[0140] The tungsten alloy diamond wire of this specific embodiment has high high temperature strength, corrosion resistance and ductility. Rhenium (Re) can improve the high temperature strength and wear resistance of the alloy; lanthanum (La), cerium (Ce) and yttrium (Y) as rare earth elements can improve the microstructure of the alloy and improve its corrosion resistance and ductility; nickel (Ni) can enhance the toughness and corrosion resistance of the alloy. Tungsten (W) as a substrate has a high melting point and good high temperature stability. The above-mentioned tungsten alloy diamond wire is widely used in equipment and devices in high temperature environments, such as aerospace, energy and electronics.

[0141] This specific embodiment ensures the high quality and durability of the tungsten wire through fine cleaning and pre-plating steps. Through multiple cleaning processes such as alkaline washing and water washing, the cleanliness of the surface of the tungsten wire busbar is ensured, and grease, oxides and other impurities are removed, providing a good foundation for subsequent processing steps. The pre-plating step forms a protective film on the surface of the tungsten wire busbar, which helps to improve the effect of subsequent processing and enhance the corrosion resistance and adhesion of the tungsten wire busbar. The sanding step increases the roughness and adhesion of the surface of the tungsten wire busbar, provides a better foundation for subsequent thickening processing, and improves the quality and performance of the product. The thickening step increases the thickness and strength of the tungsten wire busbar, improves its performance, and makes it more suitable for various application scenarios. The water washing and drying steps after thickening ensure the cleanliness and dryness of the surface of the tungsten wire busbar, and avoid the influence of residual chemicals and moisture on product quality.

[0142] The online photography step uses a camera to take pictures to facilitate subsequent quality inspection and control, ensuring that each batch of products meets quality standards. The wire-receiving step uses a wire-receiving machine to rewind the wire, and then conducts inspection, packaging and storage to ensure the quality of the tungsten alloy diamond wire saw, and properly stores and transports it to avoid damage during transportation.

[0143] The above production process ensures the high quality and high performance of the tungsten wire busbar through the synergistic effect of multiple steps, meeting the needs of different application scenarios.
