THE APPLICATION OF MATHEMATICAL AND STATISTICAL METHODS IN TECHNICAL PRACTICE

摘要

The paper deals with the application of mathematical and statistical methods to identify and analyse factors acting during the process of aluminium anodic oxidation at defined current density of 1 Adm~(-2). The influence of input chemical and physical factors and their interactions on the resulting layer thickness has been investigated in order to determine the theoretical speed of layer creation. Based on the Design of Experiments methodology the set of 26 experimental runs was carried out, data were analysed and prediction model was developed.
