Cemented carbide chinhu che alloy chakagadzirwa neakaomeswa makomisheni ezve simbi dzinoramba uye masimbi ekubatanidza nehupfu metallurgy process. Inowanzo gadzirwa nezvinhu zvakapfava zvekubatanidza (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 misanganiswa yavo).
Cemented carbide ine nhevedzano yezvivakwa zvakanakisa, senge kuomarara kwepamusoro, kusapfeka, simba rakanaka uye kuomarara, kusapisa kupisa, kuomarara kwemarara, nezvimwewo, kunyanya kuoma kwayo kwakanyanya uye kusapfeka, izvo zvinoramba zvisina kushanduka kunyangwe pa500 ℃ uye zvichiri kuomarara zvakanyanya 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 semidziyo yekucheka maturusi, senge maturusi ekuchinjisa, milling cutters, planers, drill bits, boring cutters, etc., yekucheka simbi yakakandwa, isina-ferrous simbi, mapurasitiki, makemikari fibers, graphite, girazi, dombo uye simbi yakajairwa, uye zvakare nekucheka simbi isingadziviriri, simbi isina tsvina, yakakwirira manganese simbi uye imwe yakaoma kumushini simbi.
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 kwezvombo zvepamusoro-soro uye midziyo, kufambira mberi kwesayenzi uye teknolojia uye kukurumidza kukura kwesimba renyukireya kuchawedzera zvikuru kudiwa kwezvigadzirwa zve carbide zvine simiti yepamusoro uye kugadzikana kwepamusoro.
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 matombo ekuchera maturusi, maturusi emigodhi, maturusi ekuyeresa, maturusi ekuyeresa, asingapfeki mativi, simbi abrasives, silinda liners, precision bearings, nozzles, hardware molds (senge waya yekudhirowa molds, bhaudhi molds, nut molds, uye akasiyana-siyana fastener mold yesimbi yapfuura. molds).
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.
