Abstract
The development of new materials that may contribute to the improvement of tribological systems such as reduced friction and decreased wear has been of interest to researchers worldwide. The use of PTFE as a high performance thermoplastic has already been established in the market due to its excellent surface characteristics, low coefficient of friction, and high lubrificity, associated to the high performance under impact. Among the disadvantages in the use of this material is the low wear resistance as well as limited mechanical resistance. The objective of this work was the development of PTFE composite with powder loading of quasicrystalline alloys in order to obtain a material with excellent surface characteristics, due to the characteristics of the matrix as well as the metallic powder, associated with high wear resistance and mechanical properties. quasicrystalline reinforcement. The composites showed good density after sintering Besides low porosity, so the viability in the development of composite PTFE/QC, with better mechanical performance characteristics//surface when compared to precursors and pure PTFE elements.
