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 ...
Microwave sintering improves the mechanical properties of biphasic calcium phosphates from hydroxyapatite microspheres produced from hydrothermal processing
(Springer, New York, 2010)
Starting from two microspherical agglomerated HAP powders, porous biphasic HAP/TCP bioceramics were obtained by microwave sintering. During the sintering the HAP powders turned into biphasic mixtures, whereby HAP was the ...
Influence of internal radial clearance on the ball bearing service life
(Journal of the Balkan Tribological Association, 2010)
External load of ball bearing is transferred from one ring to other one through balls. In the radially loaded bearing all balls are not simultaneously active. Simultaneously active balls participating in load transfer are ...
