#CMT# #/CMT# The method involves placing connection surfaces of a block by supporting one on another directly or by a layer constituted of filler material, which is placed between supporting surfaces of two blocks. The binder phase material is enriched by migrating of a binder phase by the connection surfaces of the blocks, which are made of two materials such as chemical composition of carburized metal that is manganese, chromium, molybdenum, tungsten, vanadium, tantalum, titanium, zirconium and hafnium. The metal of binder phase is selected from cobalt, copper, nickel, iron and silicon. #CMT#USE : #/CMT# Method for assembling density material or non density material blocks of a bit of a tool such as tricone bit, polycrystalline diamond composite tool and a thermally stable polycrystalline tool, of drilling oil or mining or civil engineering industry or excavation of ground or under ground (all claimed) for fabricating composite materials such as cermets. Can also be used for a cutting or splintering or drilling tool for cutting or crushing the hard rock, a metal fabrication tool and a crusher in a tunnel boring machine, drilling machine, chute, rotative or roto-hammer drilling bore-bit. #CMT#ADVANTAGE : #/CMT# The method allows fabricating the composite materials such as cermets constituted of hard particles dispersed in the binder phase by assembling the material blocks without requiring the filler material, while returning the undetectable interface with the cermets of composition of unchanged binder phase. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation of liquid migration pressure of two different cermets with respect to the volumetric fraction of the liquid in cermets, to a considered temperature. |
