Guvura ubushyuhe bugaragara bigabanyijemo ibyiciro bibiri: imwe irimo gufata ubushyuhe bukabije no kuvura ubushyuhe, naho ubundi ni uburyo bwo kuvura imiti. Uburyo bwo gupima uburemere ni bukurikira:
1. Kugabanuka cyane no kuvura ubushyuhe
Kugabanuka cyane no gucuruza ubushyuhe mubisanzwe bikorwa no kwishyuza cyangwa gushyushya. Ibipimo nyamukuru bya tekiniki nibikomere bitagaragara, ubukana bwaho kandi ubujyakuzimu bukomeye. Vickers Hardness Tester cyangwa Rockwell Hardness Tester irashobora gukoreshwa mugupima gukomera. Imbaraga zigeragezwa Guhitamo bifitanye isano nubujyakuzimu bwibice byiza hamwe nibikomere bitagaragara byumurimo. Hano hari imashini eshatu zikomeye zirimo hano.
. Irashobora gukoresha imbaraga zigerageza 0.5-100KG kugirango ugerageze kumwanya ukomera cyane nka 0.05mm. Ukuri kwayo ni hejuru kandi birashobora gutandukanya abakozi bavuwe. Itandukaniro rito mu gukomera kugaragara, hiyongereyeho, ubujyakuzimu bw'ikigereranyo cyiza nacyo cyagaragaye na Vickers Gupima, bityo birakenewe kugirango usuzume ibizamini byo gutunganya ubushyuhe cyangwa ngo ukoreshe umubare munini w'abakozi bavurwa ubushyuhe.
. Hano hari umunzani utubiri muri rockwell yo hejuru cyane gusuzugura. Irashobora kugerageza ibikorwa bitandukanye bitarushijeho kwikomeretsa bifite ubujyakuzimu bukomeye burenze 0.1mm. Nubwo ari ukuri kwa rockpial rockness gupima ntabwo ari hejuru nkibya 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. Urutare rwinyuma rwagati rurashobora gukoreshwa muguhita no kudakurangiza ibice byabakozi bavuwe neza-bavuwe umwe. Ni ngombwa cyane gutunganya ibyuma no gutunganya imashini. Iyo kuvura ubushyuhe bukabije urwego runini cyane ni umubyimba, rocksell 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, ukwiye kwitabwaho kurangiza kandi ubunini rusange bwumurimo. Ubu buryo bwo gupima ntabwo bufite abashuka kandi bukongerera gukomera gupima ni ukuri, ariko birakwiriye gupima urubuga.
Guvura imiti
Guvura ubushyuhe bwa chemical ni ukwirukana hejuru yumurimo hamwe na atome yibintu bimwe cyangwa byinshi, kugirango uhindure imiti, imiterere n'imikorere yabanyamirimo. Nyuma yo kuzimya ubushyuhe buke burarira, kunyura mu bikorwa bifite ubukana bukabije no kwambara. Kandi ubaze imbaraga z'umubiri, kandi ishingiro ry'ukazi rifite imbaraga n'ubutori. Ibipimo nyamukuru bya tekiniki byumurimo wo kuvura imiti ni ubujyakuzimu bwibice bikomeye hamwe nubukomere butagaragara. Intera yo gukomera guta kuri 50hrc niyo ubujyakuzimu bworoshye. Ikigeragezo gikomeye cyane cyikigereranyo cya chimique yavuwemo abakozi bafashwe birasa nibigeragezo bikomeye byo kwishora mu bushyuhe bukabije buvuwe. Vickers Hardness Tosters, Rockpial Rockwell Hardness Testers cyangwa Rockwell Allisters Hardness irashobora 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, Rocksewell Gukomera Gupima birashobora gukoreshwa mugupima agaciro ka hrn
