He Aratohu Kotahi-Hipanga hei Kōwhiri i te Momo Tika
Kōwhiria i runga i ngā āhuatanga e rima: te rahi o te rauemi mahi, te rauemi, te whānuitanga o te pakeke, ngā whakaritenga tika, me ngā horopaki tono. Kāore he take e manukanuka ai, me whai noa i te aratohu, ā, ka taea e koe te whakatau.
I. Tuatahi, whakarōpūtia kia toru ngā momo matua o ngā whakamātautau mārō
1. Rockwell Hardness Tester (HRC/HRB/HRA)
He pai mō: te maitai kua tineia, te maitai kua mate, ngā peera, ngā taputapu, ngā wāhanga kua tukatukahia ki te wera
Ngā Painga: he tino tika, he whānuitia te whakamahinga i roto i ngā paerewa ā-motu, he taputapu paerewa mō te tirotiro kounga o te wheketere
Ngā ngoikoretanga: me tango tauira / momo papamahi, kāore e taea te neke, te whakamātautau rānei i ngā wāhanga nunui i te papaanga
Ngā mea hei ine:
HRC: maitai pakeke-tio (ngā mate, ngā taputapu, ngā taputapu)
HRB: parahi, konumohe, maitai waro-iti, maitai ngohengohe
2. Kaiwhakamātautau Pakeke Brinell (HB)
He pai mō: te rino maka, te maitai maka, te koranu konumohe, te koranu parahi, ngā wāhanga hanga taratara
Ngā Painga: he nui te kōhao, he tino tika mō ngā rauemi matotoru me ngā rauemi kore-taurite
Ngā ngoikoretanga: he nui te kōhao, he whakangaro, he iti te whai huatanga, he pai mō ngā tirotiro taiwhanga
3. Whakamātautau Pakeke a Leeb (kawe HL ki HRC/HB/HV)—Kaiwhakamātautau Pakeke Leeb YY251D
He pai mō: ngā wāhanga nunui, ngā whakamātautau i te papaanga, ngā wāhanga kāore e taea te wetewete, ngā pokepokea taumaha, ngā rōra, ngā toki
Ngā Painga: ka taea te pupuri me te kawe, kāore e whakangaro, kāore e hiahiatia he tauira, ka taea te whakamahi i ngā tūranga poutū, whakapae, i runga rānei
Ngā ngoikoretanga: he iti ake te tika o te taputapu i tō te papamahi Rockwell, he nui ngā hapa mō ngā wāhanga angiangi me ngā wāhanga iti.
II. Kōwhiria i runga i ngā horopaki tono (tino whaihua)
Horopaki 1: taiwhanga awheawhe, tirotiro kounga rauemi/maimoatanga wera e haere mai ana, me tino tika te mahi Kōwhiria he taputapu whakamātautau pakeke Rockwell papamahi
He pai ake mō ngā wheketere taputapu whānui, te hanga mate, me ngā wheketere maimoatanga wera.
Horopaki 2: rino maka, whakarewanga, koranu konumohe, wāhanga hanga taratara
Kōwhiria he taputapu whakamātautau mārō Brinell
Horopaki 3: ngā wāhanga nunui kāore e taea te neke, te whakamātautau i te papaanga, ngā pokepokea/ngā rōra/ngā toki nunui Me whiriwhiri he taputapu whakamātautau pakeke Leeb kawe
Horopaki 4: ngā wāhanga iti, ngā rau angiangi, te pakeke o te mata o ngā paparanga waro me te nitride Kōwhiria he whakamātautau pakeke Vickers (HV)
He pai mō: ngā pepa angiangi, ngā taha taputapu, ngā paninga, ngā paparanga whakapakeke.
III. Tīpakohia i runga i te matotoru/rahi o te rauemi mahi
Ngā wāhanga nunui, taumaha, me te kore e nekeneke → Leeb
Ngā tauira paerewa, ngā wāhanga iti, ka taea te whakanoho ki runga i te papamahi → Rockwell
Ngā wāhanga angiangi < 3mm, ngā paparanga mata kua whakapakeketia → Vickers
Te whakarewa i ngā mea parakore, ngā rauemi kore-taurite → Brinell
IV. Tīpakohia i runga i te taumata mārō
Rauemi ngohengohe: konumohe, parahi, maitai waro-iti → HRB / HB
Pakari waenga: maitai kua tineihia, kua whakamaroketia, maitai hanganga → HRC / HB
Te pakeketanga teitei: ngā mate kua tineia, ngā taputapu, ngā peera → HRC / HV
Ngā paparanga mata tino angiangi / ngā paparanga warowaihā → HV Vickers
