answer reward question has expired compare with pcd, single crystal diamond submit other answers - - : : cvd diamond has the advantages of single crystal diamond and polycrystalline diamond (pcd). first of all, cvd diamond contains no metal binder and has the lowest impurity content, so its hardness...
answer reward deadline - - : : deposition time submit other answers - - : : the growth rate of the nano-diamond film is very slow, and the conventional diamond film layer has not been completely covered, and the corners of the conventional diamond particles are also exposed on the outer surface. as the...
high-energy ball grinding;then according to the specified proportion of the weight of the cemented carbide components, and to strengthen the ball grinding, then the ball grinding of the cemented carbide mixture for vacuum sintering. the main materials are: tungsten carbide (wc), titanium carbide tc. submit other...
submit other answers - - : : any metal or semi-metal that is alloyed with carbon for the most part is called a carbide. tungsten carbide is one of the most common carbides, so you are right, they usually just call tungsten carbide plain old "carbide" a few carbides-- tungsten carbide titanium carbide...
submit other answers - - : : yes, but "solid carbide" is a bit of a misnomer, because invariably it is not an actual single block of tungsten carbide, it is actually tungsten carbide powder in a nickel, cobalt, or cobalt chromium binder and it is sintered into a solid part. you can have a "solid" carbide...

submit other answers - - : : alloys are mixtures of two metals and not minerals. gold and iridium are the only two metals found naturally as alloys. gold is alloyed with a semi metallic element called tellurium and iridium forms a natural alloy with the metal osmium called osmiridium. actual minerals...
submit other answers - - : : there are two types of alloys: substitutionally alloys: element with similar chemical properties and size. atoms of another element kind of "replaces" some of the cations in the metallic lattice. interstitial alloys: atoms with a large difference in size. the smaller atom...
submit other answers - - : : in arc welding, you build up a high voltage between an electrode and your work surface, which consists of two separate pieces of metal. when you bring the electrode near the parts you want to weld, this high voltage creates a spark, which is hot enough to melt some of the...
submit other answers - - : : welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. this is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle) that cools to become a strong joint...
