Ngā tikanga whakamātautau pakeke a Rockwell Knoop me Vickers mō ngā uku konumohe nitride me ngā tikanga whakamātautau mō ngā peera hurihuri whakarewa.

1. Tikanga whakamātautau pakeke a Rockwell Knoop Vickers mō ngā uku konumohe nitride
Nā te mea he uaua te hanganga o ngā rauemi uku, he mārō, he pakarukaru hoki te āhua, ā, he iti noa te āhua kirihou o te rauemi, ko ngā tikanga whakaatu mārō e whakamahia whānuitia ana ko te mārō o Vickers, te mārō o Knoop me te mārō o Rockwell. He whānuitanga ngā momo whakamātautau mārō a te Kamupene Shancai, me ngā whakamātautau mārō rerekē me ngā momo whakamātautau mārō e pā ana.
Ka taea te whakamahi i ngā paerewa e whai ake nei hei tohutoro:
GB/T 230.2 Whakamātautau Pakari Rockwell Rauemi Whakarewa:
He maha ngā tauine pakeke a Rockwell, ā, ko te tikanga ka whakamahia e ngā rauemi uku ngā tauine HRA, HRC rānei.
Whakamātautau pakeke GB/T 4340.1-1999 Metal Vickers me te whakamātautau pakeke GB/T 18449.1-2001 Metal Knoop.
He rite tonu ngā tikanga ine a Knoop me Micro-Vickers, ko te rerekētanga kei ngā momo kōhao e whakamahia ana.
He mea tika kia mōhiotia, nā te āhua motuhake o te hua, ka taea e tātou te tango i ngā kōhao Vickers kore whaimana i runga i te āhua o te kōhao i te wā ine kia whiwhi ai i ngā raraunga tika ake.
2. Ngā tikanga whakamātautau mō ngā peera hurihuri whakarewa
E ai ki ngā tikanga whakamātautau pakeke mō ngā wāhanga maitai me ngā wāhanga konganuku kore-whakarewa kua tohua i roto i te JB/T7361-2007, he maha ngā tikanga whakamātautau e ai ki te tukanga mahi, ā, ka taea te whakamātautau i ēnei katoa ki te taputapu whakamātautau pakeke Shancai:
1）Tikanga whakamātautau pakeke a Vickers
Ko te tikanga whakamātautau pakeke a Vickers te tikanga whakamātautau pakeke o ngā wāhanga whēra mata kua whakapakeketia. Me aro nui ki te āhua o te mata o te mea mahi me te whiriwhiri i te kaha whakamātautau.
2）Tikanga whakamātautau pakeke o Rockwell
Ko te nuinga o ngā whakamātautau pakeke o Rockwell e whakahaerehia ana mā te whakamahi i te tauine HRC. E 15 tau te wheako o Shancai Rockwell i roto i te whakamātautau pakeke, ā, ka taea e ia te whakatutuki i ngā hiahia katoa.
3）Tikanga whakamātautau pakeke Leeb
Ka taea te whakamahi i te whakamātautau pakeke Leeb mō ngā peera kua tāutahia, he uaua rānei ki te wetewete. Kāore tōna tika i te rite te pai ki te ine i te tika o te ine i te mea he taputapu whakamātautau pakeke papa.
Ko te nuinga o tēnei paerewa e pā ana ki te whakamātautau pakeke o ngā wāhanga whīra rino, ngā wāhanga whīra kua whakamahanatia me ngā wāhanga whīra kua whakamahanatia, ngā wāhanga whīra kua oti te whakaoti me ngā wāhanga whīra konganuku kore-ferrous.
