Indlela yokugqibela yeebhasi zeCopper: Kutheni i-Diffusion Welding iba lolona Khetho luPhakamileyo{0}}Isiphelo seMveliso

Xa usiva "ibhasi yebhasi eguquguqukayo," unokuba nomfanekiso wecandelo elilula lokuqhuba. Nangona kunjalo, kwiindawo ezibalelayo ezifana nezithuthi zombane, izixokelelwano zokugcina amandla ebhetri, kunye{1}}neziko ledatha yokusebenza ephezulu, elicandelo lithobekileyo lifumana inguqu enzulu kwezobuchwephesha. Iindlela zesiNtu ezifana nokubrawuza kunye ne-welding yoxinzelelo ziyatshintshwa ngokuthe ngcembe yinkqubo yokusika{3}}:Umatshini wokuwelda weDiffusion.

Olu ayilophuculo nje; kukutsiba okulinganayo. Ukuphuculwa kwentsebenzo enikezelayo akukho nto iphazamisayo. Eli nqaku liza kubonelela ngokuntywila nzulu ekubeni kutheni i-welding ye-diffusion imele eyona fomu yeebhasi zobhedu kwaye, okona kubaluleke kakhulu, ibonelela ngesikhokelo sokuthenga esineenkcukacha sokukunceda wenze esona sigqibo silumkileyo kweliza lobuchwepheshe.

Kumashumi eminyaka, ibrazing kunye noxinzelelo welding ibikuhambo-kwiindlela zokwenza iibhasi zebhasi eziguqukayo. Amaxabiso aphantsi- kwaye asekelwe kwiinkqubo zabantu abadala. Nangona kunjalo, iziphene zabo zendalo ziye zaba yimiqobo engamkelekanga kusetyenziso lwanamhlanje olukhulayo- oluqhutywa kwizicelo.

Ukubrawuza kufana nokusebenzisa "iglu" yesinyithi etyhidiweyo (intsimbi yokuzalisa) ukudibanisa iileya zefoyile yobhedu. Ngelixa ifanelekile, le ndlela idala ubuthathaka obuthathu:

1. "Indawo eshushu" yoKuxhathisa okuPhezulu:Esi sesona siphene sibulalayo sebrazing. Ubhedu olusulungekileyo lunoxhathiso lombane olusezantsi kakhulu (malunga. 1.75 x 10⁻⁸ Ω·m). Ngokwahlukileyo, iintsimbi eziqhelekileyo zokugcwalisa njengesilivere okanye i-tin{4}}i-alloys esekwe kwi-alloys zinokuxhathisa aliqela, okanye amaxesha amaninzi, ngaphezulu. Oku kufana nokubeka i-toll booth exineneyo kuhola wendlela ovulekileyo{6}. Xa umsinga ophezulu udlula, le "toll booth" ivelisa ubushushu obubonakalayo ngenxa yokumelana kwayo okuphezulu. Idatha ibonisa ukuba phantsi komthwalo ofanayo wangoku, ukunyuka kweqondo lobushushu kwindawo edibeneyo yebrazed ingaba ngama-30{10}}50% ngaphezulu kokusasazwa{12}}kwenye edityanisiweyo. Oku akuchithi nje amandla axabisekileyo kodwa kubangela ingozi enkulu yomlilo kwizicelo zombane ophezulu.
2. IsiNxulumanisi seBond esingathembekanga:Kwinqanaba le-microscopic, i-interface phakathi kwentsimbi yokuzalisa kunye neefoyile zethusi zihlala zigcwele i-voids kunye neendawo zokudibanisa okungaphelelanga, ezaziwa ngokuba "ziindawo ezibandayo." Ezi ziphene, njenge-osteoporosis ethanjeni, ziwenza buthathaka kakhulu amandla omatshini woqhagamshelwano, zenza ukuba kube lula ukudinwa kunye nokwaphuka phantsi{1}}kokungcangcazela kwexesha elide okanye ibhayisekile eshushu.
3. "Unxulumano olubuthathaka" loKuxhathisa amaqondo aphantsi:Indawo yokunyibilika yezinyibilikisi zesinyithi ingaphantsi kakhulu kunokopolo (umzekelo, ezinye ii-tin{2}}izidayisi ezisekwe zinyibilika malunga ne-200℃/ 392℃F). Kwimeko yesiphaluka esifutshane okanye ukugqithiswa, ukushisa okuphezulu ngokukhawuleza kunokwanela ukunyibilikisa umdibaniso, okukhokelela ekungaphumeleli koxhulumaniso kunye nemiphumo eyintlekele.

Uxinzelelo lwe-welding luyayiyeka "iglu," ukuzama ukuhlanganisa ngenkani iifoyile zobhedu kunye kusetyenziswa uxinzelelo olukhulu lomatshini. Nangona le ndlela igwema ukungenisa ukungcola, umgangatho webhondi ufana nephepha elixinzelelwe ngokuqinileyo kunento enye, eqinileyo.

1. "I-Chasm" yeMikroskopu yeZikhewu:Nangona ibonakala iqinile ngokwe-macroscopically, kwisikali se-atom, izithuba ezingenakubalwa ze-microscopic zihlala phakathi kweefoyile zobhedu. Njengoko ngoku ujikeleza kwezi zithuba, indlela yayo iba yingcungcutheko, kwaye indawo esebenzayo yokuqhuba incinci kakhulu kunexabiso lethiyori, okukhokelela ekuxhathiseni okuthe gqolo.
2. "Ibhombu yexesha" yoxinzelelo lwangaphakathi:Uxinzelelo olukhulu ludala inani elikhulu loxinzelelo olushiyekileyo ngaphakathi kwendawo yokusebenza. Oku kwenza ukuba icandelo libe "brittle" kwaye livakale kakhulu kwiiyantlukwano zoxinzelelo. Ngokuhamba kwexesha, umngcipheko wokuqhekeka uyanda kakhulu.

Ukuthotywa okuninzi kweendlela zemveli kuye kwanyanzela ishishini ukuba lifune isisombululo esigqibeleleyo esilungisa ingxaki kwiingcambu zayo.

Itekhnoloji ye-welding ye-Diffusion ishiya ngokupheleleyo i-paradigms endala "yokunyibilika" kunye "nobuqhetseba". Isebenza kwindawo eqinileyo, ivumela iiathom zobhedu ngokwazo ukuba "zikhule" kunye.

• Yiba nomfanekiso ucinezela iibhloko ezimbini zomthi ezicocekileyo nezisicaba kunye namandla amakhulu. Emva koko, usebenzisa ubushushu obuthambileyo ngelixa ugcina olo xinzelelo. Emva kwethuba, iimolekyuli ezikumphezulu webhloko nganye ziqalisa ukudibana zize zityhutyhe enye kwenye. Ekugqibeleni, i-interface yoqhagamshelwano iyanyamalala ngokupheleleyo, kwaye "ikhula" ibe yinto enye, eqinile.
• Le yindlela kanye i-diffusion welding esebenza ngayo. Kwi-vacuum okanye kwi-atmosphere ekhuselayo, ubushushu obulawulwa ngokuchanekileyo, uxinzelelo, kunye nexesha lisetyenziswa ukwenza ii-athomu zobhedu zisebenze. Oku kubanika ixesha kunye namandla okufuduka ngaphaya kojongano lokuqala kwaye basasazeke kwinqwanqwa yekristale yomnye, ekugqibeleni benze ulwakhiwo lweenkozo olufana nemathiriyeli yomzali.

• Kufuphi{0}}Zero Ukuchasa isiNxulumanisi:Ngokufezekisa ibhondi yentsimbi yokwenyani kwinqanaba leathom, i-microstructure yendawo edityanisiweyo iye ingabonakali kubhedu olusulungekileyo. Uvavanyo olugunyazisiweyo lubonisa ukuba ukuxhathisa kombane kwediffusion{1}}ijoyinti elidityanisiweyo linokugqithisa i-98% yemathiriyeli yobhedu engumzali, iyenza ilingane nebha eqinileyo. Oku kuguqulela elona lahleko lisezantsi linokwenzeka kunye nokuveliswa kobushushu obuncinci.
• Amandla oomatshini abodlula iMathiriyeli yoMzali:I-Diffusion welding isusa zonke iziphene zojongano. Amandla ayo okudityaniswa, ukomelela okuqinileyo, kunye nobomi bokudinwa bunokude bube ngaphezu kobo besixhobo sobhedu esifakwe ngumzali. Ubume bayo be-monolithic buvumela ukuba ihlale yomelele naphantsi kweyona ntshukumo inzima kunye neemeko zempembelelo.
• Ukuthembeka okungenakulinganiswa kunye nexesha lokuphila:Ngaphandle -kwenqanaba lokunyibilika-kwentsimbi yesithako esisezantsi, ukuxhathisa kwayo{2}}ubushushu obuphezulu kuyafana nobhedu olusulungekileyo (indawo yokunyibilika 1083℃/ 1981℃F), ngokusisiseko isusa umngcipheko wokunyibilika ngexesha leziganeko zokugcwala. Ngaphaya koko, ulwakhiwo olushinyeneyo lweathom lubonelela ngokugqwesa ukuxhathisa kwi-oxidation kunye nokubola, iqinisekisa ukusebenza okuzinzileyo kuwo wonke umjikelo wobomi bemveliso.

Nje ukuba uqaphele ixabiso elikhulu le-welding yokusasazwa, ukukhetha izixhobo ezifanelekileyo kuba sisitshixo sempumelelo. Olu ayilotyalo-mali nje; kukuzibophelela kumgangatho wexesha elizayo weemveliso zakho. Sebenzisa olu luhlu lulandelayo ukukhokela uvavanyo lwakho.
