This standard specifies the chemical composition and physical properties of powders commonly used in the production of thermal spray coatings.

GB/T19356—2003
This standard adopts ISO14232:2000\Composition and technical conditions for supply of thermal spray powders” (English version). This standard redrafts ISO14232. According to the basic situation of thermal spray powder technology in my country, this standard makes the following modifications to ISO14232:
…——Cancel the prefix and prefix of the international standard:——Use “this standard” instead of “this international standard”——Quote the Chinese standard of the equivalent international standard: The latest version of ISO3310-1 is ISO3310-1:2000. Since my country has not yet converted it into a national standard, this standard still quotes this international standard.
GB/T1479.1—1984 covers the Scott volumetric method + GB/T1479.11984 replaces IS03923-2:1981 which specifies the Scott volumetric method and is used in this standard. This standard replaces GB/T12608—1990 "Method for naming materials for thermal spray coatings". This standard is proposed by the China Machinery Industry Federation and is under the jurisdiction of the National Technical Committee for Standardization of Metallic and Non-metallic Coatings. The drafting units of this standard are: Wuhan Institute of Material Protection, Weishen Thermal Spraying Material Research Institute, Chengdu Zhenxing Jinjie Powder Factory. The main drafters of this standard are: Cao Qing, Kuang Yimu, Gan Chunhua, Wu Zijian, Yan. 1

3.1 Samples and sampling
Samples and sampling should be mixtures of uniform particle size. The corresponding sampling and sampling operation methods and equipment guidelines should comply with GB/T5314.
3.2 Chemical composition
The chemical composition can be determined by any appropriate test method, such as atomic absorption spectroscopy, flame emission spectroscopy, X-ray fluorescence analysis, chemical analysis, etc.
3.3 Particle size range
The typical particle size range applies to thermal spray powder feeding devices. When the particle size distribution is determined by the particle size measurement method in accordance with IS03310-1, the variation range of fine screening shall not exceed 2% and the variation range of coarse screening shall not exceed 5%. The apparent particle size depends on the measurement base technology, so the maximum permissible tolerance of the upper and lower particle size limits also depends on the measurement method. The measurement method, particle size range, and the maximum permissible tolerance of the upper and lower particle size limits should be agreed upon by the powder manufacturer and the thermal spray coating manufacturer to ensure the reproducibility of the thermal spray process.
The supplied powder should be suitable for thermal spraying process. The typical particle size range (in μm) available for thermal spraying process is as follows: -22/5;
-90/45
-45/5;
-63/16;
3.4 ​​Particle size distribution
In order to accurately express the particle size range, the particle size and its distribution must be measured. X-ray absorption method and laser beam scattering method are preferred because their reproducibility, rapidity and resolution are higher than traditional screening methods. The results of the determination of particle size and particle size distribution depend on the method used, and the powder is also affected by the solubility of the binder. Therefore, it must be published (150 3310-1: Revision of 1990). 1
GB/T 193562003
It is necessary to prove that the powder to be tested is suitable for the selected method. In addition to stating the results of the particle size distribution determination, the powder test certificate shall also state the test method used.
3.5 Manufacturing process - particle morphology
The powder production process shall be indicated, such as melting method, bonding method, agglomeration method, atomization method, etc. Scanning electron microscope and surface microscope can be used to show the particle shape and surface morphology, and the image can be compared with the sample provided by the manufacturer to determine the degree of similarity. Examples of the relationship between manufacturing process and particle morphology are shown in Appendix A. 3.6 Bulk density
The bulk density of the powder shall be determined in accordance with the provisions of GB/T1479 and expressed in g/cm2. 3.7 Flowability
The flowability of the powder shall be determined in accordance with the provisions of GB/T1482 and expressed in /50. 3.8 Microstructure
The microstructure can be determined by preparing metallographic specimens of cross-sections of the powder particles. Since the sample preparation method is critical, it should be agreed upon by the manufacturer and the user.
3.9 Determination of Phases
The type, amount, shape, structure, composition and size of the phases in multiphase powders can be determined by X-ray diffraction analysis, microprobe or metallography and quantitative image analysis.
