Monotectic alloys can have interesting tribological characteristics with the solute acting as a solid lubricant, while the matrix provides required structural integrity. The addition of third elements can increase the alloy load capacity, and depending on the nature of the third element can also improve the tribological characteristics. The microstructural features of these alloys, such as morphology, distribution, length scale of the phases and consequently wear behavior depend strongly on the parameters of their manufacture route. In order to previously program the final properties of the metallic components produced by casting processes, it is important to develop a detailed study to establish correlations between microstructural as-cast features and tribological properties. Several alloys are currently identified with the potential application on tribological components but there is a lack in systematic studies involving microstructural growth under transient solidification regime and its correlations with wear resistance. The aim of the present project is contributing to a better understanding of this issues through the development of theoretical/experimental analysis in order to establish a correlation between representative parameters of solidification microstructures of Zn-Al-Bi monotectic alloys, thermal variables of transient solidification (growth and cooling rates) and dry wear resistance. The wear tests will be performed at the laboratories of the Centro Nacional de Investigaciones Metalurgicas (CENIM) from Madrid.
