Rīpene Nichrome 80/20 Kounga Teitei mō te Ahumahi Taputapu Hiko

Whakaahuatanga Poto:

Ko te waea nichrome 80/20 he koranu kore-aukume, he teitei te ira rewa me te ātete ki te waikura. Nā te pai o te mahi me te kaha ki te pāmahana teitei, he whānuitia te whakamahinga mō ngā mahi taumaha i roto i te umanga taputapu hiko.

    Ngā Tohu Hua

    He rauemi ātete-teitei ngā koranu Nickel Chrome (NiCr) e whakamahia whānuitia ana i ngā tono me ngā pāmahana mahi mōrahi tae atu ki te 1,250°C (2,280°F).

    E mōhiotia ana ēnei koranu Austenitic mō tō rātou kaha miihini teitei ake i ngā pāmahana ki te whakataurite ki ngā koranu FeCrAl me tō rātou kaha ngoki teitei ake. Ka noho ngāwari ake hoki ngā koranu Nickel Chrome ki te whakataurite ki ngā koranu FeCrAl i muri i ngā wā roa i te pāmahana. Ka hangaia he Chromium Oxide pouri (Cr2O3) i ngā pāmahana teitei, ā, ka ngawari ki te pakaru, ki te pakaru rānei, ka puta he poke pea i runga i te whakamahinga. Kāore he āhuatanga whakamarumaru hiko o tēnei waikura pērā i te Konumohe Oxide (Al2O3) o ngā koranu FeCrAl. He pai te ātete waikura o ngā koranu Nickel Chrome, engari ki ngā taiao kei reira te whanariki.
