ISO 14917 pdf download.Thermal spraying — Terminology, classification 1 Scope This International Standard defines processes and general terms for thermal spraying. It classifies thermal spraying processes according to type of spray material, to type of operation and to type of energy carrier. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document listed below. For undated references, the latest editions of the normative documents referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 6507-1 :1 997, Metallic materials — Vickers hardness test — Part 1 : Test method. ISO 6507-2:1 997, Metallic materials — Vickers hardness test — Part 2: Verification of testing machines. ISO 6508:1 986 , Metallic materials — Hardness test — Rockwell test (scales A – B – C – D – E – F – G – H – K). ISO 1 491 6:1 999, Thermal spraying — Determination of tensile adhesive strength. 3 Term and definition For the purposes of this standard the following definition applies. 3.1 thermal spraying processes in which surfacing materials are heated to the plastic or molten state, inside or outside of the spraying gun/torch, and then propelled on to a prepared surface. The substrate remains unfused NOTE 1 Spray coatings can be applied by thermal spraying of material in its liquid or plastic pasty state. NOTE 2 To obtain specific properties of the deposit, a subsequent thermal, mechanical or sealing treatment may be used. 4 Process variations 4.1 Classification according to the type of spray material Distinction of the following variations: – wire spraying; – rod spraying; – cord spraying; – powder spraying; – molten bath spraying. 4.2 Classification according to the operation 4.2.1 Manual spraying All operations typical of the spraying process are manual. 4.2.2 Mechanized spraying All operations typical of the spraying process are mechanized. 4.2.3 Automatic spraying All operations typical of the spraying process are fully mechanized including all handling, e.g., workpiece loading and unloading, and are integrated in a programmed system. 4.3 Classification according to the energy carrier 4.3.1 Molten-bath spraying A surfacing material is heated to...
