Thermal spraying - Spraying and fusing of self-fluxing alloys (ISO 14920:2015)

ISO 14920:2015 defines the procedure for thermal spraying of self-fluxing alloys that are simultaneously or subsequently fused to create a homogeneous, diffusion bonded coating.

Thermisches Spritzen - Spritzen und Einschmelzen von selbstfließenden Legierungen (ISO 14920:2015)

Diese Internationale Norm gilt für thermisches Spritzen von selbstfließenden Legierungen, die gleichzeitig oder anschließend eingeschmolzen werden, um eine homogene diffusionsgebundene Schicht zu schaffen.

Projection thermique - Projection et fusion d'alliages autofondants (ISO 14920:2015)

L'ISO 14920:2015 spécifie la méthode de projection thermique d'alliages autofondants, dont la fusion s'opère simultanément ou ultérieurement pour donner un revêtement homogène où les produits s'agglomèrent par diffusion.

Vroče brizganje (metalizacija) - Taljenje in brizganje - Vroče nanašanje samotaljivih zlitin (ISO 14920:2015)

Dokument zajema vroče brizganje samotaljivih zlitin, ki so spojene sočasno ali naknadno, da nastane homogen difuzijsko vezan premaz.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
