Hardness thiab Toughness ntawm Carbide Zund Cutter

Thaum nws los txog rau tungsten carbide zund cutters, toughness thiab hardness yog ob yam tseem ceeb ntawm cov cuab yeej txiav. Lub toughness thiab hardness ntawm cov ntaub ntawv hniav tuaj yeem kuaj tau los ntawm kev ntsuas tensile thiab cuam tshuam. Nws zoo nkaus li tias hardness thiab toughness yog sib tw rau ib leeg. Hauv tsab xov xwm no, cia peb tau txais cov ntaub ntawv ntau ntxiv txog hardness thiab toughness.

HARDNESS yog dab tsi?

Hardness yog ib qho kev ntsuas ntawm qhov tsis kam mus rau cov yas deformation hauv zos uas tshwm sim los ntawm cov neeg kho tshuab indentation lossis puas. Tungsten carbide zund cutters yog ua los ntawm cov khoom zoo tungsten carbide hmoov thiab cov hmoov nplej, xws li cobalt, npib tsib xee, thiab hlau. Tungsten carbide yog ib hom kev lag luam nto moo raw khoom, uas tuaj yeem nyuaj dua li cov khoom siv niaj hnub no.

Ntau qhov kev ntsuam xyuas tuaj yeem siv los ntsuas cov khoom siv tawv, xws li Rockwell Test, Brinell Test, Vickers Test, Knoop Test, thiab lwm yam.

Cov ntaub ntawv nyuaj tuaj yeem tiv taus deformation zoo dua li cov ntaub ntawv softer yog li lawv siv rau kev txiav, sawing, shearing, thiab chopping. Thaum lub sij hawm ua hauj lwm, txawm tias thaum txiav cov khoom nyuaj, tungsten carbide zund cutters tseem khaws cov duab thiab khaws cia.

Nws tsis muaj qhov tsis ntseeg tias cov khoom siv tawv tawv muaj ntau qhov zoo dua cov ntaub ntawv softer, tab sis lawv kuj muaj qee qhov tsis zoo, vim tias lawv tuaj yeem ua rau nkig thiab ua rau qaug zog, ua rau tawg thaum ua haujlwm.

TUGHNESS yog dab tsi?

Toughness yog lub peev xwm ntawm cov khoom siv los nqus lub zog thiab plastically deform yam tsis muaj kev tawg. Toughness yog lub zog uas cov khoom tiv thaiv rupture. Rau cov cuab yeej txiav, txaus toughness yog qhov tseem ceeb. Lub lim tiam dhau los peb tau txais video los ntawm peb cov neeg siv khoom. Nws muaj ob hom tungsten carbide cutters, ib qho yooj yim tawg, thiab lwm yam tsis yog. Qhov no yog hais txog toughness. Cov tungsten carbide cutters nrog ntau dua toughness yog yooj yim dua tawg, thaum lub cutters nrog qis toughness yog nyuaj.

Thaum tib neeg tau txais tungsten carbide cutters, lawv xav nrhiav ib qho nrog ob qho tib si siab hardness thiab toughness. Txawm li cas los xij, tungsten carbide cutters hauv kev muaj tiag yog qhov nyuaj heev tab sis tsis tshua muaj zog, lossis tawv heev, tab sis tsis nyuaj heev. Txhawm rau hloov qhov xwm txheej no, peb tuaj yeem ntxiv qee cov ntaub ntawv hybrid hauv nws, xws li carbon fiber, uas yog hloov tau yooj yim dua thiab ruaj khov dua li cov khoom loj ntawm cov pa roj carbon ib leeg.

Yog tias koj txaus siab rau tungsten carbide cutters thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa ntawv xa mus rau hauv qab ntawm nplooj ntawv.
