Nangona kunjalo, abavelisi abaninzi bahlangabezana nokuphazamiseka okuqhelekileyo: ukusebenza ngokubambisana okungaphumeleli ukuhlangabezana neenkcukacha. Amaxesha amaninzi, umba ayingomatshini ngokwawo, kodwa kukunqongophala kolawulo "kwimeko{8}}yangaphambili"{9}}ngokukodwa ukucoceka kwayo kunye nobume bomphezulu.
Kwesi sikhokelo, siza kuthatha idive enzulu ukusuka kumbono wenjineli yenkqubo ephezulu ukuhlalutya iimfuno ezingqongqo zemathiriyeli yobhedu kunye nokubonelela ngesakhelo esisebenzayo sokukhetha ausasazo welding machine. Injongo yethu kukukunceda uqinisekise umgangatho ovela kumthombo kunye nokwandisa ixabiso lotyalo-mali lwakho.
Ukucoceka kobhedu: Isiseko se-Weld Integrity
Impumelelo yokusasazwa kwe-welding ixhomekeke ekudibaneni komthungo kwee-athomu phantsi kobushushu obuphezulu kunye noxinzelelo. Nakuphi na ukungcola okuthintela oku kufuduka kweathom ngokuqinisekileyo kuya kukhokelela kwiziphene ezifihlakeleyo kwilungu.
Umxholo we-Oxygen: "Iintshaba zikawonke-wonke iNombolo enye"
Xa ukhetha ubhedu, sicebisa ngamandla iOxygen{0}}I-Copper yaMahla (OFC, efana neC10100 okanye iC10200). Ubhedu oluqhelekileyo lwe-electrolytic tough pitch copper iqulethe umkhondo weoksijini enokuthi ibangele ukusilela kwintlekele ngexesha lobushushu obuphezulu{4} benkqubo yokusasazwa:
- Umngcipheko we "Hydrogen Embrittlement":Ukuba umkhondo we-hydrogen ukhona kwindawo ye-welding okanye izinto ngokwazo, amaqondo obushushu aphezulu abangela ukuba i-hydrogen isabele nge-cuprous oxide (Cu₂O) ngaphakathi kobhedu. Le ntshukumo yenza{1}}umphunga wamanzi woxinzelelo oluphezulu (H₂O). Kuba umphunga awukwazi ukubaleka i-matrix yobhedu eshinyeneyo, yenza i-microscopic voids kwimida yeenkozo, ekhokelela kwi-embrittlement enzima kunye nokwehla okubukhali kumandla okwakhiwa{3}}into eyaziwayo kwishishini njenge "isifo se-hydrogen."
- Izithintelo zefilimu ye-Oxide:Nangaphandle kwe-hydrogen embrittlement, umxholo ophezulu weoksijini wenza umphezulu wobhedu uthande ukwenza ifilimu eshinyeneyo, ezinzileyo yeoxide. Le filimu isebenza njengesithintelo somzimba ekusasazweni kwe-athomu, ukuthintela ukudibana ngokuthe ngqo kunye nokunyibilika phakathi kweendawo zokukhwelana. Isiphumo sisizinga esiphantsi sokubambisana kunye nokungahambi kakuhle kombane.
Kwizicelo ezifuna i-conductivity ephezulu kunye nokutywinwa kwe-hermetic, umxholo we-oxygen kufuneka ugcinwe ngaphantsi kwe-0.001%, kunye nokuhlanjululwa kobhedu ubuncinane be-99.95%.
Imida engqongqo kwiZinto ezingacocekanga
Ngaphaya kweoksijini, okunye -ukungcola{1}}kwendawo enyibilikayo esezantsi njengeBismuth (Bi) kunye neLead (Pb) kufuneka ilawulwe ngokungqongqo. Kubushushu obuqhelekileyo be-welding ye-diffusion (ngokuqhelekileyo ngu-0.6 ukuya ku-0.8 ukuphinda-phinda indawo yokunyibilika kobhedu), ezi elementi zikholisa ukwahlula kwimida yengqolowa, zenza ulwelo okanye amanqanaba asezantsi{5}}anyibilika{6}}. Olu lwahlulo lwenza buthathaka kakhulu umda wokutya okuziinkozo, okubangela ukuncipha okutshisayo (ukuqina) ngexesha lokupholisa okanye ngelixa ukwinkonzo. Ukukhetha phezulu{9}}kobhedu olusulungekileyo kuphela kwendlela yokuphelisa obu kungcola bunobungozi kumthombo.
Unyango loMphezulu: Ukuqinisekisa "Zero-Umgama" uQhagamshelwano lweAtom
Ukuba ukucoceka kwezinto eziphathekayo "yimpilo yangaphakathi" ye-weld, unyango olungaphezulu "luqeqesho lwangaphandle." I-welding ye-diffusion ifuna imiphezulu yokukhwelana ukuba ibe tyaba ngokupheleleyo kwaye icoceke kumgangatho wemicroscopic.
Ukulinganisa Uburhabaxa boMphezulu
Uburhabaxa bomphezulu yeyona metric yokuqala yokucaba. Kwi-welding ye-diffusion, imisela ngokuthe ngqo indawo yoqhagamshelwano yokuqala kunye nobunzima bokuvala i-voids microscopic interface.
| Imeko yesicelo | Uburhabaxa obuCetyisiweyo | Impembelelo engundoqo |
| IBanga loShishino (umzekelo, iibhasi ezisemgangathweni) | Ra <0.8 μm | Uqinisekisa izinga lokudibanisa okusisiseko kunye nokunciphisa uxinzelelo olufunekayo. |
| Phezulu-Ukuchaneka (umzekelo, ivacuum seals, iitsinki zobushushu) | Ra 0.1 μm - 0.2 μm | Ukuphumeza ubuninzi be-hermeticity kunye ne-conductivity ngokunciphisa izithuba zojongano. |
Okukhona uburhabaxa busezantsi, kokukhona imiphezulu ingena lula kwi-deformation yeplastiki xa kufakwa uxinzelelo. Oku kuvala ngokukhawuleza izitenxo zemicroscopic, kucutha umgama kunye nexesha elifunekayo ukuze iiathom zisasazeke kujongano.
