5.1 Mechanical properties
The mechanical properties of the wires shall be suitable for trouble-free feeding and processing. If required, the mechanical properties should be specified among manufacturer, supplier and customer,
The temperofthermal spray wire should be suitable for uninterrupted feeding on thermal spray equipment.
NOTE Very hard, poorly tempered thermal spray wires are difficult to handle, hard to straighten, and cause excessive wear on vital gun parts such as drive rolls, guides and contact tubes or nozzles. On the other hand, too soft thermal spray wires (e.g. aluminium, tin, zinc) may cause problems with feeding.
5.2 Surface properties
The surface of the thermal spray wire shall be smooth and free of corrosion products, slivers and splits, shrinkholes, splices and scales, damages as well as neckings, welds and laps. Moreover, foreign matter that would adversely affect the thermal spray material’s characteristics or properties of the sprayed coating is to be avoided.
For arc spraying. martensitic and ferritic steel thermal spray wire shall be protected with a plating of copper to prevent corrosion during storage. The plating shall cover the whole wire surface without visible defects.
For alloys number 5.7 (Table 7) two variants are available: 5.7a) with copper plating and 5.7b) with another suitable plating. This condition is also valid for 5.16a) and 5.16b). A very small amount of lubricant that vill not degrade the sprayed coating may be applied to the thermal spray wire to permit smooth and low-friction feeding through the thermal spray equipment.
Using cored wires manufactured according to Clausei Table 1. should not be lubricated or treated by any liquids.
The surface of cords shall be smooth and free of neckings. The surface of rods shall be free of neckings and without scratches. Rods shall not exhibit end kinks or end-to-end warpage that could adversely affect rod feed.
5.3 Workability: Winding of wires
Wires shall be wound onto rims, coils and spools or inserted into barrels in one length. Kinks and sharp bends shall be avoided. The end shall be fastened to prevent unwinding. The beginning of the wire shall be marked so that It can be located readily. The outermost layer on spools shall be at least 3 mm from the rim of the flanges of the spool. The diameter of an unwound single wire coil shall not exceed 120% of the spool’s outer diameter but shall not be smaller than the spool’s inner diameter. The wire shall not contain a twist. An unwound winding shall remain flat when laying on the ground. Given careful handling, the coils shall unwind without problems.
The designation shall follow the principle given in the example below.
The designation of a thermal spray material made of an iron alloy containing 19 % Cr and 9 % Ni according to Tabk.Z code number 5.10, and a diameter of 1.6 mm, metallurgically manufactured and formed (see Table 1, code number 1) is:

7 Technical supply conditions
7.1 Forms of delivery
The products shall be delivered on rims, coils, spools or drums, see Table 14. Rods are delivered in packages of 25 or 100 pieces.ISO 14919-2015 pdf free download.
