[0019] Example 1
[0020] The brazing alloy is made of BAg40CuZnCdNi (national standard brand HL312, calculated by mass fraction percentage, Ag-Cu16-Zn18-Cd26-Ni0.2) with a thickness of 0.2mm. The hard alloy particles are cast and carbonized with 20-30 mesh. Tungsten powder, flux choose FB102, the ratio of flux to cemented carbide particles is 1:10 calculated by weight, after powder feeding (mixture of cemented carbide particles and flux), drawing, straightening, etc. To form a tubular brazing material with a diameter of 3mm and a length of 400mm, the brazing alloy coating layer 1 accounts for 11% of the total weight of the tubular brazing material, and the mixture of cast tungsten carbide powder and flux 2 accounts for the total weight of the tubular brazing material 89%. Q235 carbon steel is selected as the base material, and the product of this embodiment is subjected to an abrasive wear test. The abrasive wear test is performed on the MLG-130A dry rubber wheel abrasive wear...

[0021] Example 2
[0022] BCu58ZnMn (National Standard HL105, Cu58-Zn38-Mn4) solder alloy strip with a thickness of 0.2mm is selected for the solder alloy, and the cemented carbide particles are 20-30 mesh cast tungsten carbide powder, and the solder is selected QJ308, the ratio of flux to cemented carbide particles calculated by weight is 1:10. After powder feeding (mixture of cemented carbide particles and flux), drawing, straightening and other processes, the diameter is 5mm and the length is 5mm. It is a 400mm tubular brazing material, in which the brazing alloy coating layer 1 accounts for 7% of the total weight of the tubular brazing material, and the mixture 2 of cast tungsten carbide powder and flux accounts for 93% of the total weight of the tubular brazing material. Q235 carbon steel is selected as the base material, and the product of this embodiment is subjected to an abrasive wear test. The abrasive wear test is performed on the MLG-130A dry rubber wheel abrasive we...

[0023] Example 3
[0024] The brazing alloy is made of BAg50CuZnCdNi (national standard brand HL315, calculated by mass fraction percentage, Ag-Cu15-Zn17-Cd15-Ni3) with a thickness of 0.2mm, and the cemented carbide particles are 20-30 mesh cast tungsten carbide powder. , Flux chooses FB102, the ratio of flux to cemented carbide particles is 1:10 by weight, and the diameter is made after powder feeding (mixture of cemented carbide particles and flux), drawing, and straightening. A tubular brazing material with a length of 4mm and a length of 400mm, in which the brazing alloy coating layer 1 accounts for 9% of the total weight of the tubular brazing material, and the mixture of cast tungsten carbide powder and flux 2 accounts for 91% of the total weight of the tubular brazing material . Q235 carbon steel is selected as the base material, and the product of this embodiment is subjected to an abrasive wear test. The abrasive wear test is performed on the MLG-130A dry rubber wheel ...
