文摘

The structure and tribological behavior of composite materials (CMs) filed by dispersed particles and based on aluminum alloys grown by reactive casting with titanium microparticles and SiC nanoparticles or synthetic diamond mixed to the melt have been studied. The composition, size, and volume fraction of the strengthening phases are determined by optical microscopy and x-ray diffraction. The hardness of the CMs is measured. The tribological properties of the CMs are tested during dry friction on a rider made of grade 45 steel. Alloying nanoparticles are shown to affect the morphology, volume fraction, and sizes of the strengthening phases formed in the CMs. The main phases in the CMs are intermetallic compounds Al3Ti, Al24Ti9, and AlTi. The introduction of SiC nanoparticles in a CM causes the formation of TiSi2 (<1%) particles, whereas TiC carbides (<1%) form in a CM containing diamond nanoparticles. CM-steel friction interaction causes the formation of intermediate layers consisting of mechanical mixtures with an ultrafine-grained structure between the sliding surfaces. Their effect on the stable-friction range is discussed.
