Abstract: Pt–Mo coated system annealed at 1050 C for 24 h was investigated using several analytical techniques with high resolution (SEM/EDX, l-PIXE, RBS and XRD). These techniques provide structural and compositional data throughout the material depth and probing area. The results depend on the applied beam, its energy and size. They contribute to a better understanding of thermal annealing effects on the solid-state phase transformation and morphological changes in Pt–Mo coatings. The results indicate the presence of Pt- and Mo-solid solutions and two Pt–Mo phases (PtMo and Pt2Mo3), changes in the coating morphology, such as increased surface roughness and formation of ‘‘lace morphology’’, as well as an increase in coating thickness.
