Kuyesedwa kwamphamvu kokhazikika ndi kukwiya makamaka kumagwiritsanso ntchito mphamvu zolimbitsa thupi za HRC. Ngati zinthuzo ndi zochepa komanso HRC Scale siyabwino, sikelo ya HRA ikhoza kugwiritsidwa ntchito m'malo mwake. Ngati nkhaniyo ndi yocheperako, yolimbana kwambiri ndi HR15N, HR30N, kapena HR45N ingagwiritsidwe ntchito.

Kupanga mafakitale, nthawi zina pachimake pa ntchitoyi kumafunikira kuti mukhale ndi vuto labwino, pomwepa pomwepa zimafunikiranso kuti mukhale ndi kulimbika kwambiri komanso kuvala kukana. Pankhaniyi, kuwonjezereka pafupipafupi, katemera wamakamwa, nitring, carboitrination komanso njira zina zimagwiritsidwa ntchito kunyamula chithandizo chovuta pa ntchito yogwira ntchito. Makulidwe a mawonekedwe owuma kwambiri nthawi zambiri amakhala pakati pa mamilimita ochepa ndi milimita ochepa. Za zida zokhala ndi madigiri othamanga, masikelo a HRC angagwiritsidwe ntchito kuyesa kuuma kwawo. Kwa maselo autali owumitsa minyewa, masikelo a HRD kapena HRA angagwiritsidwe ntchito. Kwa zigawo zowonda kwambiri, zolimbana zakumaso za HR15N, HR30n, ndi HR45N ziyenera kugwiritsidwa ntchito. Kwa owonda kwambiri owuma, ma vickers a micro harness tester kapena opanga ma gentrasonic hartester ayenera kugwiritsidwa ntchito.
3.. Zitsulo zowoneka bwino, zitsulo zokhazikika, zitsulo zofatsa
Zipangizo zambiri zachitsulo zimapangidwa mu boma lopaka kapena labwino, ndipo mbale zina zachitsulo zimaphatikizidwa malinga ndi madigiriyi osiyanasiyana. Kuyesa kwamitundu yovuta nthawi zambiri kumagwiritsa ntchito masikelo a HRB, ndipo nthawi zina masikelo a HRF amagwiritsidwanso ntchito kwa ofewetsa ndi kuwonda. Pampunga zoonda, zolimbana zolimbana ndi HR15T, HR30t, ndi masikelo a HR45T ziyenera kugwiritsidwa ntchito.
4. Chitsulo chosapanga dzimbiri
Zinthu zachitsulo zosapanga dzimbiri nthawi zambiri zimaperekedwa m'maiko oterowo monga maluso, kupsa mtima, kusuntha, yankho lolimba. Miyezo ya National imatchulanso zomwe zikugwirizana ndi zowoneka bwino, ndipo kuyezetsa kolimba kumagwiritsira ntchito zolimbitsa thupi za RRC kapena HRB. Mbali ya HRB idzagwiritsidwa ntchito ngati chitsulo chosakhazikika cha austetitic ndi chilengedwe cha HRC cha woyeserera wowongolera lidzagwiritsidwa ntchito ngati chitsulo chosapanga dzimbiri kapena ma sheet ochepera 1 ~ 2mm.

Kuyesa kwa Brinell kulimba kumagwiritsidwa ntchito ngati chitsulo chopangidwa, chifukwa ma microstructuctuctuctuction a chitsulo chomwe adapanga si yunifolomu zokwanira, ndipo brinoll hardination yoyeserera ndi yayikulu. Chifukwa chake, kuyesa kwa Brinoll kulimba kumatha kuwonetsa zotsatira zonse za micrestraction ndi katundu wa mbali zonse za zinthuzo.
6. Tsitsani chitsulo
Zida zachitsulo nthawi zambiri zimadziwika ndi kapangidwe kake ndi mbewu zochulukirapo, motero brinyoll hardness kuyezetsa kumakhazikitsidwa. Woyesa wolimba mtima amatha kugwiritsidwa ntchito poyesa kuwuma kwa ena. Komwe kulibe malo okwanira pagawo laling'ono la tirigu wabwino wa Brinell Harness Herness, koma ndibwino kugwiritsa ntchito kuchuluka kwa HRE kapena HRK.
Zida zolimba zolimba zimagwiritsa ntchito zolimbitsa thupi zolimbitsa thupi za RRC. Ngati zinthuzo ndizosagwirizana, zingapo zomwe zimayesedwa ndi mtengo wapakati.

Kuyesa kwamphamvu kwa zinthu zovuta zomwe zimangogwiritsa ntchito mawonekedwe okhazikika a Hra.
