Methods of Geometric Surface Structure Measurement of AW-2017A Alloy after Cavitation Wear

Jasionowski R., Zarański Z.

Archives of Foundry Engineering

Vol. 14, iss. 1 spec.

Evaluation of the cavitation erosion resistance of structural materials is based on selected measurement method. Destruction of the sample surface caused by cavitation phenomenon can be evaluated in laboratory conditions by measuring few quantitative parameters e.g. loss of mass of sample, quantity or weight of detached particles, the area of the worn material, the average and the maximum depth of cavitation erosion, the change of surface roughness or the number of cavities on the surface. In this paper optical and profilometry methods of geometric surface structure measurement of AW-2017A alloy after cavitation wear, were presented and compared. The optical method was carried out on Nikon Eclipse MA200 light microscope and profilometry method was performed using TOPO 01P v3D profilometer.

The investigations concern the roller burnishing process of PA10 aluminum alloy specimens.

Influence of metal surface structure on the anisotropic XPS

The intensive distribution of photoelectrons as a function of X-ray beam with variable angle of incidence was investigated. Diffraction caused by the structure of surface was observed in the following metal samples: Al with face-centered cube, Ta and W with body-centered cubes. No effect was observed in Fe and Cu samples. The effect is closely related to the anode high voltages and X-ray energy. There was a range of threshold values in which the surface structure effects could be defined in experimental high voltages of anode. The possible mechanism of this effect was discussed.
