AI Technical Summary
Existing technologies for defect detection and repair of PCD tools are unable to effectively identify micron-sized pores and binder phase enrichment areas, and the repair methods cannot effectively restore the mechanical properties of the material, resulting in a short tool life.
An optical scanning device is used to acquire a fluorescence signal distribution map. Micro-defects are identified through image analysis and a three-dimensional coordinate model is constructed. Repair channels are formed using ultra-short pulse laser processing, and metallurgical bonding is achieved by filling a high thermal conductivity repair alloy with directional melting infiltration technology.
It enables precise location and in-situ repair of internal defects in PCD tools, significantly extending tool life and improving machining reliability.
