EN ISO 14921:2001

Thermal spraying - Procedures for the application of thermally sprayed coatings for engineering components (ISO 14921:2001)

This standard relates to the general procedures of application of thermally sprayed coatings as defined in EN 657.
The purpose of these coatings being either to reclaim worn and non conforming parts or to enhance the surface
properties of components for specific purposes.
For example, to provide wear resistance, low coefficient of friction, electrical  or thermal conductivity or insulation,
and resistance to corrosion.
This standard is not intended to provide definitive methods for specific work  and attention shall be paid to the proper
selection of process and materials for the purpose and to the skills of the thermal sprayer as defined in
EN ISO 14918.
Additionally it does not include requirements for the protection of structural steelwork, covered by EN 22063, nor the
use of coatings of self fluxing  alloys which are subsequently fused, covered by EN ISO 14920.

Thermisches Spritzen - Vorgehen für das Anwenden thermischer Spritzschichten für Bauteile im Maschinenbau (ISO 14921:2001)

Diese Norm bezieht sich auf die in EN 657 definierten Verfahren zum Aufbringen thermischer Spritzschichten. Diese Schichten dienen entweder der Reparatur verschlissener und nicht passender Teile oder der Verbesserung der Oberflächeneigenschaften von Bauteilen für bestimmte Zwecke. Zum Beispiel können dadurch Verschleißbeständigkeit, Verringerung des Reibungskoeffizienten, der elektrischen oder thermischen Leitfähigkeit oder Isolation sowie Korrosionsbeständigkeit erzielt werden.

Projection thermique - Procédure d'application de revêtements obtenus par projection thermique pour les pièces mécaniques (ISO 14921:2001)

L'ISO 14921 traite des méthodes générales d'application des couches projetées thermiquement telles que définies dans l'EN 657. Ces revêtements permettent soit de récupérer des pièces usées et non conformes, soit d'améliorer les propriétés de la surface de pièces destinées à des applications spécifiques.
Sont, par exemple, concernées les caractéristiques suivantes: résistance à l'usure, faible coefficient de frottement, isolation ou conductivité électrique ou thermique, et résistance à la corrosion.
L'ISO 14921 ne vise pas à fournir des méthodes reconnues pour une pièce à traiter spécifique et il faut veiller d'une part, à choisir convenablement le procédé et les matériaux en fonction de l'application voulue, et d'autre part, à faire appel aux personnels ayant les compétences nécessaires en matière de projection thermique, telles que définies dans l'EN ISO 14918.
Elle ne comprend pas aucune exigence sur la protection des structures en acier qui relèvent de l'EN 22063 ou sur l'utilisation des revêtements en alliages auto-fondants qui sont fondus à une étape ultérieure, relevant de l'EN ISO 14920.
