I. Kuomarara kweRockwell (HR)
Dzvanya pano kuti uwane rumwe ruzivo nezvezvigadzirwa zvedu.
1. Nheyo

Uchishandisa koni yedhaimani (ine kona yepamusoro ye120°) kana bhora resimbi (rine dhayamita ye1.59mm kana 3.18mm) sechinopinzwa, dzvanya pamusoro pechinhu pasi pebasa rekutanga nemutoro mukuru. Kukosha kwekuoma kunoverengerwa zvichibva pahudzamu hwekuoma—kuoma kwakadzika, ndiko kudzikira kwekuoma.

2. Hunhu

- Kumhanya kwekuyedza nekukurumidza uye kushanda kuri nyore, kwakakodzera kuyedza kwebatch.
- Inokwanisa kuyedza zvinhu zvekuoma kwepakati kusvika kwakanyanya.
- Zviyero zvakawanda zviripo zvichibva pakuoma kwezvinhu:
- HRA: Inoshandisa mutoro unorema 60kg uye dhaimani inomira, yakakodzera zvinhu zvakaoma zvakanyanya zvakaita semacarbide akagadzirwa nesimende.
- HRB: Inoshandisa mutoro unorema 100kg uye chinhu chinovhara bhora resimbi, chakakodzera simbi yakapfava, alloys dzemhangura, alloys dzearuminiyamu, nezvimwewo.
- HRC: Inoshandisa mutoro unorema 150kg uye dhaimani inomira, yakakodzera simbi yakadzima, alloys dzakaomarara, nezvimwewo.

3. Mashandisirwo Akajairika

Inoshandiswa zvakanyanya pakuedza nekukasika kuomarara kwezvinhu zvesimbi zvakaita sezvishandiso zvekucheka, mabheyaringi, magiya, uye zvikamu zvesimbi zvakakandwa.

II. Kuomarara kweBrinell (HBW)

1. Nheyo

Bhora rakaoma re alloy rine dhayamita yakati (kazhinji 10mm) rinodzvanywa pamusoro pechinhu pasi pemutoro wakatarwa, uye kukosha kwekuoma kunoverengerwa zvichibva padhayamita yekudzika.
Mhando dzakajairika dzeBrinell Hardness:

- HBS: Inoshandisa simbi inopinza bhora, yakakodzera zvinhu zvine kuomarara ≤ 450 HB, zvakaita sesimbi yakapfava, simbi yakakandwa yegrey, uye simbi dzisina ferrous.
- HBW: Inoshandisa bhora rakasimba, rakakodzera zvinhu zvine kuomarara ≤ 650 HB, uye ndiyo nzira huru yemazuva ano.

2. Hunhu

- Mhedzisiro yakagadzikana uye inodzokororwa zvakanaka.
- Yakakodzera simbi dzakapfava kusvika pakati nepakati dzakaoma.
- Kupinda mukati kwakakura, saka hakuna kukodzera zvikamu zvine madziro matete kana zvidiki.

3. Mashandisirwo Akajairika

Kuyedzwa kwekuoma kwezvinhu zvakagadzirwa uye zvikamu zvakagadziriswa zvisina kusimba, zvakaita sesimbi yakanyungudutswa, simbi yakakandwa, uye simbi dzisina feri pamwe chete nesimbi dzadzo.

III. Kuomarara kweVickers (HV)

1. Nheyo

Chidimbu chedhaimani chepiramidhi ine kona ye136° apex chinoshandiswa kudzvanya pamusoro pechinhu pasi pemutoro wakatarwa, uye kukosha kwekuoma kunoverengerwa zvichienderana nehurefu hwechidimbu.

2. Hunhu

- Kunyatsojeka: Kunogonesa kuyera kuomarara kwakarurama, kunyangwe munzvimbo diki kwazvo (semuenzaniso, nharaunda diki dzezvinhu).
- Kushandiswa kwakafara: Kwakakodzera zvinhu zvekuyedza zvakasiyana-siyana, kubva kusimbi dzakapfava (senge alloys dzealuminium) kusvika kune zvinhu zvakaoma zvakanyanya (senge makabhohaidhiretsi akasimwa).
- Kudzika zvishoma: Kudzika kudiki kunosara pamusoro pechinhu kunodzivirira kukuvadza maworkpiece, zvichiita kuti ive yakakodzera zvikamu zvakatetepa, macoatings epamusoro, uye kuyedzwa kwekuomarara kwenzvimbo diki.

3. Mashandisirwo Akajairika

Inoshandiswa zvakanyanya pakuongorora kuomarara kwezvikamu zvakarurama, machira epamusoro, uye machira matete—semuenzaniso, kuyera kuomarara kwemachira enharembozha kuti uone kana anoramba kupfeka. Pamusoro pezvo, inokosha mukutsvagisa kwesainzi pakuongorora kuomarara kwenzvimbo dzisingaonekwe, dzakadai sekuongorora kuomarara kwemiganhu yezviyo uye miganhu yezvikamu muzvinhu kuti udzidze hunhu hwezvinhu zvisingaonekwe.

4. Kuenzanisa Nzira Nhatu Dzekuyedza Hukukutu

5. Pfupiso
Nzira nhatu idzi dzekuyedza kuomarara dzine zvadzinobatsira. Nzira yakakodzera inofanira kusarudzwa zvizere zvichienderana nehunhu hwezvinhu, chimiro chemuenzaniso, huwandu hwekuomarara uye zvinodiwa nemazvo kuti uwane mhedzisiro yebvunzo inonzwisisika.

Dzvanya pano kuti uwane rumwe ruzivo nezvezvigadzirwa zvedu.
