Thermal spraying—Wires,rods and cords for flame and arc spraying—Classification and technical supply condition
Some standard content:
GB/T12608--2003
This standard is modified to adopt the English version of ISO14919:2001 "Wires for thermal spraying flame and arc spraying. Classification and supply technical conditions for powders and core materials".
According to my country's national conditions, the part of TS014919:2001 that quotes the European standard EV10204:1991 "Types of inspection documents for metal products" is modified to quote the national standard GB/T14436-1993 "General Principles of Industrial Product Assurance Documents": core materials with a diameter of 2.0 mm are added. The foreword of the international standard is deleted. This standard and GB/T19356-2003 "Thermal spraying powder: 2 Classification and supply technical conditions" replace GB/T12608-990 "Nomenclature of thermal spraying materials". Compared with GB/112608-1990, this standard has the following changes: 1. The material classification method has been changed, and the classification method of international standards has been fully adopted; 2. The material marking method has been changed, and the marking method of international standards has been fully adopted; 3. The content of Chapter 4 "Material Classification and Nomenclature Preparation and Management" in the original standard has been deleted; 4. The technical conditions for material supply have been added, and some technical conditions common to various materials have been specified. This standard is managed by the China Machinery Industry Federation. This standard is under the jurisdiction of the Technical Committee for Standardization of Metallic and Non-metallic Coatings. The drafting units of this standard are Wuhan Institute of Material Protection and Shanghai Ruifa Spraying Machinery Co., Ltd. The main drafters of this standard are Jiang Hongsheng, Chen Huiguo, Zuo Danjiang, Liu Zishan, 1 Scope

4 Dimensions and tolerances
GB/T12608—2003
The standard dimensions and tolerances of the diameters of wires, slugs and core materials for thermal spraying are shown in Tables 11, 12 and 13. If necessary, the user can negotiate with the manufacturer or supplier to determine a smaller tolerance range. The straightness of the material must be good so that the material will not break when it is fed. Wire diameter

The mechanical properties of the wire should be such that there are no problems with the wire during feeding and spraying. If necessary, the mechanical properties of the wire should be agreed upon by the manufacturer, supplier and user.
Note that the tempering treatment of the hot spray wire should be such that the wire is suitable for continuous feeding on the hot spray equipment. Inadequately tempered, too hard thermal spray wire is difficult to handle, difficult to straighten, and can cause important parts of the spray gun, such as feeding wheels, guides, conductive tubes or excessive spraying to wear out. On the other hand, too soft thermal spray wire (such as lead, pot, zinc, etc.) can cause feeding difficulties. 5.2 Surface properties
The surface of the thermal spray wire must be smooth and free from corrosion products, burrs and cracks, shrinkage cavities, overlaps and scales, as well as defects such as necking, welds and curling. In addition, foreign matter that affects the properties of the thermal spray material or the properties of the thermal spray coating should be removed. Martensitic and ferritic steel wires used for arc spraying should be bonded to prevent corrosion during storage. The coating should cover all surfaces of the wire without obvious defects.
Alloy wires numbered 5.7 (see Table 7) are of two types: 5.7a) are wires with copper coatings, and 5.7h) are wires with other suitable coatings. Without degrading the spray coating, a very small amount of lubricant may be applied to such thermal spray wires to allow the wires to be smoothly and low-frictioned through the thermal spray equipment. Note that cored wires manufactured according to the method in Table 1 of Chapter 3 cannot be lubricated or treated with any other agent. The core surface must be smooth and free of necking. The rod surface must be free of necking and scratching. The head of the rod should be free of twisting and head-to-head warping, which will affect the feeding of the rod. GB/T12608—2003 5.3 Workability: Wire winding Wires should be wound in wires, on reels, or in coils or in barrels. Twists or sharp bends should be avoided. The head of the wire should be tied tightly to prevent unraveling. The beginning of the wire should be marked for easy retrieval. The outermost layer of the wire on the spool should be at least 3 Ⅱm away from the reverse edge of the spool flange. The diameter of any loose single wire should not be greater than 1.2 times the outer diameter of the spool, and should not be less than the inner diameter of the spool. The wire should not be twisted. The loose and bottomed velvet rolls should be kept flat on the runner. The unwinding of the wire rolls does not affect normal use. 6 Sampling and testing
Any test of thermal spraying materials should be sampled at the beginning of the thermal spraying material packaging. In order to evaluate a thermal spraying material, a spraying performance test can be arranged between the supplier and the user. All types of analytical methods are applicable to the determination of the composition of thermal spraying materials, only within their proven test range: 7 Marking
Marking should be carried out according to the principles given in the following example.
The ferroalloy thermal spraying material containing 18%Ct, 85Ni, 6%Mn and 0.15%C, with a diameter of 1.6mm and manufactured and formed by metallurgical method (see Table 1. No. 1) and conforming to No. 5.10 in Table 7 is marked as: Thermal spraying material GB/T12608-5.[0-1,6-18 Technical requirements for supply
8.1 Form of supply
The material is supplied in the form of wire drum, wire coil, wire spool or barrel. The size is shown in Table 14. The material is supplied in bundles of 50 or 100. 8.2 Labeling
Wire in spools, baskets, reels, coils and drums and each package of ceramic rods shall have a durable label providing the following information:
Marking required by Section 7
- Name and trademark of the manufacturer/supplier # Label number:
- Net weight:
... Spools and baskets shall have a label containing the above information securely affixed to the inside surface of the spool or to a conspicuous location on the outside of at least one flange:
A reel shall have a label containing the above information securely affixed to the inside surface of the reel A coil shall have a label containing the above information securely affixed to a conspicuous location on the package Drums shall have a label containing the above information securely affixed to a conspicuous location on the top, and the side of the drum shall also have a label; - Ceramic rods shall have a label containing the above information securely affixed to a conspicuous location on the outside of the package: If the thermal spray material has an outer package, the above information shall also be marked on the outer package. 8.3 Packaging and storage
If there is no other cooperation, the thermal spray materials are supplied in packaging, which is to protect the materials from damage, contamination and corrosion. Ceramic rods should be packaged in impact-resistant tubular containers to prevent damage during transportation. Packaged thermal spray materials should be stored in a dry room at room temperature. 9 Certificates
9.1 Product Quality Assurance
A product quality assurance certificate that meets the requirements of 4.2 of GB/T14436-1993 is provided with the thermal spray materials. 10
9.2 Product Certificate
GB/T1260B-2003
If there is an agreement between the user and the supplier/manufacturer, a product certificate that meets the requirements of 4 of GB/T14436-1993 should also be provided.
According to the agreement between the customer and the supplier/manufacturer, in addition to the chemical analysis and mechanical performance test results, the product certificate should also indicate the supplier's product mark and batch number.
