Ndi kupita patsogolo kosalekeza kwa sayansi ya zida, kupanga ndi kugwiritsa ntchito kwapadera kwa tungsten carbide kukulitsa kugwiritsa ntchito masamba a tungsten carbide. Powonjezera ma alloying, kukhathamiritsa njira zochizira kutentha, ndikuwongolera matekinoloje ochiritsira pamwamba, masamba amtsogolo a tungsten carbide akuyembekezeka kukhalabe ndi magwiridwe antchito abwino kwambiri m'malo owononga ambiri, ndikupereka mayankho odalirika komanso ogwira mtima ogwirira ntchito m'mafakitale osiyanasiyana.
1. Za Tungsten Carbide Blades
Tungsten carbide, yomwe imadziwika kuti cemented carbide, ndi chinthu cha alloy chomwe chimapangidwa ndi tungsten carbide, chomwe chimapangidwa kudzera muzitsulo za ufa. Amadziwika ndi kuuma kwakukulu komanso kukana kwamphamvu kwambiri, kusunga kuuma kwake kosasinthika ngakhale pa 500 ° C ndipo kumakhalabe ndi kuuma kwakukulu pa 1000 ° C. Kuchita kwapadera kumeneku kumapangitsa tungsten carbide kukhala chisankho chabwino kwambiri popanga zida zodulira zapamwamba kwambiri, zomwe zimagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zodulira monga zida za lathe, odulira mphero, okonza mapulani, kubowola, ndi zida zotopetsa.
Masamba amakono a tungsten carbide amapangidwa makamaka ndi zigawo ziwiri zofunika: tungsten carbide ndi cobalt. Gawo lolimba la tungsten carbide limapereka kuuma kwambiri komanso kukana kuvala komwe kumafunikira pa tsamba, pomwe gawo la cobalt binder limapereka kulimba kwina kwazinthuzo. Mu mawonekedwe a masamba a tungsten carbide, tungsten carbide ndi cobalt amapanga 99% ya zonse, ndi zitsulo zina zimapanga 1%. Kapangidwe kake kakang'ono kamene kamapangitsa masamba a tungsten carbide kukhala olimba osatheka chifukwa cha chitsulo chothamanga kwambiri komanso kukana kuvala kuposa chitsulo wamba wamba, chomwe chimakhala ndi udindo waukulu pantchito yokonza makina.
Ndi kupita patsogolo kwa sayansi ya zinthu, banja la tungsten carbide lapanganso magiredi apadera osiyanasiyana, kuphatikiza angapo angapo monga ma tungsten carbide osamva kwambiri, tungsten carbide osagwira kwambiri, tungsten carbide osatentha kwambiri, osagwira maginito tungsten carbide, ndi tinthu tating'ono tating'ono tating'ono. Zida zopangidwa mosiyanasiyana za tungsten carbide zimapereka mayankho okhathamira pazinthu zosiyanasiyana zogwiritsira ntchito. Mwachitsanzo, tungsten carbide yolimbana ndi dzimbiri yomwe imagwiritsidwa ntchito m'malo amankhwala imatha kuwonjezera zinthu monga chromium ndi faifi tambala kuti ipititse patsogolo mphamvu zake zoletsa dzimbiri.

Kuwunika kwa Corrosion Resistance Performance ya Tungsten Carbide Blades
1. Njira Zopewera Kuwonongeka kwa Ziphuphu ndi Makhalidwe
Kukana kwa dzimbiri kwa masamba a tungsten carbide makamaka kumachokera ku kapangidwe kake kapadera ka mankhwala ndi ma microstructure. Tungsten carbide yoyambira imakhala ndi tungsten carbide ndi cobalt. Tungsten carbide palokha imakhala ndi kukhazikika kwamankhwala ndipo imatha kukana kukokoloka ndi ma media osiyanasiyana. Gawo la cobalt binder lingathenso kupanga oxide oxide wosanjikiza kutentha kwa firiji, ndikuchepetsanso njira ya dzimbiri. Pakugwiritsa ntchito, tungsten carbide imawonetsa kukana kwina kwa ma acid, alkalis, madzi amchere, ndi mankhwala ena, kuwalola kuti azigwira ntchito mokhazikika m'malo owononga osiyanasiyana.
Kafukufuku akuwonetsa kuti kukana kwa dzimbiri kwa tungsten carbide ndikwabwino kwambiri m'malo enaake. Mwachitsanzo, pamayeso a aluminiyamu amadzimadzi amadzimadzi, kuchuluka kwa dzimbiri kwa tungsten koyera kumakhala pafupifupi 1/14 kokha kwachitsulo cha H13, kuwonetsa kukana kwa dzimbiri. Kuchita bwino kwambiri kwa anti-corrosion kumeneku kumapangitsa tungsten carbide kukhala njira yabwino yosinthira chitsulo chachikhalidwe m'makampani opangira zida komanso malo am'madzi otentha kwambiri. Momwemonso, pakuyesa kwa dzimbiri kwa ma aloyi amphamvu yokoka amtundu wa tungsten, ofufuza adapeza kuti zidazi nthawi zambiri zimakhala ndi dzimbiri zolimba, zimasunga umphumphu wokhazikika pambuyo poyesa kumiza dzimbiri mu labotale komanso mayeso okhudzana ndi chilengedwe.
2. Makhalidwe Apamwamba ndi Makhalidwe Owononga
Kukana kwa dzimbiri kwa masamba a tungsten carbide sikutengera zinthu zokhazokha komanso makamaka pamtunda wake komanso pambuyo pokonza. Pansi bwino komanso opukutidwa pa tsamba la tungsten carbide amatha kupanga chosanjikiza chodzitchinjiriza, kutsekereza bwino kulowerera kwa media zowononga. Masamba ena apamwamba kwambiri a tungsten carbide amagwiritsanso ntchito ukadaulo wokutira pamwamba (monga TiN, TiCN, DLC, ndi zina), zomwe sizimangowonjezera kudulidwa kwa tsamba komanso kumathandizira kwambiri kukana dzimbiri.
Ndikofunika kuzindikira kuti kukana kwa dzimbiri kwa tungsten carbide sikokwanira. Kafukufuku akuwonetsa kuti pakuwonetseredwa kwachilengedwe kwanthawi yayitali, gawo lomangira muzinthu zamtundu wa tungsten limakhala ndi chizolowezi chowononga, zomwe zingayambitse kuchepa kwa pulasitiki. Chodabwitsa ichi chimapezekanso mu tungsten carbide wamba yokhala ndi gawo la cobalt binder. Mukakhala m'malo owononga kwambiri monga chinyezi ndi kutsitsi mchere, gawo la cobalt likhoza kuonongeka bwino, potero limakhudza momwe tsambalo likuyendera. Chifukwa chake, kusankha magiredi a tungsten carbide omwe amatetezedwa mwapadera kuti asachite dzimbiri ndikofunikira kwambiri pamagwiritsidwe ntchito omwe ali ndi chiopsezo chachikulu cha dzimbiri.
3. Kukula ndi Kupita patsogolo kwa Tungsten Carbide yolimbana ndi dzimbiri
Kuti akwaniritse zosowa zamagwiritsidwe ntchito m'malo ovuta kwambiri monga mafakitale amankhwala ndi am'madzi, asayansi azinthu apanga mitundu ya tungsten carbide yosagwirizana ndi kutu. Ma tungsten carbides apamwambawa amathandizira kwambiri kukhazikika kwazinthu zakuthupi powonjezera zinthu zophatikizika monga chromium, faifi tambala, ndi molybdenum ku formula yachikhalidwe. Mwachitsanzo, tsamba lovomerezeka lopangidwa ndi ma fiber osagwirizana ndi dzimbiri la sulfuric acid limachepetsa kuphulika kwa tungsten carbide palokha kudzera munjira zapadera zoziziritsira, kupangira, komanso kutentha kwamafuta, ndikupangitsanso tsambalo kukana dzimbiri la sulfuric acid.
