Terminology Pamusoro peTungsten Carbide

Nekuvandudzwa kwetekinoroji, vanhu vari kudzingirira maturusi ari nani, uye zvekushandisa pakuvaka kwavo nebhizinesi. Pasi pemamiriro ezvinhu aya, tungsten carbide inotora basa rakakosha muindasitiri yemazuva ano. Uye mune ino chinyorwa, mamwe mazwi ezve tungsten carbide achaunzwa.

1. Cemented carbide

Cemented carbide inoreva chiumbwa chine sintered chinoumbwa nerefractory metal carbides uye masimbi anosunga. Pakati pesimbi carbides, tungsten carbide, titanium carbide, tantalum carbide, uye zvichingodaro ndiwo anowanzo shandiswa carbides. Uye iyo inonyanya kushandiswa simbi binder icobalt hupfu, uye mamwe masimbi anosunga senickel, nesimbi, achashandiswawo dzimwe nguva.

2. Tungsten carbide

Tungsten carbide imhando ye simende carbide, iyo inoumbwa ne tungsten carbide poda uye masimbi anosunga. Nenzvimbo yakakwira yekunyungudika, tungsten carbide zvigadzirwa hazvigone kugadzirwa sezvimwe zvinhu. Powder metallurgy inzira yakajairika yekugadzira tungsten carbide zvigadzirwa. Iine tungsten maatomu uye kabhoni maatomu, tungsten carbide zvigadzirwa zvine akawanda makuru zvivakwa, zvichiita kuti zvive zvakakurumbira zvekushandisa muindasitiri yemazuva ano.

3. Density

Density zvinoreva chiyero chehuremu kusvika kuhuwandu hwezvinhu. Inzwi rayo rinewo vhoriyamu ye pores muzvinyorwa.

Mune tungsten carbide zvigadzirwa, cobalt kana mamwe masimbi masimbi aripo. Iyo yakajairika tungsten carbide giredhi YG8, iyo iri mukati me8% cobalt, ine density ye14.8g/cm3. Naizvozvo, sezvo iyo cobalt yemukati mune tungsten-cobalt alloy inowedzera, kuwanda kwese kunoderera.

4. Kuoma

Kuomarara zvinoreva kugona kwechinhu kuramba deformation yepurasitiki. Vickers kuoma uye Rockwell kuoma kunowanzo shandiswa kuyera kuomarara kwe tungsten carbide zvigadzirwa.

Vickers kuomarara kunoshandiswa zvakanyanya pasi rese. Iyi nzira yekuyera kuomarara inoreva kukosha kwekuomarara kunowanikwa nekuyera saizi yekumisikidza nekushandisa dhaimondi kuti ipinde pamusoro peiyo sampuli pasi peimwe mamiriro emutoro.

Rockwell kuoma ndiyo imwe nzira yekuyera kuomarara iyo inowanzoshandiswa. Inoyera kuomarara ichishandisa kudzika kwekupinda kweiyo standard diamond cone.

Ose ari maviri eVickers kuomarara nzira yekuyera uye Rockwell kuomarara nzira yekuyera inogona kushandiswa kuyera kuomarara kwesimende carbide, uye maviri anogona kushandurwa.

Kuoma kwe tungsten carbide kubva pa85 HRA kusvika pa90 HRA. Iyo yakajairika giredhi yetungsten carbide, YG8, ine kuoma kwe89.5 HRA. Chigadzirwa che tungsten carbide chine kuomarara kwepamusoro chinogona kutsungirira kukanganisa uye kupfeka zvirinani, saka chinogona kushanda kwenguva yakareba. Sechisungo, shoma cobalt inokonzera kuoma kuri nani. Uye yakaderera kabhoni inogona kuita kuti tungsten carbide iome. Asi decarbonization inogona kuita kuti tungsten carbide ive nyore kukuvadza. Kazhinji, yakanaka tungsten carbide inowedzera kuoma kwayo.

5. Kupeta simba

Muenzaniso wacho unowedzerwa sedanda rinongotsigirwa pamafurumu maviri, uye mutoro unoiswa kumutsara wepakati wemafurumu maviri kusvika sampuli yatsemuka. Iko kukosha kwakaverengerwa nemhepo inoputika inoshandiswa maererano nemutoro unodiwa pakuputsika uye nzvimbo yemuchinjikwa-chikamu chemuenzaniso. Iyo inozivikanwawo sekuti transverse rupture simba kana kukotama kuramba.

MuWC-Co tungsten carbide, simba rekuchinja rinowedzera nekuwedzera kwekobalt yemukati tungsten-cobalt alloy, asi kana cobalt yemukati inosvika 15%, iyo flexural simba inosvika pakukosha kukuru, yobva yatanga kudzika.

Simba rekukombama rinoyerwa neavhareji yezvakayerwa zvakati wandei. Kukosha uku kuchachinjawo seiyo geometry yemuenzaniso, mamiriro epamusoro, kushushikana kwemukati, uye kukanganisa kwemukati kwekuchinja kwezvinhu. Nokudaro, simba rekushanduka-shanduka rinongova chiyero chesimba, uye flexural simba value haigone kushandiswasehwaro hwekusarudza zvinhu.

6. Transverse kuputika simba

Transverse rupture simba ndiko kugona kwe tungsten carbide kuramba kukotama. Tungsten carbide ine zvirinani transverse kuputika simba yakanyanya kuoma kukuvadza pasi pesimba. Fine tungsten carbide ine zvirinani transverse rupture simba. Uye kana zvimedu zve tungsten carbide zvichigovera zvakaenzana, iyo inotenderera iri nani, uye tungsten carbide haisi nyore kukuvadza. Iyo yakachinjika kuputika simba yeYG8 tungsten carbide zvigadzirwa zvakatenderedza 2200 MPa.

7. Simba rekumanikidza

Coercive force isimba remagineti rasara rinoyerwa nekuita magineti mu carbide yakasimwa kusvika panzvimbo yakaguta yobva yaita magineti.

Pane hukama hwakananga pakati peavhareji particle size yecemented carbide phase uye simba rekumanikidza. Iyo yakatsetseka yeavhareji saizi yechikamu chemagnetized, inokwirisa kukosha kwesimba rekumanikidza. Murabhoritari, simba rekumanikidza rinoedzwa neanomanikidza simba tester.

Aya ndiwo mazwi etungsten carbide uye zvimiro zvayo. Mamwe mazwi echirevo achaunzwawo muzvinyorwa zvinotevera.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
