A Determination of the Influence of Technological Parameters on the Quality of the Created Layer in the Process of Cataphoretic Coating

Cataphoresis varnishing enables an organic coating to form on aluminum substrate, thus increasing its corrosion resistance and durability. is known ensure a high adhesion of the created cataphoresis layer good homogeneity this layer, even surfaces with complex geometry. This paper aimed optimize deposition process analyze evaluate thickness formed substrate from AW 1050—H24 material. In total, 30 separate samples were in accordance Design Experiments methodology, using central composite plan. The independent input factors study were: electrical voltage (U) time (tKTL) at polymerization times 15 min, 20 25 respectively. results statistical analysis showed that accounted for 33.82% change contributed 28.67% thi change. At same time, interaction (p < 0.0001) 20.25% under formation. regression model was constructed degree prediction accuracy (85.8775%) use as function nonlinear optimization provided maximum th max = 26.114 µm, U 240 V tKTL 6.0 proven experimental conditions.
