Abrasive and erosive wear of technical materials
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011 Operating reliability of agricultural, transport and construction machines is in a considerable degree influenced by corrosion and wear. These sorts of damage significantly influence the costs for the restoration of mechanical components, as well as ...

A comparison of bearing life in new and refurbished railway axle boxes [PDF]
, 2001 A simple linear dynamical model shows that at normal running speeds of freight wagons, forced oscillations due to periodic track compliance are transferred to the overlying unsprung mass and significantly amplified. Due to these oscillations, a small gap

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants
Advanced Healthcare Materials, EarlyView.We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.
