摘要：
A friction stirring tool and a method for removing the catalytic phase from the friction stirring tool having a superabrasive coating by chemically etching, electrolytic etching or similar means to thereby at least partially remove a portion of the secondary catalytic phase metal from the superabrasive coating to thereby enhance the thermal stability of the tool and allow for longer life and the reduction or elimination of chemical reaction between the secondary metallic phase of the tool and a workpiece .
