ʻO nā paipu kila pale Chromeua uhi ʻia me kahi ʻāpana metala ma ka ʻili o ka metala paipu kila ma o ka electroplating.ʻO ke kumu nui o nā paipu kila chromium plated ka pale.ʻO nā paipu kila i hoʻopaʻa ʻia ʻo Chromium he paʻa kemika maikaʻi a ʻaʻole hoʻi i ka alkali, sulfides, nitric acid, a me ka hapa nui o nā waikawa organik.Hiki ke hoʻoheheʻe ʻia nā paipu kila chromium i loko o ka waika hydrochloride (e like me ka waika hydrochloride) a me ka waikawa sulfuric wela.ʻO ka lua, ʻoi aku ka maikaʻi o ka pale ʻana o ka chromium plating, a ʻo nā paipu kila chromium plated wale nō ka oxidize a me ka discolor ke ʻoi aku ka mahana ma mua o 500 degere Celsius.Eia kekahi, ʻo kāna ʻāpana friction, ʻoi aku ka nui o ka friction coefficient, ʻo ia ka mea haʻahaʻa loa ma waena o nā metala āpau, a ʻo nā paipu kila i hoʻopaʻa ʻia i ka chrome he kūpaʻa maikaʻi loa.Ma ka laula kukui ʻike ʻia, ʻo ka hiki ke noʻonoʻo o ka chromium ma kahi o 65%, ma waena o ke kālā (88%) a me ka nickel (55%).ʻAʻole hoʻololi ka Chromium i ke kala, a hiki i nā paipu kila i hoʻopaʻa ʻia i ka chrome ke mālama i ko lākou hiki ke noʻonoʻo no ka manawa lōʻihi ke hoʻohana ʻia, ʻoi aku ka maikaʻi ma mua o ke kālā a me ka nickel.ʻEkolu ʻano o nā kaʻina hana chrome plated.
1. Palekana - Hoʻopololei Chromium Plating - ʻO ka Plating Chromium Decorative, i ʻike nui ʻia ʻo Decorative Chromium, loaʻa kahi uhi lahilahi a ʻālohilohi i hoʻohana mau ʻia e like me ka papa waho o ka multi-layer electroplating.No ka hoʻokō ʻana i nā kumu palekana, pono e hoʻopili mua ʻia kahi papa waena mānoanoa ma luna o ka zinc based a i ʻole ka substrate kila, a laila pono e uhi ʻia kahi papa waena mālamalama o 0.25-0.5 ma luna o ia μ ʻO ka chromium papa lahilahi o ka m.ʻO nā kaʻina hana maʻamau me Cu / Ni / Cr, Ni / Cu / Ni / Cr, Cu Sn / Cr, a me nā mea'ē aʻe. Ma hope o ka hoʻonaniʻana i kaʻili o ka huahana me ka hoʻonani chromium plating, hiki ke loaʻa kahi luster aniani kala.ʻAʻole ia e hoʻololi i ka waihoʻoluʻu ma hope o ka loaʻa ʻana i ka lewa.Hoʻohana nui ʻia kēia ʻano uhi no ka pale ʻana a me ka hoʻonani ʻana i nā ʻāpana e like me nā kaʻa, nā paikikala, nā mīkini humuhumu, nā wati, nā mea kani, a me nā lako i kēlā me kēia lā.ʻO ka papa chromium hoʻonani i hoʻonani ʻia he hiki ke hoʻomālamalama kiʻekiʻe a hiki ke hoʻohana ʻia e like me ka reflector.ʻO ka hoʻopaʻa ʻana i nā micro pores a i ʻole microcracks o chromium ma luna o ka nickel multi-layer he ala koʻikoʻi e hōʻemi i ka nui o ka mānoanoa o ka uhi ʻana a loaʻa i kahi ʻōnaehana hoʻonaninani me ka pale pale pale kiʻekiʻe.ʻO ia hoʻi ke kuhikuhi hoʻomohala o nā kaʻina hana electroplating hou.
2. ʻO ka chromium paʻakikī (ʻaʻahu-kūpono chromium) plating he kiʻekiʻe loa ka paʻakikī a me ke kū'ē kū'ē, hiki ke hoʻonui i ke ola lawelawe o nā mea hana, e like me kaʻokiʻoki a me ke kaha kiʻi, ka paʻiʻana a me ka hoʻoleiʻana i nā mea likeʻole, nā bearings, shafts, gauges, gears , etc., a hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana i ka hoʻomanawanui ʻana o nā ʻāpana kahiko.ʻO ka mānoanoa o ka paʻa chromium paʻakikī he 5-50 μm.Hiki ke hoʻoholoʻia e like me nā mea e pono ai,ʻo kekahi e like me ka 200-800 μ M. ʻO ka paʻakikī chromium plating ma nā'āpana kilaʻaʻole e koi i ka uhi waena.Inā loaʻa nā koi kūikawā no ka pale ʻana i ka corrosion, hiki ke hoʻohana ʻia nā ʻāpana waena like ʻole.
3. He keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo chromium keʻokeʻo, me ka liʻiliʻi liʻiliʻi, ka paʻakikī maikaʻi, ka porosity haʻahaʻa, a me ke kala palupalu.ʻOi aku ka haʻahaʻa o kona paʻakikī ma mua o ka chromium paʻakikī a me ka chromium decorative, akā he kiʻekiʻe ke kūpaʻa corrosion, no laila hoʻohana maʻamau ia i ke ana ʻana i nā mea hana a me nā panela mea kani.No ka hoʻomaikaʻi ʻana i kona paʻakikī, hiki ke hoʻopili ʻia kahi papa o ka chromium paʻakikī, ʻike ʻia hoʻi he ʻāpana chromium papalua, ma ka ʻili o ka uhi keʻokeʻo milky, e hoʻohui i nā ʻano o ka chromium keʻokeʻo milky a me ka chromium paʻakikī.Hoʻohana pinepine ʻia ia no ka uhi ʻana i nā ʻāpana e koi ai i ka pale ʻana a me ke kūpaʻa corrosion.
4. Hoʻohana ka porous chromium plating (porous chromium) i nā hiʻohiʻona o nā māwae maikaʻi ma ka papa chromium ponoʻī.Ma hope o ka hoʻopaʻa ʻana i ka chromium paʻakikī, hoʻokō ʻia ka mālama ʻana i ka porosity mechanical, chemical, a electrochemical paha e hoʻonui a hoʻonui i ka ʻupena māwae.ʻO ka ʻili o ka papa chromium ua uhi ʻia me nā ʻāpana ākea, ʻaʻole wale nā hiʻohiʻona o ka chromium pale ʻaʻahu, akā mālama maikaʻi hoʻi i ka media lubricating, pale i ka hana ʻole lubricated, a hoʻomaikaʻi i ka friction a me ke kūpaʻa ʻana o ka papa hana.Hoʻohana pinepine ʻia no ka hoʻopili ʻana i ka ʻili o nā ʻāpana friction Sliding ma lalo o ke kaomi koʻikoʻi, e like me ke keʻena o loko o ka pahu pahu pahu pahu pahu, piston apo, etc.
⑤ ʻO ka uhi ʻana i ka chromium ʻeleʻele ʻeleʻele he ʻano luster, hoʻonani maikaʻi, a me ka hoʻopau maikaʻi ʻana;He kiʻekiʻe ka paʻakikī (130-350HV), a he 2-3 mau manawa ke kiʻekiʻe o ke kūpaʻa ʻaʻahu ma mua o ka nickel mālamalama ma lalo o ka mānoanoa like;ʻO kona kūpaʻa corrosion e like me ka chromium plating maʻamau, ma muli o ka mānoanoa o ka papa waena.Kūleʻa wela maikaʻi, ʻaʻohe discoloration ma lalo o 300 ℃.Hiki ke hoʻopili pololei ʻia ka papa chromium ʻeleʻele ma ka ʻili o ka hao, keleawe, nickel, a me ke kila kila.No ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion a me ka hopena hoʻonaninani, hiki ke hoʻohana ʻia ke keleawe, nickel, a i ʻole ke keleawe keleawe e like me ka papa lalo, a hiki ke uhi ʻia kahi uhi chromium ʻeleʻele ma luna o kona ʻili.Hoʻohana maʻamau ka uhi ʻeleʻele chromium e uhi i ka pale a me ka hoʻonani ʻana o nā ʻāpana o nā mea hana mokulele a me nā mea Optical, nā paneli hoʻoheheʻe ʻana i ka ikehu o ka lā a me nā mea e pono ai i kēlā me kēia lā.
