25、enticed qualified on theoretical knowledge according to EN ISO 14918 or adequate experience; 4) non destructive testing personnel qualification, if applicable: according to EN 473 class 2 for penetrant test (PT); 5) spraying equipment: checked according to the relevant part of EN 1395 or qualified b
26、y a correct function of the spraying equipment by test reports or coating results. 4.1.3 Preparing the instructions for thermal spraying (spray procedure specification) The manufacturer is responsible for preparing and ensuring the execution of instructions (see also EN ISO 14922). The spray procedu
27、re specification has to refer to the coating specification and the manufacturing instruction documents, like parts list, material instructions of parent metal and spraying material, drawings and test instructions. The spray procedure specification should be prepared in written form; only in case of
28、subordinate applications will a verbal form be accepted. If required, the spray procedure specification may be qualified by a component related spray procedure qualification. 4.2 Technical requirements 4.2.1 Spraying materials Only spraying materials which are indicated in the spray procedure specif
29、ication shall be applied. Preferably, the spraying material should comply with the technical supply conditions of EN 1274 for spraying powders and EN ISO 14919 for spraying wires, rods and cords. The conformity of the spraying material with the instructions in the spray procedure specification shoul
30、d be verified by comparison with the relevant test certificate from the manufacturer/supplier of the spraying material. The manufacturer/supplier processing instructions shall be considered. All spraying materials shall be stored in suitable packages. Marked spraying materials shall be used only. EN
31、 14616 gives instructions for supply and storage of spraying material. 4.2.2 Spray procedure specification The spray procedure specification shall contain all parameters which are necessary for the spraying procedure. The required parameters are to be determined by spraying tests or to be taken from
32、 adequate prior knowledge. The preparation of the substrates surface shall be specified in the spray procedure specification. Further instructions may be taken from EN 13507. Post treatments like machining, sealing the coating or heat treatment shall be specified in the spray procedure specification
33、 or in the operation sequence plan (see EN ISO 14924). If required, a test shall prove that the sprayed coating and/or the component will not be impaired by the post treatment process. When fusing self-fluxing alloys EN ISO 14920 contains further instructions. Licensed Copy: Wang Bin, na, Thu Sep 13

A review of or a new preparation
35、of the spraying procedure specification may be required. 4.2.3 Requirements for acceptance criteria for thermally sprayed coatings Requirements for acceptance criteria shall be specified in the coating specification, e.g. maximum and/or minimum values of hardness, tensile adhesive strength, coating
36、thickness, coating structure, porosity, roughness, grit residues at the interface, non-melted particles, time limit between surface preparation and spraying etc. If applicable, master pictures for bend and cupping tests, or test procedures for wear, corrosion or thermal cycling tests may be agreed u
37、pon between contracting parties. Where acceptance criteria and admissible imperfections are not specified in the coating specification or in the manufacturing instructions they shall be agreed between the contracting parties. In case of corrosion protection applications by zinc or aluminium EN ISO 2
38、063 shall apply for testing and acceptance criteria. 5 Quality tests 5.1 General Tests and their scope shall be contained in the coating specification and the spray procedure specification. Test instructions are to be prepared by the coating manufacturer in agreement with the customer, if required.
39、Where quality tests are not specified in the coating specification or agreed between contracting parties,tests and their scope shall be applied according to this European Standard. 5.2 Tests, scope of tests and requirement for accompanying test specimens Where mass or series production of coated com
40、ponents is carried out and when using tests indicated in Table 1 the actual number of components in a lot has to be considered. Accompanying test pieces for certain tests are shown in Table 2. Where a single, component is to be sprayed the percentage of a random test shall be calculated according to
41、 the size of the coated area. The influence of process stability (completely mechanised, manual, or process controlled in closed loop form) shall be considered when calculating random tests.
