The method for fabricatiing ultrafine crystalline TiN/TiB2 composite cermet

摘要

invention nanocrystalline titanium nitride / titanium complex boride cermet according to the production method, in particular titanium (Ti) and boron nitride (BN) and stainless steel (stainless steel) by the titanium nitride powder as a raw material powder by the milling reaction (reaction milling) (TiN) / titanium boride (TiB ₂ ) / producing a nanocomposite powder of stainless steel, and is prepared by sintering a nano-composite powder liquid to a method for producing the ultrafine titanium nitride / titanium boride cermets. ; nanocrystalline nitride of the present invention titanium / titanium composite boride cermet powder and a method for producing the titanium boron nitride powder 3: a first step of mixing at a molar ratio of 2, a second step of mixing an additional 5-60% by weight of stainless steel powder in the mixed powder; The mixed powder was introduced to the reaction vessel with a ball of a predetermined diameter and then by performing a high-energy ball milling titanium nitride / titanium boride / stainless steel third step to produce a nano-composite powder; And a fourth step of forming and sintering the resulting nanocomposite powder; comprises
