The influence of construction of interface of diamond of drill rod solder and microcosmic depict to thing function

Of construction of interface of diamond of drill rod solder and microcosmic depict make influencing factor a lot of, main factor is drill rod makings and technology (include atmosphere of drill rod solder) different. What drill rod expects alloy is commonly used is main have Ni-Cr, ag-Cu, the alloy of the system such as Cu-Sn. Among them the Cr in Ni-Cr alloy is strong carbide makes an element, can generate with diamond echo a series of carbide, wait like Cr3C2, Cr7C3, Cr23C6; In Ag-Cu and Cu-Sn alloy general also the Ti that demand attends to be measured certainly or Cr element, the carbide of TiC or Cr can be formed with diamond in drill rod solder, make diamond and chemistry of metallurgy of thing carcass implementation are contacted, progress then the steering force to diamond. But, the delibrate that to diamond thing the interface constructs and microcosmic depict and diamond thing function contact is less.

The interface of diamond of drill rod solder is tectonic
Drill rod guesses attend strong carbide to make an element (be like: Ti, Cr, W) , can alter when drill rod solder the damp sex of diamond appearance, form the carbide of ascensive diamond steering force on diamond and interface of drill rod makings.

(1) the interfacial construction that the interface of diamond makes TiC increases pink of Ti Cr metal in alloy of makings of Ag-Cu-Zn drill rod and diamond, improve Ag-Cu-Zn drill rod to expect alloy is right the delibrate of the function of drill rod solder of diamond thing indicates, addition Ti pink requirement enclothes C pink or assure diamond thing obtain result of crackajack drill rod solder quite in the ability in vacuum, expect in drill rod - the rich volume section of the element of Ti of interfacial place discovery of diamond, progressed alloy of drill rod makings pursues to the damp sex of diamond 1 21 increases Ti pink to be in vacuum, diamond of drill rod solder the interface is microcosmic and tectonic between drill rod makings and matrix graph. Graph 1 (B) can observe 3 different successional area: Alloy of drill rod makings, transfer layer and diamond. The course is in graph 1 (A) in take 3 gradually the drop that approach faces diamond interface, nod to 3 do can chart analyses discovery, stand by diamond interface place to have higher Ti content, ti is blended in mediumly in alloy be helpful for increasing drill rod to expect the damp sex to diamond,
