Iyo yenyama pfuma ye tungsten carbide

Tekinoroji yemazuva ano ine huwandu hwakawanda hwekushandisa kune yakasarudzika alloy tungsten-cobalt. Nei yakakurumbira kudaro? Heano mamwezvinhu zvemuviri ye tungsten carbide. Mushure mekuverenga ndima iyi iwe unozoziva zvakawanda pamusoro payo.

Kuoma.

Isu tese tinoziva kuti dhaimondi ndechimwe chezvinhu zvakaoma zvechisikigo munyika. Nepo kuoma kwe tungsten carbide kuri kwechipiri kune diamond.Kuomarara ndechimwe chezvinhu zvikuru zvemakina ecemented carbide. Nekuwedzera kwekobalt yemukati mune alloy kana kuwedzera kwecarbide saizi yezviyo, kuoma kweiyo alloy kunoderera. Semuenzaniso, kana cobalt yemukati yeindasitiri WC-Co ichiwedzera kubva pa2% kusvika 25%, kuoma kwealloy kunoderera kubva pa93 kusvika pa86. Pazvese 3% kuwedzera kwecobalt, kuoma kwealloy kunoderera ne1 degree. Kuchenesa saizi yezviyo ye tungsten carbide inogona kunyatso kuvandudza kuoma kweiyo alloy.

Kupeta simba.

Kufanana nekuoma, kubhenda simba ndechimwe chezvinhu zvikuru zvesimende carbide. Pane zvakawanda zvakaoma zvinhu zvinokanganisa kubhenda kwesimba reiyo alloy, Kazhinji kutaura, kubhenda kwesimba reiyo alloy kunowedzera nekuwedzera kweiyo cobalt yemukati. Nekudaro, kana iyo cobalt yemukati inopfuura 25%, iyo yekukotama simba inoderera nekuwedzera kweiyo cobalt yemukati. Nezve maindasitiri WC-Co alloy ine chekuita, iyo yekukotama simba reiyo alloy inogara ichiwedzera nekuwedzera kweiyo cobalt yemukati muhuwandu hwe0-25%.

Kudzvinyirira simba.

Iyo yekumanikidza simba yecemented carbide inoratidza kugona kuramba kumanikidza mutoro.Nokuwedzera kwekobharitikugutsikana uye kuwedzera nehukuru hwezviyo zve tungsten carbide chikamu mune alloy tiye anomanikidza simba reWC-Co alloy inoderera. Naizvozvo, iyo yakatsetseka-zviyo alloy ine yakaderera cobalt yemukati ine yakakwirira yekumanikidza simba.

Impact kuoma.

Impact kuoma kwakakosha tekinoroji indekisi yezviwanikwa zvemigodhi, uye ine zvakare yakakosha kukosha kune inopindirana yekucheka maturusi pasi pemamiriro akaomarara. Iko kukanganisa kuoma kweWC-Co alloy inowedzera nekuwedzera kwecobalt zvemukati uye saizi yezviyo zve tungsten carbide. Naizvozvo, mazhinji emigodhi alloys ane coarse-grained alloys ane yakakwira cobalt yemukati.

Magnetic saturation. 

Tiye magnetic induction intensity yealloy inowedzera nekuwedzera kwekunze kwemagineti. apo iyo magnetic field intensity inosvika kune imwe kukosha, iyo magnetic induction intensity haichawedzera, kureva kuti, alloy yasvika magnetic saturation. Iyo magineti saturation kukosha kweiyo alloy inongoenderana neiyo cobalt yemukati mune alloy. Naizvozvo, iyo magineti saturation inogona kushandiswa kutarisa kusiri-kuparadza kuumbwa kweiyo alloy kana kuona kana pane isiri-magnetic η l chikamu mune alloy ine inozivikanwa kuumbwa.

Elastic modulus.

NokutiWCine yakakwira elastic modulus,so asWC-Co. Iyo elastic modulus inoderera nekuwedzera kweiyo cobalt yemukati mualloy, uye saizi yezviyo zve tungsten carbide mualloy haina mhedzisiro yakajeka pane elastic modulus.Wnekuwedzera kwekushisa kwebasa tiye elastic modulus yealloy inoderera.

Thermal kuwedzera coefficient.

Iyo mutsara yekuwedzera coefficient yeWC-Co alloy inowedzera nekuwedzera kweiyo cobalt yemukati. Nekudaro, iyo yekuwedzera coefficient yealloy yakadzikira zvakanyanya kupfuura iyo yesimbi, izvo zvinokonzeresa kudzvanya kudzvanywa kana alloy chishandiso chaiswa uye chakasungwa. Kana matanho ekutonhora anononoka akasatorwa, alloy inowanzotsemuka.

Zvese mune zvese, Tungsten carbide ine yakanyanya kuita mune yayo yemuviri zvimiro. Nekuda kweizvozvo, Tiye akakodzera emuviri zvimiro zvecemented carbide haana kuganhurirwa kuneavo. Tiye hunhu hwezvinhu zvine magadzirirwo akasiyana ekushandisa chaiwo achave akasiyana. Waida kuziva zvakawanda nezve tungsten carbide unogamuchirwa kutitevera.
