I-aluminium alloy engu-6061 yaziwa kabanzi njenge-versatileI-aluminium eyenziwe ngochungechunge lwe-6000Abathengi abaningi bacabanga ukuthi ibanga lezimboni 6061 lingasebenzela ngqo izimo zokukhiqiza ama-semiconductor. Kodwa-ke igebe phakathi kwe-industrial 6061 evamile kanye nebanga le-semiconductor 6061 akuyona indaba elula yokusebenzisa. Kuncike ezingozini zokuthembeka ezinquma ukuthi abakhiqizi bayalinge yini ukusebenzisa izinto kuhadiwe ye-semiconductor enembile.

Amaphutha amancane ezingxenyeni ze-aluminium zemishini ye-semiconductor awabangeli ukwehluleka okusheshayo. Uma evezwa ezindaweni ezihlala isikhathi eside ze-vacuum kanye negesi egqwalisayo ngemijikelezo yokusebenza ende, lawa maphutha amancane ayanda kancane kancane. Imiphumela ibonakala njengokuphambuka kwezingxenye, i-oxidation engavamile kanye nokwehluleka kokugqwala ekugcineni. Ucwaningo lwamuva lwezinto ezibonakalayo luqinisekisa ukuthi umehluko oyinhloko awukho ekuqanjweni kwe-alloy uqobo. Luvela ekulawuleni okunembile kwesakhiwo se-microstructure kanye nezinqubo zokukhiqiza, ikakhulukazi usayizi kanye nokusatshalaliswa kwezinhlayiya zesigaba sesibili, okungukuthi i-Al₁₅(Fe,Mn)₃Si₂. Lesi sici silawula ngqo ukuzinza kokugqwala kwe-alloy. Ngisho nangebanga elifanayo le-6061, izinhlobo zezimboni kanye nezinhlobo ezichazwe yi-semiconductor empeleni zingezinhlelo ezimbili zokusebenza ezihlukile.

Ibanga le-semiconductor 6061 lidlula ezithuthukweni ezinhlanu ezinkulu ezihlelekile uma kuqhathaniswa ne-standard industrial 6061.

Okokuqala kuza ukucwengwa okuphezulu kobumsulwa, kusuka ekuhambisaneni okuyisisekelo kokwakheka kuya ekulawulweni okuqinile kokungcola. Ihadiwe ye-semiconductor ibeka imingcele eqinile ekukhishweni kwegesi kwezinto, ukungcola kwe-ionic kanye nokuzwela kokugqwala. Abakhiqizi kumele banciphise ububanzi bokuguquguquka kokuqukethwe kwe-Fe, Si kanye ne-Cu. Ngenkathi i-6061 evamile ivumela okuqukethwe kwethusi okusukela ku-0.15% kuya ku-0.4%, izinto ze-semiconductor-grade zivala lesi sici ngaphakathi kwebhande eliqinile ukuze kuncishiswe izingozi zokugqwala kwe-electrochemical. Inhloso yokwenza ngcono okuyinhloko ukucwenga nokusabalalisa izinhlayiya zesigaba sesibili ze-Al₁₅(Fe,Mn)₃Si₂ ezimangelengele.

Ukubonwa kwe-Metallographic kukhombisa izimo ezahlukahlukene zalesi sigaba se-intermetallic. I-acicular β-Al₅FeSi yenza kabi kakhulu, ithambekele ekuqhekekeni, ekugqwaleni nasekuphazamisekeni kwe-oxidation. I-blocky primary α-Al(Mn,Fe)Si inikeza ingozi encishisiwe kodwa engazinzile. Isigaba se-α esihle nesihlakazekile sinikeza ukusebenza okulinganiselayo nokusebenza okulinganayo. Isigaba se-α "esinomumo womlingiswa waseShayina" esihle kakhulu sibonisa imiphetho eyindilinga engenamakhona abukhali, okufeza ukuzinza okuphezulu kakhulu kanye nokumelana nokugqwala.

Okwesibili, ukwelashwa kokushisa kwenziwa ngokwezifiso kunokuthi kusetshenziswe izindlela zokupheka ezijwayelekile. I-T6 evamile yokushisa ejwayelekile ye-6061 isebenzisa izixazululo ezijwayelekile kanye nemingcele yokuguga. Izinto zezinga le-semiconductor zidinga amashejuli okushisa aklanyelwe wena. Isebenzisa izinga lokushisa lesisombululo elingu-540 ~ 550 °C, cishe elingu-20 °C ngaphezu kwe-T6 evamile, ukuze kube lula ukuncibilika ngokuphelele kwama-precipitates e-Mg₂Si. Isikhathi sokubamba sigcinwa amahora ama-2, sihambisana nokucima okuhleliwe noma okusheshayo ukuze kuthuthukiswe ukusebenza okuyinhloko kwamapuleti aminyene. Inqubo yokuguga ilungiswa ibe ngu-170 °C amahora ayi-12, ilinganisela amandla omshini kanye nezakhiwo ze-anodizing.

Okwesithathu, ukukhululeka ekucindezelekeni kwangaphakathi kuba inqubo ephoqelekile esikhundleni sesinyathelo sokuzikhethela. I-aluminiyamu ejwayelekile ye-T6 igcina ukucindezeleka kwangaphakathi okusele, okubangela ukugoba okuqhubekayongesikhathi sokucubungula i-CNC ngokunemba. I-semiconductor-grade 6061 iqinisa ukuqina kwe-T651. Izinto zidlula ekunwebekeni okungapheli okungu-1% kuya ku-3% ngaphambi kokuguga okwenziwe ukuze kususwe ukucindezeleka okusele okungaphezu kuka-90%. Ukunwebeka okwengeziwe noma ukuqondisa ukucindezela kufakwa kumapuleti aqinile, okuqinisekisa ukubekezelelana kokusicaba okungu-≤0.02 mm ezingxenyeni ezinkulu ezenziwe ngomshini.

Okwesine, isakhiwo esincane silawulwa kahle ukuze kube nekhwalithi efanayo. Izinhlayiya zesigaba sesibili ezinkulu kakhulu zisebenza njengezindawo zokuqala zokugqwala kanye namaphuzu okukhubazeka kwamafilimu afakwe i-anod. Ukuqondiswa kwezinhlayiya ze-α-Al₁₅(Mn,Fe)₃Si₂ kumele kuphathwe ngokucophelela. Izinhlayiya eziqondiswe ngqo phezulu zakha ama-longitudinal pores ngesikhathi se-anodization, okuvumela imidiya egqwalisayo ukuthi ingene ngaphansi kwe-aluminium substrate futhi inciphise kakhulu ukumelana nokugqwala. Usayizi wezinhlayiya ezifakwe i-crystal ubuye uqashwe ngokuqinile ukuze kugwenywe ukugoba kwezinhlayiya kanye nokukhubazeka kwama-speckle anodized.

Okwesihlanu, ukusebenza kwe-anodizing kuyalinganiswa futhi kuqinisekiswe. I-coating eqinile ye-anodized ku-aluminium ye-semiconductor kumele ihlangabezane nezilinganiso eziqinile zokwamukelwa. Kufanele imelane okungenani amahora ama-4 okuchayeka ku-5% hydrochloric acid, idlule kakhulu isikhathi samahora ama-2 ~ 3 se-T6 6061 evamile. I-voltage yokuqhekeka ifinyelela ku-≥640 V.DC/mil, kanti ubulukhuni be-oxide coating budlula u-400 HV0.1. Isakhiwo se-coating sinezimbobo ezinde eziqondile kanye nesendlalelo esiqinile ngokuphelele.

Imephu yobuchwepheshe ephelele yebanga le-semiconductor 6061 ilandela ukulandelana okucacile: ukulawulwa kokwakheka okuhlanzekile okuphezulu, ukwelashwa kokushisa okwenziwe ngokwezifiso kusisombululo esingu-540~550°C kanye nokuguga okungu-170°C, ukukhululeka kokucindezeleka kwe-T651 okuphoqelekile, isakhiwo esincane esicwengisisiwe nesihlakazeke ngokulinganayo, kanye nokusebenza okuqinisekisiwe kwe-anodizing ngezinkomba zokugqwala kanye ne-dielectric ezifanele.

Abakhiqizi basekhaya manje sebefinyelele umthamo wokukhiqiza ngobuningi bepuleti le-aluminium lebanga le-semiconductor 6061. Izinto ze-aluminium zekhwalithi ephezulu zemishini ye-semiconductor ziphula ukuthembela kwesikhathi eside ekungeniseni ngokuqamba okusha kwendawo. Kubalulekile ukuqaphela ukuthi ukuthuthukisa i-6061 evamile ibe yizinto ezifanelekile ze-semiconductor akugcini nje ngokushintsha uphawu noma ukwengeza isinyathelo esisodwa sokucubungula. Kudinga ukulungiswa kweketanga eligcwele elihlanganisa ukwakheka kwamakhemikhali, ukucubungula ukushisa, ukuphathwa kokucindezeleka, ukulawulwa kwesakhiwo esincane kanye nokuqinisekiswa kwe-anodizing. Ngaphandle kwezitifiketi zokuhlola ezisemthethweni zokusekela izilinganiso zokusebenza, i-aluminium ebizwa ngokuthi “ibanga le-semiconductor” ingase ihlanganiswe kabusha nje ibe yisitokwe sezinga lezimboni.

Inkampani yethu inikeza ibanga le-semiconductor elifanelekileAmapuleti e-aluminium angu-6061 eceleniAmapuleti e-aluminium ajwayelekile ezimboni angu-6061, asekela ukusika ngokunemba kanye nomshini we-CNC owenziwe ngokwezifiso. Uma ufuna izikhala ze-aluminium ezizinzile nezilandelekayo zemishini ye-semiconductor, izingxenye ze-vacuum kanye nezingxenye zesakhiwo ezinembile, singakunikeza imibiko yokuhlola izinto eziqinisekisiwe ukuze ifane nemininingwane yakho eqinile yokukhiqiza.
