30、d 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-treatm

31、ent, 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

32、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,

33、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 structural changes to the parent material a

34、re 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 process. E ven geometrically complex components

35、 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 coating thickness of approximately 10 m is cur

36、rently 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 mismatch between the coating and substrate

37、 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 additional thermal post-treatment are sen

38、sitive 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.ISO 12679:2011(E) ISO 2011 All rights reserved vBS EN ISO 12679:2015ISO 126
