Nickel Base Alloy me ka oxidation a me ka corrosion
Palapala noi
ʻO ka Nickel base alloy powder kahi mea hana kiʻekiʻe i hoʻohana nui ʻia i nā ʻoihana like ʻole, ʻoi aku ka nui o ka wela a me ka corrosive.ʻO kona kūpaʻa corrosion maikaʻi a me ke kūpaʻa hoʻonā wela kiʻekiʻe e lilo ia i mea koho kaulana no nā uhi ma ke kila a me nā ʻāpana haʻahaʻa haʻahaʻa ma lalo o nā kūlana wela kiʻekiʻe.Hoʻohana ʻia ʻo ia ma ke ʻano o ka hoʻopaʻa ʻana o ka carbide coating, e hana ana ia i kahi koho kūpono no nā noi pale ʻaʻahu.
Waiwai
Hoʻokumu ʻia ka pauka me ka nickel, chromium, a me nā mea ʻē aʻe, e hāʻawi iā ia i ke kūpaʻa corrosion maikaʻi loa a me ke kūpaʻa kiʻekiʻe.Hiki i ka pauka ke hana i kahi uhi hiki ke hana ma nā mahana a hiki i 980ºC, kūpono ia no ka hoʻohana ʻana i nā wahi paʻakikī.Loaʻa ka paʻakikī maikaʻi a me ka hana mechanical i ka uhi, kahi e kūpono ai no ka hoʻohana ʻana i nā noi pale lole.
Hana ʻana
Hana ʻia ka pauka nickel base alloy me ka hoʻohana ʻana i ke kaʻina hana atomization kinoea.ʻO ke kaʻina hana ka hoʻoheheʻe ʻana i nā mea maka a laila ʻātomi iā lākou i loko o kahi pauka maikaʻi me ka hoʻohana ʻana i ke kinoea kiʻekiʻe.ʻO ka pauka i loaʻa i ka nui o nā ʻāpana like ʻole a me ka flowability maikaʻi, kahi e maʻalahi ai ka lawelawe a me ka hana.
Hoʻohana
Hoʻohana nui ʻia ka Nickel base alloy powder i nā ʻoihana like ʻole, me ka aerospace, ka hana mana, a me ka hana kemika.Hoʻohana maʻamau ia ma ke ʻano he mea uhi no ka pale ʻana i ke kila a me nā ʻāpana kila haʻahaʻa haʻahaʻa ma lalo o nā kūlana kiʻekiʻe a me nā kūlana corrosive.Hoʻohana ʻia ʻo ia ma ke ʻano o ka hoʻopaʻa ʻana o ka carbide coating, i mea kūpono no nā noi pale ʻaʻahu.Hiki ke hoʻohana ʻia ka pauka me ka hoʻohana ʻana i nā kaʻina hana hoʻoheheʻe wela, e pili ana i ka lapalapa ahi, ka ʻūhā plasma, a me ka pākī oxy-fuel kiʻekiʻe (HVOF).
Ka hopena
ʻO ka Nickel base alloy powder kahi mea hana kiʻekiʻe i hoʻohana nui ʻia i nā ʻoihana like ʻole no kāna kūpaʻa corrosion maikaʻi loa a me ke kūpaʻa ʻana o ka wela kiʻekiʻe.ʻO ke kaʻina hana atomization kinoea e hōʻoiaʻiʻo i ka nui o ka nui o ka pauka a me ka flowability maikaʻi, e maʻalahi ke mālama a me ka hana.ʻO kona kūpaʻa paʻa kiʻekiʻe, paʻakikī, a me ka hana mechanical e lilo ia i mea koho maikaʻi loa no ka hoʻohana ʻana i nā kaiapuni paʻakikī a me nā noi pale lole.
