Kev kuaj cov tawv ntawm cov khoom siv hlau

Lub Zogxeemntawm cov ntaub ntawv hlau

Hnyav nyuaj yog qhov peev xwm ntawm cov khoom siv los tawm tsam qhov deformation hauv cheeb tsam, tshwj xeeb tshaj yog yas deformation, kos duab, lossis khawb. Nws yog ntsuas ntawm qhov muag thiab tawv tawv ntawm cov ntaub ntawv.
Hardness tau muab faib ua peb hom raws li txoj kev kuaj sib txawv.
(1) khawb qhov tawv tawv. Nws yog tsuas yog siv los piv rau cov tawv thiab muag ntawm cov ntxhia sib txawv. Cov qauv yog xaiv cov pas nrog ib qho kawg thiab ib qho muag muag. Cov khoom siv ntsuas yuav raug khawb raws li tus pas, thiab qhov nyuaj thiab qhov muag ntawm cov khoom raug ntsuas yuav raug txiav txim siab raws li txoj hauj lwm kos. Cov khoom muaj txiaj ntsig, cov khoom nyuaj ua rau khawb ntev, cov khoom muag mos ua rau khawb luv.
Nias hardness. Nws yog tsuas yog siv rau cov ntaub ntawv hlau. Cov txheej txheem yog mus nias lub taub hau tshwj xeeb rau hauv cov khoom siv kuaj nrog qee qhov sib txawv, thiab sib piv cov khoom tawv los ntawm cov khoom siv kuaj nrog qhov loj ntawm cov yas hauv zos deformation ntawm cov khoom siv. Vim tias qhov sib txawv ntawm lub taub hau indentation, lub sijhawm tha thiab lub sijhawm ntev, muaj ntau yam ntawm indentation hardness, mas Brinell hardness, Rockwell hardness, Vickers hardness thiab micro-hardness.
(3) thim rov qab hardness. Feem ntau siv rau cov khoom siv hlau, txoj kev ua los ua ib qho tshwj xeeb me me rauj los ntawm qee qhov siab pub dawb lub caij nplooj zeeg qhov cuam tshuam ntawm cov qauv ntawm cov khoom siv los ntsuas, thiab cov nyiaj ntawm lub zog lub zog khaws cia (thiab tom qab ntawd tso tawm) hauv cov txheej txheem ntawm cuam tshuam ntawm tus qauv (txiav txim siab los ntawm bounce qhov siab ntawm lub tsev me me) los txiav txim siab qhov nyuaj ntawm cov khoom.
