I-aluminium alloy ye-6061 yaziwa ngokubanzi njengesixhobo esinokusetyenziswa ngeendlela ezahlukeneyoI-aluminium eyenziwe ngothotho lwe-6000Abathengi abaninzi bacinga ukuba i-industrial grade 6061 inganceda ngqo kwiimeko zokwenziwa kwee-semiconductor. Kodwa umsantsa phakathi kwe-industrial 6061 eqhelekileyo kunye ne-semiconductor grade 6061 ayisiyonto ilula ukuyisebenzisa. Ixhomekeke kwiingozi zokuthembeka ezigqiba ukuba abavelisi baya kuba nesibindi sokufaka ezi zinto kwi-hardware ye-semiconductor echanekileyo.

Iziphene zeMicroscopic kwizixhobo ze-aluminium zezixhobo ze-semiconductor azibangeli ukusilela ngoko nangoko. Xa zibonakaliswa kwindawo ehlala ihleli ye-vacuum kunye negesi erhabaxa kwixesha elide lokusebenza, ezi ziphene zincinci ziyanda kancinci kancinci. Iziphumo zibonakala njengokuphambuka kwecandelo, i-oxidation engaqhelekanga kunye nokusilela kokugqwala ekugqibeleni. Uphando lwakutshanje lwezinto ezibonakalayo luqinisekisa ukuba umahluko ophambili awukho kwigama le-alloy ngokwalo. Ivela kulawulo oluchanekileyo lwe-microstructure kunye neenkqubo zokuvelisa, ingakumbi ubungakanani kunye nokusasazwa kwamasuntswana esigaba sesibini, oko kukuthi i-Al₁₅(Fe,Mn)₃Si₂. Olu phawu lulawula ngokuthe ngqo uzinzo lokugqwala kwe-alloy. Nangona inqanaba elifanayo le-6061, iinguqulelo zoshishino kunye neentlobo ezichazwe yi-semiconductor ngokusisiseko zezeenkqubo ezimbini zokusebenza ezahlukeneyo.

Ibanga le-semiconductor 6061 liphantsi kohlaziyo oluhlanu olukhulu olucwangcisiweyo xa lithelekiswa ne-standard industrial 6061.

Okokuqala kuza ukuphuculwa kobunyulu obuphezulu, ukusuka ekuthobeleni ulwakhiwo olusisiseko ukuya kulawulo olungqongqo lokungcola. Izixhobo ze-semiconductor zibeka imida enzima ekukhutshweni kwegesi kwizinto, ungcoliseko lwe-ionic kunye nokuchaphazeleka kokugqwala. Abavelisi kufuneka banciphise uluhlu lokuguquguquka komxholo we-Fe, Si kunye ne-Cu. Ngelixa i-6061 eqhelekileyo ivumela umxholo wobhedu ukusuka kwi-0.15% ukuya kwi-0.4%, izinto ze-semiconductor-grade zitshixa le nto ngaphakathi kwebhendi eqinileyo ukunciphisa umngcipheko wokugqwala kwe-electrochemical. Injongo ephambili yokwenza ngcono kukucoca nokusasaza amaqhekeza e-Al₁₅(Fe,Mn)₃Si₂ e-coarse phase.

Uqwalaselo lweMetallographic lubonisa iindlela ezahlukeneyo zokwakheka kwesi sigaba se-intermetallic. I-acicular β-Al₅FeSi yenza kakubi kakhulu, ithambekele ekuqhekekeni, ekugqwaleni nasekufakweni kwe-oxidation. I-blocky primary α-Al(Mn,Fe)Si inika umngcipheko onciphileyo kodwa ongagungqiyo. I-fine and dispersed α-phase inika ukusebenza okulinganayo kunye nokusebenza okulinganayo. I-α-phase efanelekileyo "emile okwesiTshayina" inemiphetho ejikelezileyo engenamakona abukhali, ifikelela kukuqina okuphezulu kunye nokumelana nokugqwala.

Okwesibini, unyango lobushushu lwenziwa ngokwezifiso endaweni yokusebenzisa iiresiphi eziqhelekileyo. Ubushushu obuqhelekileyo be-T6 kwi-6061 eqhelekileyo busebenzisa isisombululo esiqhelekileyo kunye neeparameter zokuguga. Izinto zenqanaba le-semiconductor zifuna iishedyuli zobushushu ezilungiselelweyo. Zisebenzisa ubushushu besisombululo obuyi-540 ~ 550 °C, malunga nama-20 °C ngaphezulu kune-T6 eqhelekileyo, ukuze kube lula ukunyibilika ngokupheleleyo kwe-Mg₂Si precipitates. Ubude bokugcina bugcinwa iiyure ezi-2, budibene nokucima okucwangcisiweyo okanye okukhawulezayo ukuphucula ukusebenza okuphambili kweepleyiti ezityebileyo. Inkqubo yokuguga ilungiswa ukuya kwi-170 °C iiyure ezili-12, ilinganisela amandla oomatshini kunye neempawu ze-anodizing.

Okwesithathu, ukukhululeka koxinzelelo lwangaphakathi kuba yinkqubo enyanzelekileyo endaweni yokuba yinyathelo lokuzikhethela. I-aluminiyam ye-T6 eqhelekileyo igcina uxinzelelo lwangaphakathi olusele, olubangela ukugoba okuqhubekayongexesha lokuchonga ngokuchanekileyo i-CNC. I-semiconductor-grade 6061 iqinisekisa ubushushu be-T651. Le nto idlula kwi-1% ukuya kwi-3% yolusu oluhlala luhleli ngaphambi kokuba iguge ngokwenziwa ukuze kususwe uxinzelelo olungaphezulu kwe-90% olushiyekileyo. Ukolula okongezelelweyo okanye ukuqiniswa koxinzelelo kufakwa kwiipleyiti ezingqindilili, ukuqinisekisa ukunyamezelana kokuthe tyaba ≤0.02 mm kwiindawo ezinkulu ezenziwe ngomatshini.

Okwesine, isakhiwo se-microstructure silawulwa kakuhle ukuze kubekho umgangatho ohambelanayo. Amasuntswana esigaba sesibini amakhulu asebenza njengeendawo zokuqala zokugqwala kunye neendawo ezingalunganga kwiifilimu ezifakwe i-anod. Indlela ezibekwe ngayo iinkozo ze-α-Al₁₅(Mn,Fe)₃Si₂ kufuneka zilawulwe ngononophelo. Iinkozo ezibekwe ngokuthe nkqo zenza ii-longitudinal pores ngexesha lokugqwala, okuvumela i-corrosive media ukuba ingene kwi-aluminium substrate kwaye inciphise kakhulu ukumelana nokugqwala. Ubungakanani beenkozo ezifakwe i-recrystallised bujongwa kakhulu ukuze kuthintelwe ukugqwala kweenkozo kunye neziphene ze-anodizing speckle.

Okwesihlanu, ukusebenza kwe-anodizing kuyalinganiswa kwaye kuqinisekiswe. I-coating eqinileyo kwi-aluminium ye-semiconductor kufuneka ihlangabezane nemilinganiselo engqongqo yokwamkelwa. Kufuneka imelane ubuncinane iiyure ezi-4 zokuvezwa kwi-5% ye-hydrochloric acid, idlule kakhulu ukunyamezela kweeyure ezi-2 ~ 3 ze-T6 6061 eqhelekileyo. I-voltage yokuqhekeka ifikelela kwi-≥640 V.DC/mil, kwaye ubunzima obuncinci be-oxide coating budlula i-400 HV0.1. Isakhiwo se-coating sinee-pores ezinde ezithe nkqo kunye nomaleko oxineneyo ngokupheleleyo.

Isicwangciso esipheleleyo sobuchwephesha se-semiconductor-grade 6061 silandela ulandelelwano olucacileyo: ulawulo lokwakheka kobunyulu obuphezulu, unyango lobushushu olulungiselelwe wena kwisisombululo se-540 ~ 550 °C kunye nokuguga kwe-170 °C, ukukhululeka koxinzelelo lwe-T651 oluyimfuneko, isakhiwo se-microstructure esicociweyo nesisasazeke ngokulinganayo, kunye nokusebenza okuqinisekisiweyo kwe-anodizing ngezibonakaliso zokubola ezifanelekileyo kunye ne-dielectric.

Abavelisi basekhaya ngoku bafikelele kumthamo omkhulu wemveliso yepleyiti ye-aluminium ye-semiconductor grade 6061. Izixhobo ze-aluminium eziphezulu zezixhobo ze-semiconductor ziyaphula ukuthembela kokungenisa ixesha elide ngokuvelisa izinto ezintsha zasekuhlaleni. Kubalulekile ukuqaphela ukuba ukuphucula i-6061 eqhelekileyo ibe zizinto ezifanelekileyo ze-semiconductor akukokutshintsha nje uphawu okanye ukongeza inyathelo elinye lokucubungula. Ifuna ukulungiswa kwe-full-chain equka ukwenziwa kweekhemikhali, ukucubungula ubushushu, ulawulo loxinzelelo, ukulawulwa kwe-microstructure kunye nokuqinisekiswa kwe-anodizing. Ngaphandle kwezatifikethi zokuhlola ezisemthethweni zokuxhasa imilinganiselo yokusebenza, i-aluminium ebizwa ngokuba yi-"semiconductor grade" inokuba yisitokhwe se-industrial grade esipakishwe kwakhona.

Inkampani yethu inika umgangatho we-semiconductor ofanelekileyoIipleyiti ze-aluminium ezingama-6061 ecaleniIipleyiti ze-aluminium zemizi-mveliso ze-6061 eziqhelekileyo, ezixhasa ukusika ngokuchanekileyo kunye nomatshini we-CNC owenziwe ngokwezifiso. Ukuba ufuna iiblanks ze-aluminium ezizinzileyo nezilandelekayo zezixhobo ze-semiconductor, izinto ze-vacuum kunye neendawo zesakhiwo ezichanekileyo, singakunika iingxelo zovavanyo lwezinto eziqinisekisiweyo ukuze zihambelane neenkcukacha zakho ezingqongqo zokuvelisa.
