Thermal spraying - Pre-treatment of surfaces of metallic parts and components for thermal spraying
The surface preparation of a work part may have a substantial effect on the performance of sprayed coatings especially with regard to their adhesion to the substrate and thus their protective action. In this standard, important principles are defined which must be taken into consideration when surfaces of metallic parts are prepared for thermal spraying. They are valid for new production as well as for the repair of worn parts.
Thermisches Spritzen - Vorbehandlung von Oberflächen metallischer Werkstücke und Bauteile für das thermische Spritzen
1 Anwendungsbereich
Die Oberflächenvorbereitung eines Bauteils kann einen wesentlichen Einfluss auf die Güte einer Spritzschicht haben. Dies gilt besonders bezüglich ihrer Haftung zum Grundwerkstoff und damit ihrer Schutzfunktion. In dieser Norm werden die besonderen Grundsätze festgelegt, die bei der Vorbereitung von Oberflächen metallischer Werkstücke zum thermischen Spritzen beachtet werden müssen. Sie gelten sowohl für die Neufertigung als auch für das Instandset-zen. Diese europäische Norm gibt Hinweise zu den notwendigen Verfahren und Werkstoffen, die über die in EN 22063 gegebenen hinausgehen.
Projection thermique - Traitement préalable de surfaces de pieces et composants métalliques pour projection thermique
Domaine d'application
La préparation des surfaces métalliques peut avoir un effet significatif sur les performances des couches projetées, notamment en ce qui concerne leur adhérence au matériau de base et, par conséquent, leur action de protection. La présente norme internationale décrit les principes de base a prendre en compte lors de la préparation des surfaces métalliques destinées a recevoir une protection par projection thermique. Ces principes valent tant pour une nouvelle production que pour la réparation de parties usées. La présente norme Européenne fournit des informations qui concernent les méthodes et produits nécessaires et completent celles données dans l'ISO 22063.

3 Principles
In order to provide satisfactory adhesion of sprayed coating to the substrate, the surface shall be properly prepared
1
and the subsequent spraying carried out with a minimum of delay ).
The metallic surface shall be processed until a technically clean interface is generated. Welding splashes and
residues of welding slag shall be removed, and welding seams and brazed or soldered joints must be prepared with
particular accuracy. Oxides, oil, grease and similar contamination shall be removed. The roughness of the surface
shall enable a good mechanical locking of the sprayed coating to the substrate. Grit blasting is a suitable method
for obtaining appropriate roughened and activated metallic surfaces, thereby also enlarging the effective area.
The surfaces shall be kept dry during the preparation and spraying process. For outdoor spraying this requirement
shall be met by taking suitable precautions.
4 Methods of surface preparation
Depending upon the function of the sprayed coatings and the initial condition of the surface different preparation
procedures are used. In all cases scale, rust, dust, and other contaminants shall be removed by mechanical
cleaning.
4.1 Degreasing
Oil and grease contaminants shall be removed thoroughly prior to processing the surface. In particular attention shall
