Formability of Thin Steel Sheets Coated with Anodized Aluminum
Hušek, Martin ; Suchánek, Jan (referee) ; Spišák,, Emil (referee) ; Dvořák, Milan (advisor)
Thesis deals with the design of the technological process of anodic oxidation (creating elox coating) on aluminium film in the system steel-aluminium-elox, with the findings of characteristics of this system, comparing with the contemporary knowledge and practical utilization of this system in practice. My thesis in the teoretical part describes creating of anodic oxidation (elox coating) and the process of bending and stretching the sheet. Theoretical aspects of interaction among elox finish, process of bendings and process of stretching are implemented in the experimental part and they are supported by identified knowledge and results. The practical part is focused on improving adhesion, designing and constructing a multifunctional bending product for testing resistance of the finish applied on a tested product. Under the terms of determination distributing deformation and tension in bended coated plate, this plate is tested by statistic analysis with the help of the Finit Element Method (FEM) in the programme ANSYS. The experimental part compares discovered results of each experiment in the system steel – aluminium – elox with the results of aluminium plates with elox finish, stainless plates and steel plates with aluzinc.
