Microstructural and tribological properties of A356 Al-Si alloy reinforced with Al2O3 particles
(Springer/Plenum Publishers, New York, 2008)
In the present study, the effect of the Al2O3 particles (average size of 12 mu m, 3 and 10 wt.%) reinforcement on the microstructure and tribological properties of Al-Si alloy (A356) was investigated. Composites were ...
Structural, mechanical and tribological properties of A356 aluminium alloy reinforced with Al2O3, SiC and SiC plus graphite particles
(Elsevier Science Sa, Lausanne, 2010)
Particulate composites with A356 aluminium alloy as a matrix were produced by compocasting process using ceramic particles (Al2O3, SiC) and graphite particles. The matrix alloy and the composites were thermally processed ...
Continuous control as alternative route for wear monitoring by measuring penetration depth during linear reciprocating sliding of Ti6Al4V alloy
(Elsevier Science Sa, Lausanne, 2011)
Continuous wear monitoring during linear reciprocating sliding was investigated. Tribological tests with Ti6Al4V alloy against alumina, at nanotribometer, on microscale, were realised in dry conditions over a range of loads ...
Technological heredity - A decisive factor for tribological features of regenerated gears
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The reparatory hardfacing of damaged contact surfaces is the most reliable method of renewing the tooth shape, dimensions and operating characteristics of failed gears. Proper selection of method suitable for reparatory ...
Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
Structural, mechanical and tribological characterization of Zn25Al alloys with Si and Sr addition
(Elsevier Sci Ltd, Oxford, 2014)
The ZA-27 alloy is a zinc-aluminium casting alloy that has been frequently used as the material for sleeves of plain bearings. It has good physical, mechanical and tribological properties. However, one of the major ...
Crossed helical gears with wheels from sintered steel with pyrohydrolysis
(Trans Tech Publications Ltd, 2013)
Crossed helical gears are used in cars and in many household appliances. The trend towards increased comfort in motor vehicles has led to the utilization of more than a hundred servo-drives in luxury class automobiles. ...
Studying the load carrying capacity of spur gear tooth flanks
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The impact of load distribution in meshed teeth, teeth geometry and manufacturing accuracy on wear of the spur gear tooth flanks is studied in this paper. The original geometry of teeth is impaired wearing. Due to that, ...
Wear of internal combustion engine parts with possibilities for their regeneration
(Expert Verlag, 2014)
Only 12% of the total energy of the fuel finds its way to the driving wheels, while 15% of it is being dissipated as mechanical, mainly frictional losses. These numbers could be improved by applying methods of reparation ...
The effect of processing techniques on microstructural and tribological properties of copper-based alloys
(Elsevier Science Bv, Amsterdam, 2013)
Three copper-based alloys, i.e. two composites reinforced with Al2O3 particles and fabricated through PM route and Cu-Cr-Zr alloy processed by the vacuum melting and casting technique were the object of this investigation. ...
