3.1 Method of indicating powder brand
3.1.1 The Chinese phonetic letter "F" is used in front of the brand to indicate the powder. The brand itself consists of three parts. 3.1.2 The first part: Use Arabic numerals 1, 2, and 3 to indicate the base type. 1-Nickel base: 2-Cobalt base: 3-Iron base.
3.1.3 The second part: Use one Arabic numeral to indicate the spray-welding method. 1-Oxygen-acetylene flame spray welding: 2-Plasma spray welding. 3.1.4 The third part: Use two Arabic numerals to indicate the reference value of the hardness of the spray-welded layer. The second and third parts must be separated by a horizontal line. Example:
3.2 Brand
Reference value of hardness of spray welding layer

The chemical composition, particle size and hardness of the spray-welded layer of the alloy powder shall be inspected in accordance with the provisions of JB/T3168.2 and JB/T3168.3. 5.2 Inspection rules
5.2.1 Before leaving the factory, the powder must be inspected for chemical composition, weld layer hardness and particle size according to the batch number. The qualified batch shall not be less than 200kg5.2.2 When inspecting the powder, 5 samples shall be taken from different places of the same batch of powder, with a total weight of not less than 2kg, and then mixed evenly after merging, and then reduced to the required amount by the doubling method. When inspecting the chemical composition, it is recommended to use a powder sample with a particle size of 70~100μm. 5.2.3 If there are powders that do not meet the requirements of this standard after inspection, they should be re-inspected in double according to the above rules. After re-inspection, as long as one of the samples does not meet the requirements of this standard, the powder shall be judged as unqualified powder. 6 Packaging
Powders can be packaged in 1, 2, 5, and 10 kg weights. 6.1
The packaging must be sealed and moisture-proof to ensure that there is no leakage during transportation. 6.2
6.3 The following contents should be marked on the outer packaging box (bag): a) Name of goods:
b) Brand:
c) Batch number:
d) Net weight;
e) Particle size range;
D Packaging date:
g) Manufacturer's name.
