Kev sib raug zoo ntawm hardness thiab hnav tsis kam rau tungsten carbide

Hnav tsis kam yog hais txog lub peev xwm los tiv thaiv kev sib txhuam, thiab tungsten carbide, cov khoom siv dav heev, muaj kev hnav tsis kam. Dab tsi yog qhov kev sib raug zoo ntawm hardness thiab hnav tsis kam ntawm tungsten carbide?

Feem ntau, qhov siab dua qhov hardness yog, qhov zoo dua qhov hnav tsis kam. Qhov me me ntawm cov hlau tungsten muaj, qhov siab dua qhov hardness thiab zoo dua hnav tsis kam. Kev hnav tsis kam ntawm cov cemented carbide muaj feem xyuam nrog cov khoom sib faib ntawm titanium carbide thiab cobalt carbide. Nws yuav muaj zog dua hardness thiab zoo hnav tsis kam, nrog ntau titanium carbide thiab tsawg cobalt.

Cov tungsten carbide tuaj yeem ncav cuag 86 HRA txog 94 HRA ntawm chav tsev kub, sib npaug rau 69 txog 81HRC. High hardness tuaj yeem khaws cia ntawm 900 txog 1000 ° C nrog eaxcellent hnav tsis kam. Cov cemented carbide yog tsim los ntawm ntau cov hlau refractory carbides xws li WC, TiC, NBC, thiab Vc nrog cov hmoov metallurgical txoj kev ua ib phau ntawv khi. Piv nrog rau cov khoom siv superhard, nws muaj zog toughness. Piv nrog rau high-speed steel, nws muaj zog hardness thiab hnav tsis kam.

Hardness yog ib qho tseem ceeb ntawm kev ntsuas cov khoom siv hlau, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv elastic deformation, yas deformation, thiab kev puas tsuaj. Yog tias lwm yam tseem ceeb tsis tau txiav txim siab, kev sib raug zoo ntawm hardness thiab hnav tsis kam yog qhov siab dua qhov hardness, qhov zoo dua qhov hnav tsis kam. Cov khoom siv tib yam muaj kev kho deg sib txawv, thiab lub hardness yog proportional rau hnav tsis kam.

Txawm li cas los xij, cov khoom siv nrog qhov zoo tshaj plaws hnav tsis kam yuav tsis muaj hardness siab. Piv txwv li, lub hardness ntawm cam khwb cia hlau uas yog cov khoom siv hnav-resistant tsis siab.

Lub siab hardness thiab zoo hnav tsis kam yog qhov yuav tsum tau ua. Raws li cov txheej txheem tshwj xeeb ntawm cov khoom siv carbide, ZZBETTER txais yuav cov txheej txheem HIP sintering. Thaum qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Qhov no muaj zog heev rau tungsten carbide blanks sintering thiab precisely tswj lub qhov ntev qhov tseeb ntawm cov carbide coj qhov chaw.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa mus rau US MAIL hauv qab ntawm nplooj ntawv.
