Abstract
In the present investigation, the influence of B4Cp particles on the mechanical and tribological behavior of Al 359 composites has been studied. B4Cp particle reinforced Al 359 composite samples were prepared by stir casting process. Hardness, tensile strength and wear behavior of the composites were studied and compared with a control specimen. Hardness of B4Cp particles reinforced Al 359 matrix increases compared to base matrix due to the presence of the ceramic phase. Coefficient of friction considerably increases with up to 20 wt.-% addition of B4Cp in base matrix. Specimens were subjected to wear tests under different load conditions and the following five different wear mechanisms such as wear groove, abrasion, delamination, oxidation and plastic deformation were evaluated. The abrasion results prove the increase in wear resistance of B4Cp reinforced composites compared to a control specimen.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde der Einfluss von B4Cp-Partikeln auf das mechanische und tribologische Verhalten von Al 359 Kompositen untersucht. Die mit B4Cp-Partikeln verstärkten Al 359 Kompositproben wurden mittels des Rührgießprozesses hergestellt. Die Härte, die Zugfestigkeit und das Verschleißverhalten der Komposite wurde untersucht und mit einer Kontrollprobe verglichen. Die Härte der mit B4Cp-Partikeln verstärkten Al 359 Matrix nimmt im Vergleich zur Basismatrix zu, und zwar aufgrund der Anwesenheit der keramischen Phase. Der Reibkoeffizient nimmt bemerkenswert zu, wenn bis zu 20 wt.-% B4Cp in der Basismatrix zugegeben werden. Die Proben wurden einem Verschleißversuch bei verschiedenen Belastungsbedingungen unterzogen und die fünf verschiedenen Verschleißmechanismen, wie Verschleißgrübchen, Abrieb, Delamination, Oxidation und plastische Verformung wurden evaluiert. Das Abriebergebnis zeigt, dass der Verschleißwiderstand der B4Cp-verstärkten Komposite im Vergleich zur Kontrollprobe zunahm.
