Density or non density material block assembling method for drilling tool, involves enriching binder phase material by migrating of binder phase by connection surfaces of density or non density material blocks
Density or non density material block assembling method for drilling tool, involves enriching binder phase material by migrating of binder phase by connection surfaces of density or non density material blocks
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.
