ʻenehana Laser Cladding: Nā waiwai a me nā noi

Ka manawa e heluhelu ai: 4 min

Lapaʻau ʻili no ka hoʻopaʻa ʻana i ka laser 

ʻO ka ʻenehana hoʻopaʻa ʻana laser he ʻenehana hoʻololi ʻili hou i puka mai i ka makahiki 1970 me ka hoʻomohala ʻana i nā lasers mana kiʻekiʻe.ʻO ia hoʻi, ʻo ka ʻenehana hoʻopaʻa ʻana i ka ʻaoʻao laser he uhi ʻili i hoʻokumu ʻia e ka hoʻomehana wikiwiki a me ka hoʻoheheʻe ʻana i ka alloy a i ʻole ka pauka seramika me ka ʻili o ka substrate ma lalo o ka hana a ka kukuna laser, a laila hoʻohauʻoli iā ia iho ma hope o ka wehe ʻia ʻana o ke kukui e hana i kahi uhi ʻili. me ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka hoʻopaʻa ʻana me ka mea substrate.He ala hoʻoikaika kino kēia e hoʻomaikaʻi nui ai i ka pale ʻana i ka ʻaʻahu, ka pale ʻana i ka corrosion, ke kūpaʻa wela, ke kū ʻana o ka oxidation a me nā hiʻohiʻona uila o ka ʻili substrate.

No ka laʻana, ma hope o ka hoʻopaʻa ʻana i ka laser o ka tungsten carbide ma 60 mau kila, hiki i ka paʻakikī a hiki i 2200 HV a ʻoi aku paha, a ʻo ke kūpaʻa ʻana ma kahi o 20 mau manawa ma mua o ke kila 60 kumu.Ma hope o ka hoʻopaʻa ʻana i ka laser o CoCrSiB alloy ma ka ʻili o ke kila Q235, ua hoʻohālikelike ʻia kona pale ʻana me ke kūpaʻa ʻana o ka lapalapa ahi, a ua ʻike ʻia ka mea mua ma mua o ka hope.

Hiki i ka ʻenehana hoʻopili laser ke waiho pololei a koho ʻia me ka liʻiliʻi o ka wela wela i ka substrate lalo.ʻO ka hana ʻana i kēia paʻa mechanical ma waena o ka substrate a me ka papa ʻo ia kekahi o nā kaʻina hana wili pololei loa i loaʻa.

Lako no ka Hoopae Laser

Nā Pōmaikaʻi ma kahi Kiʻi

• ʻOi aku ka kūpaʻa o nā papa i hoʻoheheʻe ʻia ma mua o ka hoʻoheheʻe wela
• ʻO ka ʻenehana maikaʻi loa no ka uhi ʻana i kēlā me kēia ʻano
• ʻO ka hoʻokomo ʻana i ka wela haʻahaʻa haʻahaʻa ka hopena i kahi wahi wela haiki (EHLA a hiki i 10µm)
• Hoʻonui i ke ola lawelawe o nā ʻāpana hiki ke hoʻohana
• Hiki ke hoʻohana ʻia me nā ʻano mea like ʻole, me ka alloy maʻamau a i ʻole ka metala matrix composite (MMC) i hoʻolālā ʻia i nā substrate a me nā papa.
• ʻO ka maʻalahi i ke koho ʻana i nā mea (metala, keramika, a me nā polymers)
• ʻO ka maikaʻi o ka ʻili kiʻekiʻe a me ka warpage haʻahaʻa, koi liʻiliʻi a i ʻole ma hope o ka mālama ʻana
• pōkole pōkole manawa a me ka ikehu kiʻekiʻe o ka laser cladding kaʻina
• ʻO ka automation maʻalahi a me ka hoʻohui ʻana i nā kaiapuni hana CNC a me CAD/CAM
• He liʻiliʻi a ʻaʻohe porosity i loko o ka waihona (>99.9% density)

Noi o ka Laser Cladding Technology

Loaʻa ka ʻenehana hoʻopaʻa ʻana laser i nā ʻano noi, a hiki iā ʻoe ke nānā i nā noi ʻoihana maʻamau i loaʻa e hōʻoia inā kūpono lākou i kāu ʻano hoʻohana.ʻO kahi ʻē aʻe, hiki iā ʻoe e nānā i kā mākou ʻaoʻao pale laser no ka ʻike hou aku.Hiki ke hoʻohana ʻia ka ʻenehana laser cladding no ka hana wikiwiki, hoʻoponopono ʻāpana a me ka hoʻonui ʻana i ka ʻili, a he nui ka nui o nā noi e komo pū ana, ma ka ʻoihana kaʻa, FMCG, lāʻau lapaʻau a me nā ʻoihana hana.Hoʻohana maʻamau ia no ka hoʻoponopono hou ʻana, hana a hoʻoponopono ʻana i nā ʻāpana e like me nā mea hana, shafts, blades, turbines, drilling tools, etc. Eia kekahi mau hiʻohiʻona noi maʻamau:

• Aerospace turbine blades a hoʻoponopono
• Hoʻoponopono puke puke
• Nā puke pai a me nā wahi sila (ʻoihana sima)
• ʻO nā mea hoʻolele Turbocharger
• Mea hana wili
• Mekini mahiai
• Nā pahu hoʻopau
• Nā lāʻau piston
• Nā mea hoʻololi wela
• ʻO nā wili kaʻina hana kiʻekiʻe, ka paʻakikī a me ka pale ʻana i ka corrosion, nā lehelehe valve a me nā noho (cobalt 6)

Nā pōʻino ma kahi nānā

• ʻOiai he nui nā pōmaikaʻi o ka pale ʻana i ka laser, aia kekahi mau hemahema i ka ʻenehana, me:
• ʻO ke kumukūʻai kiʻekiʻe o nā mea hoʻopili laser
• ʻO nā mea hana nui ʻo ia ka mea maʻamau ʻaʻole hiki ke lawe ʻia, ʻoiai ke loaʻa nei nā hoʻonā kahua paʻa
• Hiki i nā kumukūʻai kiʻekiʻe ke alakaʻi i ka haki ʻana (ʻoiai no kekahi mau mea hiki ke hoʻopau ʻia me nā mana wela hou aʻe, e like me ka preheating a me nā mana hoʻoheheʻe post-deposition) Hoʻomaʻamaʻa a maloʻo loa ke kaʻina hana laser cladding, a hiki i 1012°C/s.Ma muli o ka ʻokoʻa ʻana o nā gradients wela a me nā coefficients o ka hoʻonui ʻana i ka wela ma waena o nā mea ʻaʻahu a me nā mea substrate, hiki ke hoʻomohala ʻia nā ʻano kīnā like ʻole i loko o ka papa lole, ʻo ia hoʻi me ka porosity, ka haki ʻana, ka distortion a me ka like ʻole o ka ʻili.

Ka Loiloi o ka Pono o ka Layer Cladding Layer

ʻElua mau mea e noʻonoʻo ai:

1Ma ka Macroscopically, ke nānā ʻana i ke ʻano o ke kahawai ʻaʻahu, ʻaʻohe kūlike o ka ʻili, nā māwae, porosity a me ka dilution rate.

2Ma ka pae microscopic, nānā ʻia ka hoʻokumu ʻana o ka hui maikaʻi a me ka hiki ke hāʻawi i nā waiwai i koi ʻia.Eia kekahi, pono e hoʻoholo ʻia ke ʻano a me ka hāʻawi ʻana i nā mea kemika o ka papa cladding surface, a pono e uku ʻia ka nānā ʻana inā he metallurgical hoʻopili ke kūlana o ka papa hoʻololi, a pono e hoʻokō ʻia ka hoʻāʻo ʻana i ke ola inā pono.

Paʻa ka hoʻopau ʻana o ka ʻili i ka hana a me ke koʻikoʻi aesthetic no nā ʻāpana ʻoihana.Me ka holo wikiwiki ʻana o nā ʻoihana, ʻoi aku ka paʻakikī o nā koi hoʻomanawanui a no laila ʻoi aku ka maikaʻi o ka hoʻopau ʻana i ka ʻili no nā huahana kiʻekiʻe.Loaʻa nā ʻāpana me nā hiʻohiʻona maikaʻi i ka waiwai nui ma ka mākeke.Hiki ke hoʻololi nui ka hoʻopau ʻana o waho o waho i ka hana kūʻai ʻana o kahi ʻāpana.

Hāʻawi nā lawelawe hoʻopau ʻili o Prolean Tech i ka maʻamau a me nā hoʻopau ʻili kaulana no nā ʻāpana.Hiki i kā mākou mīkini CNC a me nā ʻenehana hoʻopau ʻilikai ʻē aʻe ke hoʻokō i nā hoʻomanawanui paʻa a me nā kiʻekiʻe kiʻekiʻe, nā ʻano like ʻole no nā ʻāpana āpau.E hoʻouka wale i kāufaila CADno ka wikiwiki, manuahi a kūkākūkā i nā lawelawe pili.
