Chithandizo chapamwamba kutentha chimagawidwa m'magulu awiri: imodzi imakhala yotopetsa komanso yotentha kutentha kutentha, ndipo inayo ndi mankhwala kutentha kwa mankhwala. Njira yoyesera yoyeserera ndi motere:
1.
Kutalika kopitilira muyeso komanso kusanza kutentha nthawi zambiri kumachitika ndi kuwotcha kotentha kapena lawi. Magawo apamwamba aluso ndi kuvuta kwambiri, kuuma kwanuko komanso kumagwira ntchito mozama kwambiri. Ma vackers hardness tester kapena woyeserera wolimba mtima amatha kugwiritsidwa ntchito poyesa kuwuma. Kuyesa Kusankha Kusankhidwa kumakhudzana ndi kuya kwa kuya kwa okhazikika komanso kuuma kochuluka kwa ntchito. Pali makina atatu olimbana apa.
. Itha kugwiritsa ntchito mphamvu yoyesera ya 0,5-100kg kuti iyesere zolimba zolimba ngati 0,05mmm yayikulu. Kulondola kwake kumakhala kokwera ndipo kumatha kusiyanitsa makona ogwiritsira ntchito kutentha. Kusiyana pang'ono pokhalitsa, kuphatikiza apo, kuya kwa mphamvu yolimba kumaonedwanso ndi ma neckers kulimbikirana kwa mayunitsi omwe amasintha njira zopangira chithandizo chamankhwala.
. Pali masikelo atatu a Yesterial Centernerness Hasder kuti asankhe kuchokera. Imatha kuyesa zojambula zolimba kwambiri zomwe zomwe zimapangitsa kuti zikuluzikulu zowoneka bwino zimaposa 0.1mm. Ngakhale kulondola kwa woyeserera wa Crifies Rock Connerland sikukwera kwambiri monga momwe ma vackers kulimbikirana, amatha kukwaniritsa zofunika kale ngati njira yoyang'anira chithandizo chamankhwala. .Bsides, imakhalanso ndi machitidwe ochita opaleshoni, kugwiritsa ntchito mosavuta, mtengo wotsika mtengo, muyeso wachangu, komanso kuwerenga mwachindunji mfundo zolimba. Woyang'anira mphamvu zapamwamba kwambiri amatha kugwiritsidwa ntchito pozindikira mwachangu komanso osakhala osungunuka kwambiri. Ndizofunikira kwambiri pakukonzekera zitsulo ndi makina opanga mafakitale. Pamene kutentha kwa kutentha kwa kutentha ndi kotchinga, tester yolimba imatha kugwiritsidwanso ntchito. Pamene kutentha kwa kutentha kwabwino kusanjikiza ndi 0,4-0.8mm, kukula kwa HRA kungagwiritsidwe ntchito. Kuzama kwa ulusi wouma pomwe umapitilira 0,8mm, kukula kwa HRC kungagwiritsidwe ntchito. Vickers, Rockwerth ndi Surnard Rominal Makhalidwe oyendayenda mosavuta akhoza kusinthidwa mosavuta, zojambula kapena mikhalidwe yolumikizira yofunikira ndi ogwiritsa ntchito apadziko lonse lapansi. American Interm ndi Standar Standard GB / T yaperekedwa.
. Mukayeza, chidwi chiyenera kulipidwa pamapeto chapamwamba komanso makulidwe onse ophatikizika. Njira yoyesererayi ilibe phockers ndipo oyendetsa zolimbitsa thupi ndi olondola, koma ndizoyenera muyeso wamasamba mufakitale.
2 mankhwala kutentha kwa mankhwala
Kutentha kwa mankhwala ndikuthirira kwambiri ntchito zomwe zili ndi maatomu amodzi kapena angapo akusintha kapangidwe kake, kapangidwe ndi ntchito zantchito yogwira ntchito. Pambuyo pakuthamangira komanso kutentha pang'ono kutentha, kuchuluka kwa ntchitoyo kumakhala ndi kuuma kwambiri komanso kuvala kukana. Ndipo kulumikizana ndi kutopa, ndipo maziko a ntchitoyo ali ndi mphamvu yayikulu komanso kuuma. Magawo apamwamba aluso a mankhwala kutentha kutentha kwa mankhwala ndi kuya kwa mphamvu yolimba ndi kuuma kochuluka. Mtunda womwe kuuma kumatsikira mpaka 50hrc ndiye wogwira ntchito mozama. Kuyesedwa kwamphamvu kwambiri kwa kutentha kwamitundu kumafanana ndi kuyesedwa kwamphamvu kwa kutentha kopitilira muyeso kuchitidwa zomangamanga. Makonda a VICS Hardes, ntchentche a rockiorder Haxtness testers kapena ma tarder Hardness amatha kugwiritsidwa ntchito. Kupanga kolimba kuti mudziwe, kokha makulidwe a nitricker okha ndiocheperako, osaposa 0.7mm, ndiye
3.. Chithandizo cha kutentha
Ngati magawo othandizira kutentha amafunikira kuvuta kwa kutentha kwambiri, magawo owuma kwambiri amachitika pogwiritsa ntchito njira yotenthetsera, etc. Kuyeserera kwapadera kwa zojambulazo, ndipo kuyesedwa kolimba kumayenera kugwiritsa ntchito testicle yolimba kuti ayesere mtengo wa HRC. Ngati kutentha kwa kutentha kosanjikiza ndi kosafunikira, woyeserera wamphamvu wa Borfic Bory uge angagwiritsidwe ntchito kuyesa mtengo wa HRN
