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 ...
A fuzzy model for an increase in locomotive traction force
(Vilnius Gediminas Tech Univ, Vilnius, 2010)
This paper deals with the process of traction force realization described by a suitable mechanical model and is pointed to the adhesion phenomenon as a physical one, i.e. is a suitable factor that the value of traction ...
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 ...
