Whakaahuatanga: Ko te Ni307-3 henikarahe hiko e hangai ana ki te hauota me te paninga konutai hauwai-iti. Whakamahia te DCEP (hiko au tika). He pai te ātete ki te pakaru nā te mea kei roto i te whakarewa he nui o te konupora, te niobium, me ētahi atu huānga whakarewa.

Taupānga: E whakamahia ana mō te whakarewa onikara-ngā koranu konukōmiuma-rino (pērā i te UNS N06600) me te mata o te maitai. Ko te pāmahana mahi kāore i te neke ake i te 480 °C, ā, he pai te ātete ki te pakaru. He pai mō te whakarewa i te oko pēhanga oumu ngota me te tāke matū.

1. Me tunu te hiko mō te 1 hāora i te pāmahana tata ki te 300℃ i mua i te mahi whakarewa;

2. He mea nui kia horoia ngā waikura, te hinu, te wai, me ngā poke i runga i ngā wāhanga whakarewa i mua i te whakarewa. Whakamātauria te whakamahi i tētahi pewa poto hei whakarewa.
