Cemented carbide chinhu che alloy chakagadzirwa neakaomeswa makomisheni ezve simbi dzinoramba uye masimbi ekubatanidza nehupfu metallurgy process.Inowanzo gadzirwa neyakapfava yekubatanidza zvinhu (senge cobalt, nickel, simbi kana musanganiswa wezvinhu zviri pamusoro) pamwe nemidziyo yakaoma (senge tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide kana yavo. musanganiswa).
Cemented carbide ine nhevedzano yezvinhu zvakanakisa, senge kuomarara kwakanyanya, kusapfeka, simba rakanaka uye kuomarara, kupisa kupisa, corrosion resistance, zvichingodaro, kunyanya kuoma kwayo kwakanyanya uye kusapfeka, izvo zvinoramba zvisina kushanduka kunyangwe pa500 ℃ uye zvichiri. kuoma kwakanyanya pa1000 ℃.Mumidziyo yedu yakajairika, kuomarara kunobva kumusoro kusvika pasi: sintered diamond, cubic boron nitride, cermet, simende carbide, simbi yekumhanya-mhanya, uye kuoma kunobva pasi kusvika kumusoro.
Cemented carbide inoshandiswa zvakanyanya sekucheka maturusi emidziyo, senge maturusi ekuchinjisa, milling cutters, planers, drill bits, boring cutters, etc., kucheka simbi yakakandwa, isiri-ferrous simbi, mapurasitiki, makemikari fiber, graphite, girazi, dombo uye. simbi yakajairwa, uye zvakare yekucheka simbi inodzivirira kupisa, simbi isina tsvina, yakakwira manganese simbi, simbi yemidziyo uye zvimwe zvakaoma kumichina michina.
Cemented carbide ine kuomarara kwakanyanya, simba, kupfeka kusamira uye kusaita ngura, uye inozivikanwa se "meno eindasitiri".Inoshandiswa kugadzira maturusi ekucheka, maturusi ekucheka, maturusi ecobalt uye zvikamu zvinopfekwa.Inoshandiswa zvakanyanya muindasitiri yemauto, aerospace, machining, metallurgy, kuchera mafuta, maturusi emigodhi, kutaurirana kwemagetsi, kuvaka uye mamwe minda.Nekuvandudzwa kwemaindasitiri epasi, kudiwa kwemusika wecemented carbide kuri kuwedzera.Uye mune ramangwana, kugadzirwa kwepamusoro-tekinoroji zvombo nemidziyo, kufambira mberi kwehunyanzvi hwesainzi uye tekinoroji uye kukurumidza kukura kwesimba renyukireya kuchawedzera zvakanyanya kudiwa kwezvigadzirwa zvesimende zvecarbide zvine hunyanzvi hwepamusoro uye kugadzikana kwemhando yepamusoro. .
Muna 1923, schlerter yekuGermany yakawedzera 10% - 20% cobalt kune tungsten carbide powder sebinder, uye akagadzira alloy itsva ye tungsten carbide necobalt.Kuoma kwayo ndekwechipiri chete kudhaimondi, inova yekutanga kugadzira simende carbide munyika.Paunenge uchicheka simbi nechishandiso chakagadzirwa neiyi alloy, blade ichapfeka nekukurumidza, uye kunyange blade ichatsemuka.Muna 1929, schwarzkov wekuUnited States akawedzera humwe huwandu hwemakomboni etungsten carbide uye titanium carbide kune yekutanga kuumbwa, iyo yakavandudza kushanda kwesimbi yekucheka maturusi.Uku ndiko kumwe kubudirira munhoroondo yekusimudzira carbide.
Cemented carbide inogonawo kushandiswa kugadzira maturusi ekuchera matombo, maturusi ekuchera, maturusi ekuyeresa, masimbi asingapfeki, mabrasives esimbi, macylinder liners, precision bearings, nozzles, hardware molds (senge waya yekudhirowa molds, bolt molds, nati. molds, uye akasiyana fastener molds.Kuita kwakanakisa kwecemented carbide kwave kutsiva zvishoma nezvishoma zviumbwa zvesimbi zvekare).
Mumakumi maviri emakore apfuura, yakavharwa simende carbide yakaonekwa zvakare.Muna 1969, Sweden yakabudirira kugadzira titanium carbide coated tool.Iyo substrate yechishandiso ndeye tungsten titanium cobalt simende carbide kana tungsten cobalt simende carbide.Ukobvu hwetitanium carbide coating pamusoro ingori mashoma mamicrons, asi kana ichienzaniswa nealloy maturusi emhando imwe chete, hupenyu hwesevhisi hunowedzerwa nekatatu, uye kumhanya kwekucheka kunowedzerwa ne25% - 50%.Chizvarwa chechina chezvishandiso zvekupfekedza chakaonekwa muma1970, chinogona kushandiswa kucheka zvinhu zvakaoma kuchina.
