Tsanangudzo Yakadzama yeKushandura Kuoma Kwezvinhu

Material Hardness ndechimwe chezviratidzo zvakakosha zvinoshandiswa kuongorora kuramba kwechinhu kune deformation, kupfeka, uye abrasion. Zvakajairwa kuomarara zviyero zvinosanganisira Vickers Hardness (HV), Brinell Hardness (HB), uye Rockwell Hardness (HRC). Kufambisa kutendeuka kweMaterial Hardness values ​​pasi pezviyero zvakasiyana, zvakakosha kuti unzwisise maitiro ekushandura akakodzera uye matafura ereferenzi anoshanda.

Muedzo wekuoma kwezvinhu

Yakajairika HV-HB-HRC Shanduko Tafura

Pazasi pane tafura yereferensi inopfupikisa huwandu hwehuwandu hweHV, HB, uye HRC yakavakirwa pakuyedza data uye zvakajairwa zvakatemwa:

Cherechedza: Iwo ari pamusoro apa maitiro anogona kusiyana zvishoma zvichienderana nemhando yezvinhu uye mamiriro ekuyedzwa.

Shanduko formula pakati peHV-HB-HRC

Iko kutendeuka pakati peakasiyana Material Hardness zviyero (HV, HB, HRC) haina formula chaiyo, sezvavanobva pane dzakasiyana nzira dzekuedza uye misimboti. Zvisinei, ivo vanogona kazhinji kufungidzirwa vachishandisa epirical formula uye matafura ekushandura. Heano mamwe akajairika hukama hwekushandura pakati pekuomarara zviyero:

1. Shanduko pakati peHV (Vickers Kuoma) uye hb (Brinell Hardness)

Zvezvinhu zvakaita sesimbi, anotevera empirical formula anowanzo shandiswa pakushandura:

HB=0.927×HVHB = 0.927 \nguva HV HV=1.15×HBHV = 1.15 \nguva HB

2. Shanduko pakati peHV (Vickers Kuoma) uye HRC (Rockwell Hardness C Scale)

Zvezvinhu zvakaita sesimbi, iyo inotevera fomula inowanzoshandiswa pakushandura:

HRC=0.0023×HV−1.9HRC = 0.0023 \nguva HV - 1.9

Neimwe nzira, Material Hardness kutendeuka matafura anowanzoshandiswa, kunyanya kune zvinhu zvine huwandu hwekuoma kwakakura.

3. Shanduko pakati peHB (Brinell Hardness) uye HRC (Rockwell Hardness C Scale)

Dzimwe nguva, iyo inotevera fomula inogona kushandiswa kufungidzira kutendeuka:

HRC=0.002×HB−1.2HRC = 0.002 \nguva HB - 1.2

Notes

• Aya mafomula ekushandura anoshanda kune zvakajairwa zvinhu zvakaita sesimbi. Zvezvinhu zvakasiyana, kunyanya asiri simbi, kushanduka kwekuoma kunogona kusiyana.
• Mafomura anopa maitiro akaenzana; iyo chaiyo yakaoma kutendeuka inokonzerwawo nezvinhu zvakadai sekuumbwa kwezvinhu, microstructure, uye kupisa kurapwa mamiriro.
• Iyo yakanyanya kuomarara shanduko inowanzoitwa uchishandisa data yekuyedza kana kuomarara matafura ekushandura, kunyanya kana nzira dzakasiyana dzekuyera kuomarara dzichishandiswa.

Mhedziso

Kunzwisisa hukama hwekushandura uye kuverenga kwehuwandu hwekuoma kwezvinhu kwakakosha pakutonga kwemhando uye kusarudzwa kwezvinhu muindasitiri yemazuva ano.. Yakarurama Material Hardness kukosha mareferensi uye kuverenga kunogona kuvandudza kuvimbika kwechigadzirwa uye kukwidziridza mitengo. Kana zvakakodzera, mamwe matafura ereferenzi akagadziridzwa anogona kugadzirwa zvichibva pane chaiyo zvinhu uye yekuyedza setups.
