AI Technical Summary
Technical Problem
Small-diameter diamond drilling tools have difficulty fixing diamond particles during the brazing process, resulting in uneven distribution and serious loss, which affects processing accuracy and service life.
Method used
A nickel-based solder paste containing silane thermosetting resin and hydrophobic film-forming resin is used, along with a solvent of a specific composition. Diamond particles are fixed through a pre-curing process and decomposed during high-temperature brazing to ensure the welding strength of the diamond particles in the brazing layer.
Benefits of technology
This method achieves stable fixation of diamond particles during the brazing process, improves tool processing accuracy and service life, and ensures welding strength and yield.
