Description
Technical field
Present invention relates particularly to a kind of high heat-resisting boride-base cerment mould and preparation side thereof
Method.
Background technology
Ceramic metal English word cermet or ceramet be by ceramic (ceramic) and
Metal (metal) is bonded.Ceramic metal refers to the gold prepared with powder metallurgy process
Belonging to and the composite of pottery, ceramic metal has metal and the advantage of pottery concurrently, its density is little,
Hardness is high, wear-resisting, heat conductivity is good, will not be because of quenching or shock heating and embrittlement.Ceramic metal was both
There is the toughness of metal, high-termal conductivity and good heat stability, there is again the resistance to height of pottery
The characteristic such as warm, corrosion-resistant and wear-resistant.Ceramic metal is in Aero-Space, defence and military, essence
The fields such as close manufacture are gathered around and are had broad application prospects.Boride-base cerment be with titanium boride,
Tantalum boride, vanadium boride, chromium boride, zirconium boride, tungsten boride, molybdenum boride, niobium (Nb) boride, boronation
Hafniums etc. are matrix, form with part metals Material cladding.
Mould be communication equipment, industrial devices, auto parts and components manufacture in indispensable heavy
Equip, but the working environment of mould, as huge pinch shock, flowing friction etc. all can
Causing, mold temperature raises, so it occur frequently that phenomenons such as mould sticking to mould, seam or oxidations,
These all exacerbate die wear and reduce die life.But it is higher that hot extrusion process produces
Temperature would generally make mold materials soften and wearability decline, reduction in service life and product
Surface quality is poor.Cermet material not only has high intensity and high rigidity, high temperature resistant and wear-resisting
The advantages such as damage, and there is preferable antioxidation and chemical stability.The most extraordinary
Application prospect.In the market for having high heat-resisting boride-base cerment mould demand day
Benefit is all to be increased, but does not has corresponding product the most corresponding.The heat-resisting boronation of rare height on domestic market
Thing based ceramic metal mould, a small amount of sale and public praise are preferably substantially imported product, domestic
The market share of product is less.To this end, we set about from formula and the technique of product, exploitation
New high performance material, it is provided that a kind of high heat-resisting boride-base cerment mould and preparation side thereof
Method.
