METAL MATRIX COMPOSITE MATERIAL FOR ADDITIVE MANUFACTURING OF DOWNHOLE TOOLS

A downhole cutting tool includes a tool body with a cutting element or cutting element pocket thereon. At least a portion of the tool body or an attachment thereto is a metal matrix composite formed from metal carbide particles dispersed in a continuous metal matrix. The metal carbide particles make...

Beschreibung
Zusammenfassung:	A downhole cutting tool includes a tool body with a cutting element or cutting element pocket thereon. At least a portion of the tool body or an attachment thereto is a metal matrix composite formed from metal carbide particles dispersed in a continuous metal matrix. The metal carbide particles make up less than 45 wt % of the metal matrix composite and/or less than 30 vol % of the metal matrix composite. The continuous metal matrix may also be formed from a metal or metal alloy other than Ni-Si-B and/or have a transverse rupture strength greater than 150 ksi and a fracture toughness over 22 ksi*in0.5.
