Yuav Ua Li Cas Txheeb Xyuas Qhov Hardness thiab Wear Resistance ntawm Cov Hniav Hniav

Kev tawv thiab tsis yooj yim hnav Qhov tawv yog qhov tseem ceeb uas cov khoom siv hniav hniav yuav tsum muaj. Txhawm rau tshem tawm cov chips ntawm ib qho workpiece, ib tug hniav serrated yuav tsum tawv dua li cov khoom siv workpiece. Qhov tawv ntawm ntug txiav ntawm cov hniav hniav siv rau kev txiav hlau feem ntau yog siab dua 60hrc, thiab qhov tsis yooj yim hnav yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev hnav. Feem ntau, cov khoom siv hniav hniav tawv dua, nws qhov kev tiv thaiv kev hnav zoo dua.

Qhov siab dua qhov nyuaj ntawm cov chaw nyuaj hauv lub koom haum, ntau tus lej, cov khoom me me, thiab qhov sib npaug ntau dua qhov kev faib tawm, qhov zoo dua qhov hnav tsis kam. Kev hnav tsis kam kuj tseem cuam tshuam nrog cov tshuaj lom neeg sib xyaw, lub zog, microstructure thiab qhov kub ntawm thaj chaw sib txhuam ntawm cov khoom.

Lub zog thiab kev tawv txaus Txhawm rau kom cov hniav hniav tiv taus qhov siab dua thiab ua haujlwm nyob rau hauv qhov kev poob siab thiab kev co uas feem ntau tshwm sim thaum lub sijhawm txiav yam tsis muaj chipping thiab tawg, cov khoom siv ntawm cov hniav tshuab yuav tsum muaj lub zog thiab kev tawv txaus. Kev tiv taus kub siab Kev tiv taus kub yog qhov qhia tseem ceeb los ntsuas qhov kev ua tau zoo ntawm cov khoom siv ntxig hniav.
Nws yog hais txog kev ua tau zoo ntawm cov khoom siv hniav hniav kom tswj tau qhov nyuaj, hnav tsis kam, lub zog thiab kev tawv nyob rau hauv qhov kub siab. Cov khoom siv hniav hniav zoo li yuav tsum muaj peev xwm tsis raug oxidized ntawm qhov kub siab thiab zoo tiv thaiv kev nplaum thiab tiv thaiv kev sib kis, uas yog, cov khoom siv yuav tsum muaj kev ruaj khov tshuaj zoo.

Cov khoom zoo ntawm lub cev thermal thiab kev tiv thaiv thermal shock Qhov zoo dua ntawm cov khoom siv hniav hniav, qhov yooj yim dua rau qhov kub txiav kom dissipate los ntawm thaj chaw txiav, uas yog qhov zoo rau kev txo qhov kub txiav.
