Description
Technical field
The present invention relates to a kind of alloy material, in particular to a kind of sapphire crystal ingot draws stick drilling pipe knife.
Background technique
After the completion of sapphire crystal ingot preparation, need to dig out crystal bar with drawing stick drilling pipe, draw stick drilling pipe port be equipped with it is cricoid
Drilling pipe knife, current drilling pipe knife draw stick depth generally in 5m or so, and quality preferably most multipotency reaches 8 to 10m, can reach
10m or more depth it is very rare, drill bit mostly uses cobalt alloy as carrier, is mixed with diamond, existing brill
Pipe knife cobalt content is mostly less than 30%, because will lead to the decline of drilling pipe knife wearability after nowadays generally believing that cobalt content improves.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of sapphire crystal ingot and draws stick drilling pipe knife.
The technical solution adopted by the present invention is that: a kind of sapphire crystal ingot draws stick drilling pipe knife, including diamond and carrier alloy,
The carrier alloy includes cobalt, copper, aluminium, silver, zinc, and wherein volume ratio shared by cobalt is 65% or more, the carrier alloy and diamond
Volume ratio, i.e. diamond concentration are 42% to 55%.
A kind of sapphire crystal ingot draws stick drilling pipe knife, it is characterized in that: in the carrier alloy, aluminium, silver, body shared by zinc
Product ratio is less than 15%.
A kind of sapphire crystal ingot draws stick drilling pipe knife, it is characterized in that: the carrier alloy includes following volume ratio
Component: cobalt 68%, copper 25%, aluminium 2%, silver 2%, zinc 3%, the diamond concentration are 47%.
Cobalt content in alloy carrier is promoted to 65% or more by the present invention, and with copper, aluminium, silver, zinc is as alloy carrier and gold
Hard rock mixing, can greatly enhance the wearability of drilling pipe knife.
