ʻO Chromium Carbide Powder Mea hoʻolako maʻemaʻe kiʻekiʻe
Hōʻike huahana
ʻO ka chromium carbide metala chromium (chromium trioxide) a me ke kalapona i carbonized i loko o ka hakahaka.ʻO Cr3C2 kāna kumu mole (ʻo ka pākēneka kaumaha o ke kalapona he 13%), ʻo 6.2g/cm3 ka mānoanoa a ʻoi aku ka paʻakikī ma luna o HV2200.ʻO ka hiʻohiʻona o ka pauka chromium carbide he kala hina. ʻO ka pauka Chromium carbide kahi mea hoʻoheheʻe kiʻekiʻe me ke kūpaʻa maikaʻi o ka lole, ka pale ʻana i ka corrosion a me ke kūpaʻa oxidation i ke kaiapuni kiʻekiʻe (1000-1100 degere).

He maikaʻi a maikaʻi ʻole ka lattice o ka chromium carbide, me kahi helu heheʻe o 1895 ° C. Ma muli o kāna mau hiʻohiʻona maikaʻi loa o ke kūpaʻa lole kiʻekiʻe, ke kūpaʻa corrosion a me ke kūpaʻa wela kiʻekiʻe, hoʻohana nui ʻia i:
●Ka hana ʻana i nā mea hoʻoheheʻe kūikawā, nā electrodes moʻo i luna, nā uea flux-cored.
●Cmented carbide, hoʻohui i ka Cr3C2 i ka hana ʻana i ka cemented carbide ʻaʻole hiki ke hoʻomaʻemaʻe wale i nā kīʻaha WC, akā hoʻomaikaʻi hoʻi i ka ikaika a me ka paʻakikī o ka paʻa, a hiki ke hoʻomaikaʻi nui i ke kūpaʻa ʻana o ka corrosion.
●Thermal spraying powder material, ma muli o Cr3C2 a me ka hoʻohui ʻana i ka Nicr superalloy i ka pauka alloy i hana ʻia, me ka hoʻohana ʻana i ka plasma spraying, hiki ke hana i nā lole pale kiʻekiʻe, corrosion-resistant, kiʻekiʻe-mehana pale pale, hoʻohana nui ʻia i nā lau fan, ua haki nā sila. ʻO ka paila "ʻehā mau paipu", etc.
●Arc sprayed uea a submerged arc welded tubular uea, ke arc sprayed uea ua hoʻohuiʻia me Cr3C2 mea, e hoʻomaikaʻi i ke kiʻekiʻe wela kū'ē a me ka lole pale.Hoʻohana ʻia ia i ka hoʻoponopono ʻana a me ka mālama pale ʻana i nā "paipu ʻehā" o ka paila, a me ke kūpaʻa ʻana o ka hao-hana lole lole i loko o ka ʻoihana metallurgical.Lining pā, mana kanu lanahu wili kala, no ka hoʻohana 'ana o Cr3C2 hoʻohui tubular kuʻihao uwea surfacing pale, nui hoʻomaikaʻi i ke ola lawelawe.
