Kuvura ubushyuhe bugabanijwemo ibyiciro bibiri: imwe ni ubushyuhe bwo hejuru no kuvura ubushyuhe, kandi ikindi nivura ubushyuhe bwa shimi. Uburyo bwo gupima uburemere ni bukurikira:
1. Kugabanuka hejuru no kuvura ubushyuhe
Ubuso bumaze no kuvura ubushyuhe busanzwe bukorwa no kwishyuza cyangwa gushyushya. Ibipimo nyamukuru bya tekiniki ni ugukomera, gukomera kwaho hamwe nubujyakuzimu bukomeye. Vickers Hardness Tester cyangwa Rockwell Hardness Tester irashobora gukoreshwa mugupima gukomera. Imbaraga zigeragezwa Guhitamo bifitanye isano nubujyakuzimu bwibice byiza hamwe nubuso bwakazi. Hano hari imashini eshatu zikomeye zirimo hano.
. Irashobora gukoresha imbaraga za 0.5-100KG kugirango ugerageze ubuso bunini cyane nka 0.05mm. Ukuri kwayo ni hejuru kandi birashobora gutandukanya abakozi bavuwe. Itandukaniro rito ryo gukomera ku busa, hiyongereyeho, ubujyakuzimu bw'ibice bikomeye bifatwa na vickers gukomera, bityo birakenewe kugira ngo bisuzume ibizamini byo gutunganya ibintu byo kuvura cyangwa gukoresha umubare munini wo kuvura ubushyuhe bwinshi.
. Hano hari umunzani eshatu kuri rockwell gukomera gusuzugura. Irashobora kugerageza ibintu bitandukanye bigoramye ibikorwa bifite ubujyakuzimu bukomeye burenze 0.1mm. Nubwo ari ukuri kwubuso bwa rockwell testness ntabwo ari hejuru nkubwa vickers gukomera, birashobora kubahiriza ibisabwa nkuburyo bwo kumenya ubuziranenge. .Bisi, ifite kandi ibiranga imikorere yoroshye, gukoresha byoroshye, igiciro gito, gupima vuba, no gusoma neza agaciro. Ubuso bwa rockwell gukomera testers birashobora gukoreshwa muguhita kandi bidahwitse gutahura ibyiciro-bivurwa-gutwarwa nubutegetsi bumwe bwuzuye. Ni ngombwa cyane gutunganya ibyuma no gutunganya imashini. Iyo kuvuza ubushyuhe bukomeye igice kinini, Rockwell Gupima nabyo birashobora gukoreshwa. Iyo ubushyuhe bukomeye bukomeye bunini ni 0.4-0.8mm, igipimo cya HRA kirashobora gukoreshwa. Iyo ubujyakuzimu bwimbitse iyo burenze 0,8mm, igipimo cya HRC kirashobora gukoreshwa. Vickers, Rocwell na Forwintailial Gukomera Hardness Ibipimo ngenderwaho birashobora guhinduka byoroshye, byahinduwe byoroshye, ibishushanyo cyangwa indangagaciro zijyanye na porogaramu, hamwe nimbonerahamwe ikubiyemo iri murwego mpuzamahanga rwibanze ari mumahanga asanzwe yinyongera. ASTM isanzwe y'Abanyamerika n'Igishinwa gisanzwe GB / T yahawe.
. Mugihe upima, kwitondera bigomba kwishyurwa hejuru no hejuru yumubumbe rusange wakazi. Ubu buryo bwo gupima ntabwo bufite abashuka kandi bukongerera gukomera gupima ni ukuri, ariko birakwiriye gupima urubuga.
2. Guvura imiti
Guvura ubushyuhe bwa chimique ni ugukangiriza ubuso bwakazi hamwe na atome yibintu bimwe cyangwa byinshi, bityo bihindura imiti, imiterere n'imikorere yubuso bwakazi. Nyuma yo kuzimya ubushyuhe buke burarira, ubuso bwakazi bufite ubukana buhenze kandi bwambara. Kandi ubaze imbaraga z'umubiri, kandi ishingiro ry'ukazi rifite imbaraga n'ubutori. Ibipimo nyamukuru bya tekiniki byibikorwa byo kuvura imiti ni ubwimbitse bwimbibi zinangiye nubuso bwakomeretse. Intera yo gukomera guta kuri 50hrc niyo ubujyakuzimu bworoshye. Ikizamini cyo hejuru cyo gukomera kwinshi c'imiti yavukiyemo abakozi bafatwa nkibigeragezo bikomeye byo hejuru yubutaka buvuwe. Vickers Hardness Tosters, hejuru ya rockwell gukomera testers cyangwa Rockwell Allisters Gupima birashobora gukoreshwa. Gukomera gukomera, gusa umubyimba wa Nitripipipidite ubyimbye, muri rusange ntabwo urenze 0,7mm, hanyuma urutare rukomeye rwaka ntigishobora gukoreshwa
3. Kuvura ubushyuhe bwaho
Niba ibice byubuvuzi byaho bisaba gukomera kwinshi, kuvura ubushyuhe bwibanze birashobora gukorwa hakoreshejwe ubushyuhe bwo kwivuza hamwe nigikoresho gikomeye cyo gupima ubushyuhe bwo gushushanya no gupima. Niba kuvura ubushyuhe bukomantaye ni bike, hejuru ya rockwell gukomera tester irashobora gukoreshwa mugupima agaciro ka hrn.
