Adhesive tensile testing of atmospheric plasma sprayed zinc coating on a 1.4301 substrate

Abstract
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.
Kurzfassung
Der Atmosphärenplasmaspritzprozess (APS) zum Auftragen dünner Schichten wird von einer Vielzahl an Prozessparameter beeinflusst. Um jene Parameter herauszufinden, welche einen signifikanten Einfluss auf die Schichthaftung haben, wurde eine Versuchsplan-Analyse (Design of Experiments (DoE-Analyse)) durchgeführt. Zur Generierung der Daten für die DoE-Analyse wurde, in Anlehnung an die Norm EN 13144, eine Abzugsvorrichtung entwickelt, um einen Stirnabzugsversuch durchführen zu können. Für die Verbindung zwischen beschichteten Substraten und Abzugsstempel wurde ein normgerechter Zweikomponenten Epoxidklebstoff namens HTK Ultra Bond 100 verwendet. Um eine reproduzierbare Klebung zu gewährleisten und den Anforderungen des Ultra Bond gerecht zu werden, wurde eine Verklebevorrichtung entwickelt. Obwohl die DoE-Analyse die erwarteten Ergebnisse zeigte, wurden bei der Versuchsdurchführung einige Schwächen des Stirnabzugsversuches festgestellt, welche in dieser Publikation aufgezeigt und diskutiert werden.
