I kēia lā ke kūkākūkā nei mākou i ka hoʻopili ʻana o ka electro-spark deposition i nā ʻāpana metala, i ka manawa like e kālele mākou i kēia ʻenehana pehea e hoʻololi ai i ka ʻōpala i nā mea hana hoʻoheheʻe a me ka hoʻolei ʻana.
He aha ka Electro-Spark Deposition?
Electro-spark treatment, also known as Electro-discharge machining (EDM), is a special manufacturing process that involves the use of electrical discharges to shape and modified the surface of metal parts.
I ka wā o ka hoʻomaʻamaʻa Electro-spark, hana ʻia kahi hoʻokuʻu uila ma waena o kahi electrode a me ka mea hana, maʻamau i hana ʻia me nā mea conductive e like me ke kila a i ʻole nā mea hao.Hoʻomaka ke kaʻina hana ma ke kau ʻana i ka electrode, pinepine i ke ʻano o kahi mea hana liʻiliʻi, ma kahi kokoke i ka mea hana.
Ke hoʻohana ʻia ka volta ma waena o ka electrode a me ka mea hana, hiki mai ke ʻano o ka hoʻokuʻu uila wikiwiki.Hoʻokumu kēia mau hoʻokuʻu ʻana i ka wela nui, hoʻoheheʻe i nā ʻāpana liʻiliʻi o ka ʻili o ka mea hana.Hoʻopiʻi koke ʻia ka metala i hoʻoheheʻe ʻia e ka wai dielectric, e hoʻopaʻa ai a hana i nā lua liʻiliʻi a i ʻole nā indentations.
Hoʻohana ʻia ʻo ESD i nā ʻāpana metala
Ke hoʻokuʻu ʻia ka ikehu capacitor, hana ke au pololei i kahi arc plasma kiʻekiʻe ma waena o ka piko electrode a me ka mea hana metala.Aia kēia pae wela ma waena o 8000 a me 25000°C.Hoʻopili ka plasma arc i ka anode a hoʻololi koke i ka mea hoʻoheheʻe i ka mea hana.
Hoʻololi ʻia kēia anode ionizing i ka substrate ma o nā pulu pōkole.ʻO ke arc wela kiʻekiʻe he ʻanode particles, kahi kahe wela (hot jet), a me ka plasma i hana ʻia e ka decomposition o nā kinoea a me nā ʻātoma reactive o ka nitrogen, oxygen, a me carbon.Lawe ʻia ka hapa nui o ka wela e nā jet thermal a me ka plasma.
Ma muli o ka pōkole o nā pulupulu, he liʻiliʻi ka hoʻoili wela ma o ka jet thermal a me nā kinoea ʻē aʻe, a ʻo ka hoʻoili wela wale nō i ka substrate ma o ka helu liʻiliʻi o nā mea anode i waiho ʻia ma ka substrate.No laila, hoʻololi kēia mau pulse i kahi liʻiliʻi o ka wela i ka substrate me ka hoʻololi ʻole i ka microstructure o ka substrate.ʻOi aku ka maikaʻi o kēia ʻano hana ma mua o ke kaʻina hana kuʻi ʻana i hoʻohana mau ʻia no ka hoʻoponopono ʻana i nā alloys me nā ʻāpana ʻāina i hoʻopilikia ʻia i ka wela (e laʻa, haʻahaʻa ʻoʻoleʻa, paʻakikī kiʻekiʻe, māwae liquefaction).
Hoʻohui, kōkua ke kaʻina hana i kahi paʻa metallurgical ikaika ma waena o ka substrate a me ka uhi.ʻO ka microalloying ma waena o ka electrode melt a me ka substrate e hoʻomaka i ka hoʻokumu ʻana o ka plasma ma o ka decomposition ea, carbonates, carbide a me nitrides.
Pono
1.Precision a me ka pololei: Electro-spark lapaʻau hiki no ka pololei a me ka pololei shapeping o intricate kiko'ī a paʻakikī contours ma luna metala surfaces.ʻO ka hoʻokuʻu ʻia ʻana o ka uila e hoʻopau i ka mea ma ke ʻano hoʻomalu, hiki ke hana i nā hiʻohiʻona kikoʻī e like me nā puka liʻiliʻi, nā puka, a i ʻole nā indentations me ka pololei kiʻekiʻe.
2.Preservation of Material Integrity: ʻO kekahi o nā pono nui o ka mālama ʻana i ka Electro-spark ʻo ia ka hiki ke mālama i ka paʻakikī a me ka pololei o ka mea hana.ʻAʻole e like me nā ʻano mīkini kuʻuna e hiki ke hoʻoulu i ka wela nui a hoʻoulu i nā loli makemake ʻole i nā waiwai waiwai, ʻo ka mālama ʻana i ka Electro-spark e hōʻemi i nā ʻāpana wela a mālama i ka paʻakikī o ka mea hana.
3.Complex Geometries: Hiki i ka hoʻomaʻamaʻa electro-spark ke hana i nā geometries paʻakikī i paʻakikī a hiki ʻole ke hoʻokō me nā ʻano mīkini maʻamau.ʻO kona hiki ke hana i nā hiʻohiʻona paʻakikī e hiki ai ke hana i nā mold, make, a i ʻole nā mea ʻē aʻe me nā contours kūʻokoʻa a me nā kikoʻī paʻakikī, e hoʻonui ana i nā hiki ke hoʻolālā.
4. ʻAʻohe Mea Hana Hana: ʻAʻole like me nā ʻano hana machining maʻamau e pili ana i ka ʻoki ʻana a i ʻole abrasion, ʻaʻole pili ka mālama ʻana i ka Electro-spark i ka hoʻopili pololei ma waena o ka mea hana a me ka mea hana.ʻO ka hopena, he liʻiliʻi ka lole o ka mea hana, e alakaʻi ana i ka lōʻihi o ke ola mea hana a hoʻemi ʻia nā kumukūʻai mālama.
Hōʻuluʻulu manaʻo
Hōʻike nui kēiaʻatikala i ke kaʻina hana EDM i ke kaʻina hana mold,ʻaʻole wale i ka hoʻokomoʻana i kāna kahe kaʻina hana, akā, hoʻokomo pū i nā pono nui o kēia kaʻina hana.Ma o ka wikiō i luna, manaʻo wau e hiki iā ʻoe ke hoʻomaopopo i ke kaʻina hana me ka maopopo.Inā he mau nīnau ʻē aʻe kāu, e ʻoluʻolu e ʻoluʻolukāhea iā mā˚ou.
