Processing, Microstructure and Properties of Different Method Obtained Cu-Al2O3 Composites/ Wytwarzanie, Mikrostruktura I Właściwości Kompozytów Cu-Al2O3 Otrzymywanych Róznymi Technikami

Abstract: WYTWARZANIE, MIKROSTRUKTURA I WŁAŚCIWOŚCI KOMPOZYTÓW Cu-Al 2 O 3 OTRZYMYWANYCH RÓŻNYMI TECHNIKAMIAlumina/copper composites are used where high thermal conductivity, high absorption and dissipation of heat, high resistance to thermal fatigue and good frictional wear resistance are required. The properties of these composites depend on a number of factors including the content, shape and distribution of the ceramic phase, the method of their obtaining, as well as the conditions under which they are obtained.

“…Composites similar and similar thin hard coatings [2][3][4] belong to a constantly developing group of advanced materials, the properties of which are superior to those of conventional monolithic materials [5]. Through an appropriate choice of the components of a composite, one is able to effectively control their desired properties and increase functionality [6]. Various forms of carbon, in particular graphene, have generated a lot of interest due to their characteristics.…”

“…[8,9]. Some other ceramic phases like Al 2 O 3 , AlN, SiC or Si 3 N 4 added to copper matrix, especially in nanosized form, can be the competitors for them [10][11][12][13]. Using of ceramic reinforcement allow for the obtaining the coefficient of friction for composites equal as for pure copper, but simultaneously wear depth of copper matrix composites is less than that of Cu due to stable microstructure.…”

“…The literature of the subject is full of examples of materials with a high application potential, e.g. Cu-Mo, Cu-Be, Cu-C (diamond, CNT, graphene), Cu-SiC, Cu-AlN, Al-SiC, Al-AlN [2][3]. Copper with a thermal conductivity of about 400 W/mK is used whenever both high thermal and electric conductivities are required, but the application range of this material is limited because of its unsatisfactory mechanical properties, particularly at elevated temperatures.…”
