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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
Thermal spraying encompasses processes used in the production of coatings and free-standing bodies for which
spray materials are surface-melted, melted off or melted and then propelled onto suitably prepared workpiece
surfaces. The workpiece surfaces are not surface-melted. In order to achieve specific coating properties, the
spray coating can undergo additional post-treatment, either thermal or otherwise, for example, sealing.
Thermally sprayed coatings serve to improve the surface properties of a workpiece by manufacturing or repair
operations. This can be done, for example, in relation to wear, corrosion, heat transfer or heat insulation,
electrical conductivity or insulation, appearance and/or for restoring the part to working order. In certain cases,
a spray coating can render a surface solderable.
Chiefly due to their bonding mechanism, thermally sprayed coatings without thermal post-treatment can be
distinguished from coatings applied with other processes, such as deposition welding, brazing, physical vapour
deposition (PVD) or chemical vapour deposition (CVD).
The advantages of thermal spraying are the following.
— The workpieces to be coated are only slightly heated so that distortion and any other undesired structural
changes to the parent material are avoided. This does not apply if the coatings are thermally treated during
or after the spraying process.
— The application is not dependent on the size of the workpiece or component. The operation can be
stationary or mobile depending on the spraying process.
— Even geometrically complex components can be coated using the appropriate spray set-up.
— The untreated surface of spray coatings generally provides a good bond coat for painting.
— Depending on the spraying process and spray material, different coating thicknesses can be applied,
although a coating thickness of approximately 10 µm is currently considered to be the lo
