Wehewehe: He electrode kila ikaika kiʻekiʻe ʻo J707Ni me ka uhi sodium haʻahaʻa-hydrogen. Hoʻohana i ka DCEP (electrode au pololei maikaʻi) a hiki ke hoʻopaʻa ʻia ma nā kūlana āpau. He maikaʻi nā waiwai mechanical o ka metala i waiho ʻia. Ke hoʻohālikelike ʻia me ka electrode J707, ʻo ka hiʻohiʻona nui o J707Ni ʻo ia ka paʻakikī o ka mahana haʻahaʻa a me ke kūpaʻa ʻana i ka haki.

Noi: Hoʻohana ʻia no ka hoʻopili ʻana i nā ʻano kila ikaika haʻahaʻa o nā pae ikaika like, e like me 14MnMoVB, WEL-TEN70 a me Iapana HW56 a me nā ʻano kila ikaika haʻahaʻa ʻē aʻe.

Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):

Nā ʻano mechanical o ka metala i hoʻoheheʻe ʻia:

Ka nui o ka hydrogen diffusion o ka metala i waiho ʻia: ≤4.0mL/100g (ʻano glycerin) 

Nānā X-ray I级: papa I

Manaʻo ʻia kēia manawa:

Hoʻolaha:

1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma 350 ~ 380 ℃ ma mua o ka hana kuʻihao;

2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka unahi ʻaila, ka wai, a me nā mea haumia ma nā ʻāpana wili ma mua o ka wili ʻana;

3. E hoʻohana i ka hana arc pōkole i ka wā e kuʻi ai. He kūpono ke ala kuʻi haiki.
