摘要： An acoustic emissions testing device (505) includes a testing sample (100), an acoustic sensor (570) communicably coupled to the testing sample (100), and a load (580) that is exerted on the sample. The sensor detects one or more acoustic events occurring within the sample. The acoustic sensor (570) transmits data to a data recorder (590), which includes a processor (1020) and storage medium (1040) for executing instructions provided by a software residing within the storage medium (1040). Upon executing the instructions on the transmitted data, the toughness of the sample is objectively determined and can be ranked comparatively to the toughness of other samples. The instructions provide for categorizing the data into possible acoustic event points (1964) and background data points (1962), interpolating a background noise curve (1970), determining the actual acoustic event points (2010), and calculating the area (2040) under each actual acoustic event point. In some embodiments, a graphical representation of the cumulative area for each actual acoustic event point is plotted against the corresponding load.

摘要： A catalyst removal apparatus and method for removing catalyst from a polycrystalline cutter. The cutter includes a substrate and a cutting table. The apparatus includes a tank forming a cavity therein, an electrolyte fluid occupying the cavity, the cutter, a covering surrounding at least a portion of the cutter's sidewall and extending from at least the substrate's top surface towards the bottom surface, a cathode submersed within the fluid, and a power source. The cutting table is submersed within the fluid and positioned near the cathode, thereby forming a gap therebetween. The power source is coupled to the cutter and the cathode and electrolyzes the fluid to react with the catalyst in the cutting table to produce a salt. The salt dissolves in the fluid and is removed from the cutter.
