AFM ANALYSIS OF ALUMINIUM ALLOY 7075

In this paper we present the results of atomic force microscopy (AFM) characterization of the surface morphology new type of composite based on the high-tensile aluminium alloy 7075 strengthened with nanoparticles of diamond powder and tungsten is developed, stored for 28 months under different conditions. One sample was stored on Earth at room temperature and second one was mounted on the outer side of the International Space Station.
