Qaphela:
1. Ubulukhuni be-Brinell: Isetshenziselwa ikakhulukazi ukukala ubulukhuni bokukhokhiswa, ukuthethelelwa, izingxenye zensimbi ezingezinhle, amabhilithi asongwe afudumele nezingxenye eziveziwe. Uhla lokulinganisa luyi-≥450.
2. I-HRADELWELWER HUNDNESS: I-HRA isetshenziselwa ikakhulukazi ama-hardness ama-hardness ama-hardness ukukala ubulukhuni bezinto zokwakha kanye nokuqina okuphezulu kakhulu kune-HRC67, njenge-carbide eyenziwe ngesibili, njenge-carbide ehlanganisiwe, i-carride ephakeme, i-njll. Uhla lokulinganisa lunguHra> 70. I-HRC isetshenziselwa ikakhulukazi ukukala ubulukhuni bezingxenye zensimbi (njengensimbi yekhabhoni, insimbi yethuluzi, i-alloy yensimbi, njll.) Ngemuva kokucimana noma ukulangazelela. Uhla lokulinganisa yi-HRC20 ~ 67.
3. Ubulukhuni bama-Vicklers: Kusetshenziselwa ukukala ubulukhuni bezingxenye ezincanyana nezingxenye zensimbi yensimbi, futhi kungasetshenziswa futhi ukukala ubulukhuni bezingxenye ezilukhuni ezingaphezulu njenge-carburshing, i-claninging, kanye ne-nitriding.
