Chii chinonzi tungsten carbide?

Tungsten carbideis inozivikanwawo secemented carbide. Tungsten carbide imhando yealloy material ine refractory tungsten (W) material micron poda sechinhu chikuru chinosanganisa, chinowanzobva muchikamu chiri pakati pe70% -97% yehuremu hwese, uye Cobalt (Co), Nickel (Ni), kana Molybdenum. (Mo) sebhainda.

Parizvino, W muchimiro cheWCinonyanya kushandiswa mukugadzirwa kwecemented carbide.tungstencarbide chinhu chinoumbwa nekusunga zvakanyanya kuomarara imwe WC zvimedu mune yakaoma cobalt (Co) binder matrix nemvura-chikamu sintering. Pakupisa kukurus, WC yakanyungudika zvakanyanya mucobalt, uye liquid cobalt binder inogonawo kugadzira WC mukunyorova kwakanaka, izvo zvinotungamira kune yakanaka compactness uye isiri-pore chimiro mukuita kwemvura-chikamu sintering. Naizvozvo, tungsten carbide ine nhevedzano yezvakanakisa zvivakwa, senge:

*kuoma kwakanyanya:Mohs’kuomarara kunonyanya kushandiswa mumamineral classification. The Morse scale inobva1ku10(Iyo yakakura nhamba, iyo yakakwirira kuoma).Iyo Mohs 'kuoma kwe tungsten carbide ndeye9 kusvika 9.5,Inozvirumbidza pamwero wekuoma kwechipiri kune diamondizvo kuoma kuri 10.

* kupfeka kuramba: Iyo yakakwirira iyo kuoma, zviri nani kupfeka kuramba kwe tungsten carbide

*kupikisa kupisa: Sezvo iine simba repamusoro pakupisa kwepamusoro uye yakaderera kupisa kwekuwedzera coefficient, ndiyo yakakwana mbishi zvinhu zvekucheka maturusi kuti ashandiswe munzvimbo yakakwirira-yekupisa uye yekumhanya-mhanya.

*Corrosion resistance: Tungsten carbide chinhu chakanyanya kugadzikana, chisingagoni kunyungudika mumvura, hydrochloric acid kana sulfuric acid. Mukuwedzera, hazvibviri kuumba mhinduro yakasimba ine zvinhu zvakasiyana-siyana, uye inogona kuchengetedza unhu hwakagadzikana kunyange munzvimbo dzakaoma.

Kunyanya kuoma kwayo kwepamusoro uye kushorwa kwekushisa, iyo inoramba isina kushanduka kunyangwe pa1000 ℃. Nezvakawanda zvakanakira, tungsten carbide inogona kushandiswa kugadzira maturusi ekucheka, mapanga, maturusi ekuchera, uye asingapfeki zvikamu, uye inoshandiswa zvakanyanya muindasitiri yemauto, aerospace, mechanic processing, metallurgy, petroleum drilling, zvicherwa zvemagetsi. kutaurirana, kuvaka, uye mamwe minda. Ndicho chikonzero nei ichizivikanwa se "meno eindasitiri".

Tungsten carbide yakasimba ka2-3 sesimbi uye ine simba rekumanikidza rinopfuura zvese zvinozivikanwa zvakanyungudutswa, kukanda, uye simbi dzakagadzirwa. Inonyanya kupikisa deformation uye inochengetedza kugadzikana kwayo pane zvose zvinotonhora zvakanyanya uye kupisa kwekushisa. Kuramba kwayo, kuomarara, uye kuramba marara/abrasions/rosion zvakasarudzika, zvinogara kusvika ka100 kureba kupfuura simbi mumamiriro akanyanya. inoita kupisa nekukurumidza kupfuura simbi yekushandisa. Tungsten carbideinogona zvakare kukandwa uye nekukasira kudzimwa kuti igadzire yakanyanya kuomarara chimiro chekristaro.

Nekuvandudzwa kwetheindasitiri yepasi, kudiwa kwemusika kwe tungsten carbide kuri kuwedzera. Uye mune ramangwana, kugadzirwa kwemidziyo yezvombo zvemhando yepamusoro, kufambira mberi kwesainzi & tekinoroji, uye kukurumidza kukura kwesimba renyukireya kuchawedzera zvakanyanya kudiwa kwezvigadzirwa zvesimende zvecarbide zvine tekinoroji yepamusoro uye yakakwirira.-kugadzikana kwehutano.
