EN ISO 12679:2015 (E) 3DIN EN ISO 12679:2015-12 ForewordISO (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
36、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
37、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 Internati
38、onal 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 t
39、he subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 12679 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.EN ISO 12679:2015 (E) 4DIN EN ISO 12679:2015-12 IntroductionThermal spraying encompasses proces
40、ses 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 c
41、oating 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 hea
42、t 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 fro
43、m 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. T he workpieces to be coated are only slightly heated so that distortion and any other undesired st
44、ructural changes to the parent material are avoided. This does not apply if the coatings are thermally treated during or after the spraying process. T he application is not dependent on the size of the workpiece or component. The operation can be stationary or mobile depending on the spraying proces
45、s. E ven geometrically complex components can be coated using the appropriate spray set-up. T he untreated surface of spray coatings generally provides a good bond coat for painting. D epending on the spraying process and spray material, different coating thicknesses can be applied, although a coati
46、ng thickness of approximately 10 m is currently considered to be the lower limit.Process-related disadvantages are as follows: t he bond strength of thermally sprayed coatings without thermal post-treatment derives from adhesive forces only; t he bond strength can be influenced due to an expansion m
47、ismatch between the coating and substrate material, especially in the case of a high operation temperature; s pray coatings are micro-porous; t he thicker the spray coating, the higher the residual stresses in the coating, and the degree of multi-axial stress thus increases; s pray coatings without
48、additional thermal post-treatment are sensitive to edge pressure, localized and linear loads and to impact stresses; t here are restrictions in relation to the geometric dimensions, for example, for the inner coatings of workpieces whose inner diameter is too small.EN ISO 12679:2015 (E) 5DIN EN ISO
