“…Belmonte et al [7] found that the wear resis- (11) tance of Al 2 O 3 /20 vol.% SiC composites increased with the SiC grain size (ranging from 0.2 to 4.5 µm) due to the enhancement of the fracture toughness. Fu et al [19] showed that Sal/SiC/Al hybrid MMCs presented the best wear properties in comparison with Sal/Al, Sal/Al 2 O 3 /Al, and Sal/SiC/Al hybrid MMCs under dry sliding wear conditions.…”

Al2O3/SiC particulate reinforced metal matrix composites were produced by a stir casting process. The Al2O3/SiC powder mix was prepared by reaction of aqueous solution of aluminium sulphate, ammonium sulphate and water containing SiC particles at 1200• C. 10 wt% of this hybrid ceramic powder with dierent sized SiC particles was added to a liquid matrix alloy during a mechanical stirring between solidus and liquidus under inert conditions. Dry sliding wear tests were conducted with a pin-on-disk friction and wear tester. The morphologies of the worn surfaces were examined using a scanning electron microscope to observe the wear characteristics and investigate the wear mechanism. An optical microscope was used to examine the precipitations of the hybrid ceramic reinforced metal matrix composites after wear tests at room temperature under dry conditions. It was found that hybrid and bimodal particle reinforcement decreased weight loss especially when SiC powder with larger grain size was used. Microstructural examination showed that besides occurring coarse SiC particle reinforcement, a ne alumina particle reinforcement phase was observed within the aluminium matrix (A332). The improvement in wear resistance of the hybrid ceramic reinforced metal matrix composites could be attributed to the ability of the larger SiC particles to carry a greater portion of the applied load, as well as to the function of the larger SiC particles in protecting the smaller alumina particles from being gouged out during the wear process. Furthermore, the incorporation of hybrid and bimodal particles increased hardness of the composites with respect to the composite with fully small sized particles.

“…Research on the effect of the grain size of secondary phases in ceramic composites on their wear behaviour has been reported before [16,17]. However, information on the sliding friction and wear behaviour of zirconia-based composites is relatively scarce [18].…”

Sliding Wear of Electrically Conductive ZrO2−WC Composites Against WC–Co Cemented Carbide

ZrO 2 -based composites with WC addition can be successfully machined by electrical discharge machining (EDM) in demineralised water. ZrO 2 composites with 40 vol.% WC were produced from nanocrystalline and micrometre sized WC starting powders in order to compare their tribological behaviour. Friction and wear data are obtained on wire-EDM'ed ZrO 2 -WC composite flats sliding against a WC-Co cemented carbide pin using a smallscale pin-on-plate testing rig. Correlations between wear volume, wear rate and friction coefficient on the one hand and material properties and test conditions on the other hand were elucidated. The experimental results revealed that the grain size of the electro-conductive WC-phase exhibits a strong influence on the friction and wear behaviour of the ZrO 2 -based composite.

“…To meet the need of the severe cutting conditions and the durable tool-life in high speed cutting process, ceramic tool materials should have good mechanical properties, such as high hardness, high flexural strength, high fracture toughness, good wear resistance and elevated-temperature anti-oxidation. In order to improve the mechanical properties further, the second-phase powders are combined on the base of matrix powder to develop the composite ceramic tool materials by hot-press fabrication (Lang, 1982;, Mukhopadhyay et al, 2007Belmonte et al, 2006).…”
