applied to form homogeneous carbon nanoparticle coatings on the patterned platelets.Tribological ball-on-disc experiments are conducted on the as-described surfaces with an alumina counter body at a load of 100 mN.The results show that the shallower the coated structure,the lower its coefficient of friction(COF),regardless of the particle type.Thereby,with a minimum of just below 0.20,CNTs reach lower COF values than COs over most of the testing period.The resulting wear tracks are characterized by scanning electron microscopy,transmission electron microscopy,and energy-dispersive X-ray spectroscopy.During friction testing,the CNTs remain in contact,and the immediate proximity,whereas the CO coating is largely removed.Regardless of structural depth,no oxidation occurs on CNT-coated surfaces,whereas minor oxidation is detected on CO-coated wear tracks. | Timothy MACLUCAS Lukas DAUT Philipp GRÜTZMACHER Maria Agustina GUITAR Volker PRESSER Carsten GACHOT Sebastian SUAREZ Frank MÜCKLICH | 2023 | Friction2023，11，7： | 0 |
| 6 | Load dependent microstructural evolution in an as-cast 26%Cr high chromium cast iron during unlubricated sliding显示文摘In the current study,an as-cast 26%Cr high chromium cast iron(HCCI)alloy was subjected to dry-sliding linear wear tests,under different loads.The loads were selected based on analytically computing the critical load(PC)i.e.,the load necessary to induce plastic deformation.The PC was calculated to be 15 N and accordingly,a sub-critical load(5 N)and an over-critical load(20 N)were chosen.The influence of increasing the load during the wear test was investigated in terms of the matrix microstructural behaviour and its ability to support the surrounding carbides.The morphological aspects of the wear tracks,and the deformed matrix microstructure adjacent and underneath the track was analysed by confocal laser scanning microscope(CLSM)and scanning electron microscope(SEM),respectively.No evidence of plastic deformation of the matrix was observed below PC.On the contrary,at loads equal to and higher than PC,the austenitic matrix plastically deformed as evidenced by the presence of slip bands.Electron backscattered diffraction(EBSD)measurements in terms of grain reference orientation deviation,and micro-Vickers hardness of the austenitic matrix indicated a deformation depth of about 40μm at the maximum applied load of 20 N.The active wear mechanisms during sliding were a combination of both adhesive and abrasive wear,although increasing the load shifted the dominant mechanism towards abrasion.This was primarily attributable to the increased propensity for carbide cracking and fracturing,combined with the inability of the hardened austenitic matrix surface and sub-surface to adequately support the broken carbide fragments.Moreover,the shift in the dominant wear mechanism was also reflected in the wear volume and subsequently,the wear rate. | U.Pranav NAYAK Sebastian SUÁREZ Valentin PESNEL Frank MÜCKLICH María Agustina GUITAR | 2022 | Friction2022，10，8： | 0 |
