Nigute wahitamo testers ikomeye kugirango ugerageze ingero zitwikire?

1) Ikizamini gikomeye cya rocknell gishobora gukoreshwa mugupima gukomera kurukuta rwibyuma?

Ibikoresho byo kwipimisha ni sa-213m t22 hamwe na diameter yo hanze ya 16mm nubwinshi bwa 1,65mm. Ibisubizo by'ibizamini by'ibizamini bikomeye bya rockwell ni ibi bikurikira: Nyuma yo gukuraho igipimo cya oxide hamwe nigikorwa cya disconation hamwe na sctionber and sclesebell gukomera hejuru yumutwaro wo hanze hamwe numutwaro wa 980.7n. Nyuma yikizamini, irashobora kugaragara ko urukuta rw'ibyuma rufite uburyo buke, kandi ibisubizo nuko nyakubahwa agaciro gupimwa ari hasi cyane, bikavamo ikizamini kitemewe.

Nk'uko GB / T 230.1-2018 «Ibikoresho by'ibyuma bya Rockwell Hardness Ikizamini Igice cya 1: Uburyo bw'ikizamini», Hasi ya RockWell ni 80hrbw kandi umubyimba muto w'icyitegererezo ni 1.5mm. Ubunini bw'icyitegererezo No 1 ni 1.65mm, ubugari bw'ikigereranyo cy'imyambaro ni 0.15 ~ 0,30m, n'ubunini bw'icyitegererezo nyuma yo gukuraho urwego ruto rwerekanwe muri GB / T 230.1-2018. Mugihe cyikizamini, kubera ko nta nkunga iri hagati yicyitegererezo, bizatera uburyo buke (bushobora kubahirizwa nijisho ryambaye ubusa), bityo rero nyakwigendera gukomera hasi ni hasi.

2) Nigute wahitamo hejuru yo gupima imiyoboro yibyuma:

Nyuma y'ibigeragezo byinshi hejuru yubuso bwimiyoboro yibyuma, Isosiyete yacu yageze kumyanzuro ikurikira:

1. Mugihe ukora hejuru ya rockwell ikizamini cyangwa gukomera gukomera ku muyoboro woroheje wicyuma, inkunga idahagije y'urukuta ruzatera impengamiro kandi iganisha ku bisubizo by'ibizamini bike;

2. Niba inkunga ya silindrike yongeyeho hagati yumuyoboro ukikijwe, ibisubizo byikizamini bizacika intege kuberako umuyoboro wigituba udashobora gushingwa hejuru yumuyoboro wo hanze winyamanswa yinyuma hamwe ninkunga ya silindrike.

3. Uburyo bwo guhindura abapimisha gupimwa gukomera kuri Rocwell Hardness nyuma yo gutsemba no gusomana icyitegererezo cy'icyuma ni ukuri.

4. Nyuma yo gukuraho igipimo cya oxide hamwe nigipimo cyimiyoboro hejuru yicyuzi cyicyuma kandi imashini yikizamini hejuru yubuso hanyuma itwika, hejuru ya rockwell ihindurwa gukomera gukomeye, bisa nkaho.
