Abstract The running-in quality and efficiency could be improved by optimizing load, velocity and initial surface roughness of contact surfaces. The relationship between characteristic parameters of running-in attractor and running-in quality was studied. Theoretical analysis and experimental results show that the greater the correlation dimension, the less the enclosing radius, the better the running-in quality. Taking correlation dimension, enclosing radius and running-in time as three objecti...

Abstract Epoxy resins represent an important class of thermosetting polymers that are extensively used in demanding applications like in scratch resistant coatings. Usually fillers, either hard (inorganic) or soft (rubbery), are added. Here we test hard and soft particle-filled epoxy systems in single asperity sliding friction experiments, and analyze the results with the hybrid numerical-experimental approach presented earlier. The focus is on the detailed modeling of the local deformation proc...

Abstract AISI 440B martensitic stainless steels reinforced with up to 15 vol% NbC particles were successfully cast using a vacuum induction furnace. Energy dispersive x-ray spectroscopy, scanning electron microscopy and electron backscatter diffraction techniques revealed that NbC additions led to a slight decrease in the matrix solid solution Cr content, which was found to have a minor impact on uniform corrosion resistance. An ISO 21988 grade Cr27 martensitic eutectic white cast iron was used ...

Abstract In this work, cylindrical roller thrust bearings (CRTBs) with different raceway surface finishes were life tested under rolling-sliding conditions in WEC critical oil. After testing, white etching cracks (WECs) had formed in the raceways of the commercially available standard CRTBs from the test rig manufacturer. However, after embedded abrasive particles were introduced into the raceways (from the lapping process), neither the post-test raceways nor the rollers had WECs, and the damage...

Abstract The low impact abrasion and low stress sliding wear properties of two thermo-mechanically processed austenitic high manganese steels (Fe17Mn and Fe17Mn3Al) have been studied. It is observed that the application of thermo-mechanical processing (TMP) can significantly improve the low impact abrasion and low stress sliding wear resistance of both the steels. Thermo-mechanically processed Fe17Mn steel shows higher impact abrasion and sliding wear resistance compared to the thermo-mechanical...

Abstract Surface abrasive wear is a pathological manifestation that compromises concrete floors. Although the abrasion resistance of concretes has been extensively associated with the materials and matrix properties, the influence of the surface layer quality has been less explored. The present work investigated the influence of micro and macrostructural properties related to the surface layer as compared to matrix properties on the abrasion resistance of concretes with different materials and p...

Abstract Wear in sheet metal forming processes is influenced by numerous variables. Their impact has so far been investigated in model tests neglecting forming-specific tribological boundary conditions such as continuous infeed of new sheet metal material and lubricant as well as high local contact stresses. This paper proposes a new testing method which overcomes these deficits and allows for a high resolution of wear formation in time. Thus, the wear behavior of different tribological systems ...

Abstract A deep gradient wear-resistant layer is applied to 20CrMnTi gear steel with high hardness and thick case. The tribological properties of wear-resistant layers are studied with different relative rolling-sliding ratios. The results indicate that the overall wear resistance of the deep-gradient-layer sample is 1.8–6 times higher than that of the conventional heat treatment sample. The deep-gradient-layer sample is less sensitive to tangential force compared with the conventional heat trea...

Abstract The demand for high quality micro components has been on the upsurge for the past few decades. Nowadays micro end milling is preferred to produce 3D micro parts. This paper presents an investigation on wear behavior of solid tungsten carbide (WC) tool with TiAlN coating during micro end milling of Ti-6Al-4V. Miniaturization of the tool combined with machining of hard to machine material like Ti-6Al-4V results in rapid tool wear. Feed/tooth to tool edge radius ratio (f/r) has got signifi...

Abstract Corrosive wear is a form of material degradation that is known to occur on equipment and components that handle suspended solids in aqueous solutions. This surface deterioration process is generally enhanced when the fluids contain chlorides that are acidic in nature. Such environments are encountered in many applications, one such example being the minerals processing industry. High chromium white cast irons are widely used in many engineering applications as they extend the service li...
