1.Rockwell Knoop Vickers uburyo bwo gupima ubukana bwa aluminium nitride ceramics
Kubera ko ibikoresho bya ceramic bifite imiterere igoye, birakomeye kandi byoroshye muri kamere, kandi bifite imiterere ya plastike ntoya, uburyo bukoreshwa muburyo bwo kwerekana ubukana burimo ubukana bwa Vickers, gukomera kwa Knoop no gukomera kwa Rockwell. Isosiyete ya Shancai ifite ibizamini bitandukanye byo gupima ubukana, hamwe n'ibizamini bitandukanye byo gukomera hamwe n'ibizamini bitandukanye bifitanye isano.
Ibipimo bikurikira birashobora gukoreshwa nkibisobanuro:
GB / T 230.2 Ibikoresho Byuma Ikizamini gikomeye cya Rockwell:
Hariho umunzani mwinshi wa Rockwell, nibikoresho bya ceramic muri rusange bikoresha umunzani wa HRA cyangwa HRC.
GB / T 4340.1-1999 Metal Vickers ikizamini gikomeye hamwe na GB / T 18449.1-2001 Ikizamini gikomeye cya Metal Knoop.
Uburyo bwo gupima Knoop na Micro-Vickers mubusanzwe ni bumwe, itandukaniro ni indenters zitandukanye zikoreshwa.
Birakwiye ko tumenya ko kubera imiterere yihariye yibicuruzwa, dushobora kuvanaho indangagaciro za Vickers zitemewe ukurikije uko indentation ihagaze mugihe cyo gupima kugirango tubone amakuru yukuri.
2.Uburyo bwo gupima ibyuma bizunguruka
Ukurikije uburyo bwo gupima ubukana bwibyuma hamwe nicyuma kitagira ibyuma byerekanwe muri JB / T7361-2007, hariho uburyo bwinshi bwo kwipimisha ukurikije gahunda yakazi, byose birashobora kugeragezwa hamwe nugupima ubukana bwa Shancai:
1 method Uburyo bwo gupima ubukana bwa Vickers
Mubisanzwe, hejuru yikomye ibice bigeragezwa nuburyo bwo gupima ubukana bwa Vickers. Hagomba kwitonderwa hejuru yo kurangiza akazi no gutoranya imbaraga zipimisha.
2 method Uburyo bwo gupima ubukana bwa Rockwell
Ibizamini byinshi bya Rockwell bikozwe hakoreshejwe igipimo cya HRC. Shancai Rockwell igerageza ikusanya uburambe bwimyaka 15 kandi irashobora guhaza ibikenewe byose.
3 method Uburyo bwo gupima ubukana bwa Leeb
Ikizamini cya Leeb gishobora gukoreshwa mubitereko byashyizweho cyangwa bigoye gusenya. Ibipimo byayo neza ntabwo ari byiza nkibipimo byo gupima intebe.
Ibipimo ngenderwaho bikoreshwa cyane cyane mugupima ubukana bwibice bifata ibyuma, ibice bifatanye kandi bifite ubushyuhe hamwe nibice byarangiye hamwe nibice bitwara ibyuma bidafite fer.
