Simulating strain requires experimental validation. In this work, a method for the non-destructive determination of plastic strain in an extruded tube profile is presented. A copper coating, which deforms with the billet material, was used in the developed non-destructive method and was detected by computed tomography (CT) to analyze the deformation. The pattern was applied on cast billet halves (in the longitudinal direction) by a plasma coating technology. It was thus possible to determine the deformation of the pattern during the extrusion process in the billet as well as in the final profile without disassembling the extruded parts. A comparison of specimen using two different patterns shows the superiority of the simpler pattern consisting of only cross markers. © 2016 Author(s).

The practicability of thin metallic coatings applied on glass substrates depends strongly on the adhesion strength properties. In the present research, the effects of surface modification on the adhesive properties of copper coatings were studied. The surface modification was performed by activation of glass substrate with a plasma energy source directly before coating deposition. The results were compared with the properties of a not-activated glass substrate. Different surface analyses such as confocal microscope, scanning electron microscope (SEM), combined with contact angle measurements were done to investigate the effects of plasma activation on float glass. Scratch tests and adhesion tensile tests were performed to evaluate the adhesive properties of the thin coatings. In order to perform the adhesion tests, adhesive film FM 1000 was used. The adhesive film is the only practical adhesive used for porous copper coatings sprayed on float glass. It was observed that surface modification by plasma treatment leads to a chemical reaction on the substrate surface and furthermore to an increased wettability of the glass substrate, whereas the surface roughness and the microstructure of the substrate does not change. Finally, the experiments showed an increase of the adhesion strength of the copper coatings. Copyright © 2015 Inderscience Enterprises Ltd.

The atmospheric plasma spray (APS) process for applying thin coatings on substrates has a lot of different process parameters. To evaluate which parameters have the most significant influence on the adhesive strength, a design of experience (DoE) investigation was performed. The data for the DoE analyses were generated with an own designed adhesive tensile strength test device according to EN 13144. For these experiments, the two component epoxy HTK Ultra Bond 100 was used for loading the interface of APS zinc coated steel samples. To provide a highly repeatable test setup, a special gluing device was developed to cope with the requirements of the Ultra Bond 100. Although the DoE analysis showed the expected results, the pull-off test has some weaknesses, which are shown and discussed in the present paper. © Carl Hanser Verlag München.
