Hāʻawi ʻo Ningbo De-Shin i ka piha piha o ka tungsten kālā no nā ʻano noiʻi ʻoihana like ʻole.Lawe ʻo ia i ke kaʻina hana infiltration vacuum holomua a hoʻokō nā huahana āpau i ka criterion o GB/T8320-2003, ASTM B631.
Kaʻina hana:hui pauda -> kaomi -> hoʻopaʻa ʻia -> hoʻoheheʻe ʻia i ka lepo -> hoʻoheheʻe ʻia -> QC.Hoʻopili paʻa ʻia kēia kaʻina hana āpau e QC e hōʻoia i ka hana maikaʻi loa.
Pono:
1. Kiʻekiʻe uila conductivity.
2. Kiʻekiʻe thermal conductivity.
3. High density me ka pono uniformity microstruction o mea.
Nā noi:
1. Kaapuni kaapuni.
2. Nā mea hoʻokahe honua.
3. Nā mea hoʻomaha kaapuni liʻiliʻi.
4. kū'ē kuʻihao electrode.
5. komo i ke kumu kū'ē
Nui waiwai:
