There are a lot of difficulties that are badly in need of solving when solder of diamond drill rod

1, makings of request drill rod has crackajack wellability and connection strength to diamond and carcass;

2, of data of drill rod solder and skill of drill rod solder choose the stability that should assure diamond, be opposite with cut down or preventing drill rod to expect of diamond corrode;

3, the distinction of hot coefficient of expansion because of diamond and metallic matrix is bigger, because this solders remaining stress is greater also, drop the intensity of contact;

4, the working temperature that the melting point that drill rod expects wants thing of prep above diamond, answer so look for melting point is inferior the metal that gets close to with diamond coefficient of expansion (alloy) the data expects as drill rod, afterthought take an examination ofing attends certain and active element to be mixed in order to improve to the wellability of diamond endophilicity, arrive already can felt diamond the intent of function of machinery of can satisfactory carcass.

In addition, of the finishing method of diamond appearance metallization, outside metal and drill rod makings match and choose, brazing flux is amiable of body medium choose wait for crucial skill to still need farther adept and optimize.

The nominal power of locomotive of diamond thing and birthday number are divided depend on bead of King Kong stone mill is borne fruit by inlaid outside degree, still concern with the wearability of carcass. The metropolis such as the chroma of the dispersed state in carcass, diamond is opposite the concave and convex, diamond of carcass oneself intensity the wearability of carcass produces an effect, so, the state that how makes carcass arrives at aspiration also is the notable doubt in job of in the future.

Skill of drill rod solder is achievable agent of diamond, connection (data of gold of drill rod seam) with chemistry of metallic matrix interface metallurgy is contacted, have higher connection strength. Because the connection intensity on the interface is high, need very thin connection agent ply to operate strongly with respect to enough only so wear bead, its expose height to be able to amount to 70% ～ 80% , make the use all the more of abrasive sufficient, the life that improved a thing greatly is counted and machine power. Compare with traditional mastery of a skill or technique, of diamond thing promise the greatest value giving blade to be able to increase 50% above, below the condition that be not added in the power comsumption of the thing or drops somewhat, the diamond cost amount of data of the workpiece on unit volume cuts down half above. With eletroplate the thing is compared, also showed unique advantage. After all, skill of drill rod solder is having wonderful development perspective in the diamond thing process that make, answer to make this one skill finishs industrialization as soon as possible.
