Hoʻohana & Kūlana
GEH-547Mo he electrode lima e pili ana me GB/T984 ED CrNi-B-15, i hoʻohana ʻia i nā ʻano like ʻole o ka hoʻoheheʻe ʻana i luna a me ka hoʻoheheʻe ʻana i ka metala. Hoʻohana nui ʻia ia no ka hoʻopili ʻana i ka ʻili o ka valve sealing kiʻekiʻe me ka mahana hana ma lalo o 600 ℃. Ma ka hoʻokuʻu ʻana i ka alloy kikoʻī ma ka ʻili o ka substrate, hiki iā ia ke hoʻokō i nā pono o ka pale ʻana a me ke kūpaʻa corrosion. ʻO ke kūpaʻa wela kiʻekiʻe a i ʻole ka hui pū ʻana o nā kūlana hana. ʻO ka hōʻemi ʻana i nā kumukūʻai hana, ka hoʻomaikaʻi ʻana i ka hoʻohana ʻana i nā huahana ma o ka hoʻoponopono hou ʻana, a i ʻole ka hoʻomaʻamaʻa ʻana i ka mana o ke kūkulu ʻana a me ke ʻano o ka mea hana, ʻo ia ke ʻano maʻalahi a maʻalahi. ʻO ka mea i kapa ʻia ʻo ka ʻenehana paʻa paʻa i kapa ʻia ʻo ia ka hoʻoheheʻe ʻana i ka ʻili metala, ka hoʻoulu ʻana a i ʻole ka hoʻoponopono ʻana.
Nā hiʻohiʻona
ʻO GEH-547Mo kahi haʻahaʻa sodium hydrogen i uhi ʻia kiʻekiʻe chromium nickel valve surfacing electrode, me ka hoʻohana ʻana i ka pilina hoʻohuli DC. Hoʻoikaika ʻia ka metala i luna e Si, Mo, W, V, Nb a me nā mea ʻē aʻe e loaʻa ai ke ʻano autonitic me kahi liʻiliʻi o ka ferrite, kahi maikaʻi kiʻekiʻe kiʻekiʻe abrasion kū'ē a me ka erosion kū'ē, kiʻekiʻe wela paakiki, maikaʻi thermal paʻa a me ka wela. pale ʻana i ka luhi. He mea kupaianaha ka hopena paʻakikī o ka hoʻokele metala. Me ka piʻi ʻana o ka wā ʻelemakule, hoʻomaikaʻi hou ʻia ka paʻakikī a me ka pale ʻana i ka abrasion. He kūpono ia no ka hoʻopili ʻana i ka ʻili o ka paʻi kiʻekiʻe me ka mahana hana ma lalo o 600 ℃, nā ʻano ʻano pahu valve āpau, ka noho valve, ka pā pā, ke poʻo kīwaha nui, ke kumu palekana a me ka disc valve, etc.
