Resistance of modified material surfaces for agricultural tillage tools to wear by soil particles
Metalurgija, 2022 Agricultural tillage tools are exposed to various forms of wear during operation. Abrasive wear by soil particles is the most important wear form, and the most exposed to it are representatives of tools whose working parts are in direct contact with the ...

The tribological and wear properties of carbon-graphite composites
, 1994 A range of carbon-graphites with differing properties has been evaluated for wear resistance. These include carbons with a high degree of graphitic order (natural and synthetic graphite), those with little or no such order (pitch bonded cokes, glassy ...

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 ...

Wear performance of quenched wear resistant steels in abrasive slurry erosion
, 2016 Three commercially available quenched wear resistant steel grades were compared with a structural steel and four elastomer materials to reveal the differences in their behavior in slurry erosion conditions and to find the best solutions for demanding ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels
Advanced Materials Interfaces, EarlyView.When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Abrasive machining with MQSL. [PDF]
, 2011 Grinding and polishing of engineered components are critical aspects of the precision manufacturing of high performance, quality assured products. Elevated process temperatures, however, are a common and for the most part undesirable feature of the ...

Advanced Materials Interfaces, EarlyView.Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...
