Embodiment 1

[0011] A superhard alloy drill bit, the material of which is composed of the following materials: 5 tons of molybdenum, 6 tons of nickel, 6 tons of hafnium, 2 tons of titanium, 2 tons of chromium, 2 tons of silicon, 30 tons of titanium, 1 ton of boron, 0.5 tons of vanadium and 0.1 tons of niobium. The preparation process of the above-mentioned superhard alloy drill bit is to cast the metal substances into electrodes, and then remelt the electrodes into ingots by electroslag, heat the alloy ingots and then reverse the drill bit molds to obtain superhard alloy drill bits.

Embodiment 2

[0013] A superhard alloy drill bit, the material of which is composed of the following materials: 11 tons of molybdenum, 8 tons of nickel, 15 tons of hafnium, 3 tons of titanium, 3 tons of chromium, 3 tons of silicon, 36 tons of titanium, 2 tons of boron, 2 tons of vanadium and 0.5 tons of niobium. The preparation process of the above-mentioned superhard alloy drill bit is to cast the metal substances into electrodes, and then remelt the electrodes into ingots by electroslag, heat the alloy ingots and then reverse the drill bit molds to obtain superhard alloy drill bits.

Embodiment 3

[0015] A superhard alloy drill bit, the material of which is composed of the following materials: 8 tons of molybdenum, 7 tons of nickel, 10 tons of hafnium, 2 tons of titanium, 2 tons of chromium, 3 tons of silicon, 32 tons of titanium, 1 ton of boron, 1 ton of vanadium and 0.5 tons of niobium. The preparation process of the above-mentioned superhard alloy drill bit is to cast the metal substances into electrodes, and then remelt the electrodes into ingots by electroslag, heat the alloy ingots and then reverse the drill bit molds to obtain superhard alloy drill bits.

Abstract

The present invention disclosed a super hard-hard alloy drill., 2-3 copies of chromium, 2-3 parts of silicon, 30-36 parts of titanium, 1-2 parts of boron, 钒 0.5-2 parts, 铌 0.1-0.5 copies, and provide their preparation technology.The beneficial effect of the present invention is: an ultra-hard-hard alloy drill and its preparation process provided by the present invention. The hardness of the drill is 8-10 times that of the existing products. At the same time, its toughness has also increased greatly.The toughness of the alloy drill provided by the present invention can increase by more than 20%.

Description

technical field [0001] The invention relates to the field of alloy parts, in particular to a superhard alloy drill bit and a preparation process thereof. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills and casing drills. In the prior art, drill bits are usually made of cemented carbide, but there are the following defects: [0003] 1. The hardness is insufficient, and the wear rate of the drill bit is relatively large; [0004] 2. The toughness is not enough. When acting on solid materials with high hardness, the drill bit is easy to break. Contents of the invention [0005] The object of the present invention is to provide a superhard alloy drill bit with a hardness far exceeding that of the previous products and with a certain toughness in view of the above-mentioned defects in the prio...
