Method to improve the performance of a leached cutter

摘要

A cleaned leached component having a polycrystalline structure, a method and apparatus for cleaning a leached component to form the cleaned leached component, and a method for determining the effectiveness of cleaning the leached component. The clean leached component includes at least a leached layer. The leached layer has at least a portion of a by-product materials removed from therein. The by-product materials were deposited into the leached layer during a leaching process that forms the leached layer. The apparatus and method for cleaning includes a tank, a cleaning fluid placed within the tank, and at least a portion of the leached layer immersed into the cleaning fluid. In certain exemplary embodiments, a transducer emits ultrasonic waves into the leached layer. The method for determining the effectiveness of cleaning includes cleaning the leached component to form the cleaned leached component, measuring one or more capacitance values of the cleaned leached component, repeating the cleaning and the measuring until a stable lower limit capacitance value is achieved.
