Abstrakt: | The purpose of the preset study was to evaluate the influence of the pulsed anodising process parameters on the surface topography of anodic oxide coatings on the aluminium alloy EN-A W 5251. The pulsed anodising process was conducted using a rectangular current waveform of variable frequency (100-0,2 Hz) and a variable duty cycle of the pulse (100-40%). Measurement of the anodic oxide coating, A12O3, surface roughness (2D and 3D) was made using the Form Talysurf Series 2 profilographometer. Evaluation of the A12O3 coating morphology was made by image analysis, based on surface pictures acquired by means of a scanning electron microscope, Philips XL 30 ESEM/TMP. The research results prove that the application of the pulse method with a rectangular current waveform for the anodization of aluminium alloys allows a reduction of the amplitude parameters of surface roughness and a modification of anodic oxide coating porosity. |
