Sažetak
The aim of this study was to acquire a three-dimensional qualitative and quantitative nano-scale data of surface topology of electropolished CoCr dental alloy, actually of the two different solid solutions previously described as dendrites and interdendritic regions.
Material and Methods: Ten CoCr alloy samples (Wironit® extra-hard, Bego, Germany) were prepared, cast and electropolished. The surface of the samples was recorded and analysed by atomic force microscopy (AFM), as well as with optical microscope. The AFM imaging and analysis made it possible to observe a surface of the CoCr dental alloy three-dimensionally. It has been understood that the dendritic surface structure of the CoCr alloy consists of clusters of nanocrystallites forming islands (corresponding the dark interdendritic regions on optical micrographs), which emerge from a smooth undulating surface (corresponding the light dendritic regions on optical micrographs).
Results: The 95% confidence interval (p<0.05) for the maximum z-value was from 819,98 to 1020,99 nm, for RMS values from 66,93 to 108,54 nm and for Ra (mean roughness) values from 51,53 to 82,48 nm.
Conclusion: The surface revealed favourable characteristics regarding
roughness, moreover the surface of the alloy can be considered really “smooth”, without any mechanical retentive features for microorganisms’ trapping.
