Title:
ALLOY DRILL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/070993
Kind Code:
A1
Abstract:
Disclosed is an alloy drill. Components of the alloy drill are: 14-30 wt% of a binder phase being one or more of Co, Ni, Fe, and Cu; 0.32-9.7 wt% of an additive being one or more of TaC, MoC, Cr3C2, and MnC; and the remainder as a hard phase being WC. In the alloy drill, WC is used as the hard phase to improve its hardness and wear resistance, Cu, Ni, Fe, or Co as the binder phase can improve its anti-corrosion performance and anti-fatigue performance, and TaC, MoC, Cr3C2, or MnC as the additive can further improve its thermal stability and wear resistance. Thus, the alloy drill has superior wear resistance and impact toughness, and also possesses excellent anti-corrosion performance and anti-fatigue performance.
