Abstract
Description
本発明によるインサートは、まず、イータ相もグラファイトも含まない従来の超硬合金、第1の超硬合金ホディを作製することにより作製される。第1の超硬合金ホディはまた、どのような結合相成分も含まない。次いで、第1の超硬合金ホディは、浸炭環境において実施される第2の焼結工程に供される。
WC、6wt%のCoと追加の炭素との混合物を、混合し、18時間にわたってブレンドし、押し出し、1410℃で1時間にわたり真空条件下で焼結した。焼結後、超硬合金は、Co金属結合相に埋設されたWCを含んでいた。焼結後にLECOによって測定された総炭素は5.76wt% Cであった。炭素含有量は実施例1に記載されたように測定された。グラファイトの勾配は存在せず、Cポロシティは検出できなかった。この超硬合金ホディを試料2と呼ぶ。
