Abstract: | In this work the method of response surfaces was used for the purpose of drawing up a mathematical model for the calculation
(forecasting) of the adhesion of a flame sprayed coating of powdered aluminum on S 235 JR steel. Experimental work was conducted
according to a fractional central-composite design at three levels. The adhesion of the coatings made with combinations of
input parameters of the procedure according to the experiment plan mentioned is measured in line with the EN 582 standard.
A mathematical model was derived describing the dependence of the experimentally obtained adhesion values on the input parameters
of the procedure. The possibility of analyzing the influence of the parameters on the adhesion for a certain combination of
input parameters has been presented with the use of perturbation plots. |
