Ngophuhliso oluqhubekayo lweenkqubo ezingangenisi kakhulu, izixhobo zonyango ezifakelwayo, izixhobo zotyando, kunye nezixhobo zonyango ezichanekileyo, iimfuno zokusebenza komphezulu ziya ziba nzima ngakumbi. Izixhobo zezixhobo zonyango akufuneki zihlangabezane kuphela neemfuno zokuchaneka kunye nokuhambelana kwezinto eziphilayo, kodwa zinokufuna nokuphuculwa kokuxhathisa ukuguguleka, ukumelana nokugqwala, ukuthambisa, ubulukhuni, kunye nokuzinza komphezulu ngokusebenzisa ubuchwepheshe obuphambili bokugquma.
Xa kuthelekiswa nezicelo zokuhombisa, ii-coating ezisebenzayo zezixhobo zonyango zigxininisa kakhulu ekusebenzeni kwe-coating, ukuphindaphinda kwenkqubo, ukuhambelana kwe-substrate, kunye nokulandeleka kwemveliso. Ke ngoko, ukukhetha izixhobo ezifanelekileyo zokuhombisa nge-vacuum akuyonto nje yokukhetha umatshini omkhulu okanye osebenza kakhulu. Ifuna ukufanisa uqwalaselo lwezixhobo nezinto ze-substrate, i-geometry yecandelo, inkqubo yokuhombisa, ukusebenza okujoliswe kuko, kunye namandla emveliso.
Ukwambathisa izixhobo zonyango kuqhutywa ziimfuno zomsebenzi
Izixhobo zonyango zenziwe ngezinto ezahlukeneyo, kuquka intsimbi engatyiwayo, i-titanium alloys, i-cobalt-chromium alloys, iplastiki yobunjineli, kunye nezinye izinto ezikhethekileyo. Ii-substrates ezahlukeneyo zineempawu ezahlukeneyo zobushushu, iimeko zomphezulu, kunye neemfuno zokunyangwa kwangaphambili kunye nokunamathela kwengubo.
Kwizixhobo zotyando kunye nezixhobo zonyango ezichanekileyo, izinto eziqinileyo ezifana neTiN, TiCN, TiAlN, kunye neCrN zinokuqwalaselwa apho kufuneka khona ukumelana nokuguguleka okuphuculweyo, ubulukhuni bomphezulu, kunye nokuzinza kweekhemikhali. Kwizinto apho ukusebenza kokungqubana kunye nokutyibilika kubaluleke kakhulu, izinto ezixineneyo ezifana neDLC (Diamond-Like Carbon) zinokuqwalaselwa ukunciphisa ukungqubana kunye nokuphucula ukuqina komphezulu.
Inkqubo yokugquma kufuneka ke ngoko iphuhliswe malunga nokusetyenziswa kwayo endaweni yezinto zokugquma zodwa. Ukulungiswa kwe-substrate, ukucocwa kwe-plasma, ukugrumba ii-ion, uyilo lwe-interlayer, ukufakwa kwe-coating, kunye nonyango emva konyango zonke ezi zinto zinefuthe ekusebenzeni kokugqibela kwe-coating.
Iijometri ezintsonkothileyo zidala iimfuno eziphezulu zokuziqhelanisa nezixhobo
Izixhobo zezixhobo zonyango zihlala zibonakaliswa ziimilinganiselo ezincinci, iijometri ezintsonkothileyo ezinemilinganiselo emithathu, imingxunya enzulu, imingxunya emincinci, imiphetho ebukhali, kunye neendawo ezisebenzayo ezineemfuno ezahlukeneyo zokugquma. Ezi mpawu zesakhiwo zichaphazela ngokuthe ngqo ukufikeleleka kokugquma kunye nokusasazwa kobukhulu.
Kwiinkqubo zokubeka umgca wokubona, ezifana nokuphuma kwe-arc ye-cathodic eqhelekileyo, iijometri ezintsonkothileyo zinokubangela imiphumo yomthunzi kunye nokugqunywa kombala okungalinganiyo. Ukukhethwa kwezixhobo ke ngoko kufuneka kuqwalaselwe ulungiselelo kunye nenani lee-cathodes, ukujikeleza kwe-substrate kunye neendlela zokujikeleza, uyilo lwezixhobo, umgama ukusuka kumthombo ukuya kwi-substrate, kunye nokusasazwa kwe-plasma.
Inkqubo yokulawula i-substrate ene-axis ezininzi ecwangciswe kakuhle inokutshintsha rhoqo indlela esebenza ngayo xa ithelekiswa nomthombo we-coating, iphucula ukugquma kwe-coating kunye nokufana kobukhulu kwiindawo ezintsonkothileyo. Kwizinto zonyango ezixabisa kakhulu, uyilo lwe-fixture lubaluleke kakhulu kuba kufuneka luphucule ukusebenza kakuhle komthwalo ngelixa luqinisekisa unxibelelwano oluzinzileyo lombane, ukuvezwa kwe-plasma okusebenzayo, kunye nokubekwa okuphindaphindiweyo ukusuka kwibhetshi ukuya kwenye.
Unyango lwangaphambi konyango kunye nobunjineli boMdibaniso zibalulekile ekunamathelweni kokugquma
Kwimigqumo yezonyango esebenzayo, ukufumana iipropati zefilimu ezifunekayo kuqala ngokufumana umphezulu we-substrate ococekileyo nosebenzayo.
Ngaphambi kokufaka i-vacuum plasma kunye ne-ion etching zingasetyenziselwa ukususa ungcoliseko lomphezulu kunye neengqimba zomda obuthathaka ngelixa kusebenze umphezulu we-substrate. Ngokuxhomekeke kwizinto ze-substrate kunye nenkqubo yokugquma, umaleko ofanelekileyo wokubopha okanye isakhiwo se-interface esilinganisiweyo sinokufakwa ukuphucula ukunamathelana kwe-interfacial kunye nokunciphisa uxinzelelo olushiyekileyo.
Oku kubaluleke kakhulu kwizixhobo zonyango ezithwalwa ngokuphindaphindiweyo ngoomatshini, ukungqubana, ukubulala iintsholongwane, okanye iindawo ezirhabaxa. Ukwaleka okuneempawu ezintle zangaphakathi kusenokungaphumeleli ngaphambi kwexesha ukuba ukulungiswa komphezulu we-substrate kunye nojongano lwe-coating-substrate akulawulwanga ngokufanelekileyo.
Ngoko ke, iqonga lezixhobo zokugquma ezisebenzayo kwezonyango kufuneka libonelele ngeemeko zenkqubo ezizinzileyo nezilawulekayo zokucocwa kweplasma, ukubandlulula i-substrate, ulawulo lwegesi olusabelayo, kunye nokugquma i-coating, endaweni yokugxila kuphela kumthombo wokugquma.
Uqwalaselo lwezixhobo kufuneka luhambelane nenkqubo yokugquma
Iinkqubo ezahlukeneyo zokugquma ezisebenzayo zifuna ulungelelwaniso lwezixhobo ezahlukeneyo. Kwizinto zokugquma zePVD eziqinileyo, inkqubo ngokubanzi kufuneka inike amandla okuphuma kwe-cathodic arc evaporation okanye i-magnetron sputtering, ulawulo oluchanekileyo lwegesi olusabelayo, ulawulo lwe-substrate bias, kunye nentshukumo ethembekileyo ye-substrate.
Kwi-DLC kunye nezinye izinto zokugquma ezisebenzayo eziphambili, izixhobo zinokufuna ukudibanisa i-PECVD, i-PVD, okanye ubuchwepheshe bokugquma obuhlanganisiweyo, kuxhomekeke kwisakhiwo sefilimu esifunekayo kunye nokusebenza kwayo. Iiparameter ezinje ngoxinano lweplasma, ukuhamba kwegesi kwangaphambili, i-bias voltage, ubushushu bokugquma, kunye nobukhulu befilimu kufuneka zilawulwe ngokuchanekileyo ukuze kufunyanwe iimpawu zokugquma ezifunekayo.
Kwizinto zonyango ezibuthathaka kubushushu, ulawulo lobushushu be-substrate lolunye uqwalaselo olubalulekileyo. Umthwalo ogqithisileyo wobushushu unokubangela utshintsho kubukhulu, ukonakala kwe-substrate, okanye ukonakala kweempawu zezinto. Ke ngoko izixhobo kufuneka zibandakanye inkqubo yokupholisa efanelekileyo, icebo lolawulo lobushushu, kunye nokukwazi ukujonga inkqubo ukugcina umsebenzi ngaphakathi kwefestile yawo yobushushu evumelekileyo.
Ukungaguquguquki Kwemveliso Yimfuneko Ephambili Kwizicelo Zezonyango
Ukufakwa kwezixhobo zonyango akupheleli nje ekufumaneni ukufakelwa kwesampulu efanelekileyo kwisampulu enye. Kwimveliso yemizi-mveliso, umngeni obaluleke ngakumbi kukugcina umgangatho wokufakwa kwesampulu ophindaphindwayo kwiibhetshi ezahlukeneyo kunye nemijikelo yemveliso.
Uzinzo lwezixhobo, ukusebenza kwenkqubo ye-vacuum, uzinzo lweplasma, ulawulo lokuhamba kwegesi, ukuphinda-phinda kokunikezelwa kwamandla, intshukumo ye-substrate, ulawulo lobushushu, kunye nolawulo lweresiphi zonke ezi zinto zinokuchaphazela ukuhambelana kokugquma. Inkqubo eyilwe kakuhle ke ngoko kufuneka ibonelele ngolawulo lwenkqubo oluzinzileyo kunye neemeko zokubeka eziphindaphindwayo ngelixa inciphisa umahluko oxhomekeke kumqhubi.
Kwabavelisi bezixhobo zonyango, iindlela zokupheka zokugquma kufuneka ziphuhliswe kwaye ziqinisekiswe ngokwejometri yecandelo kunye neemfuno zesicelo. Iiparamitha eziphambili zenkqubo kufuneka zijongwe kwaye zirekhodwe kuyo yonke imveliso, zibonelele ngesiseko esithembekileyo sokulandelelwa kwenkqubo kunye nolawulo lomgangatho.
Ukusuka “kwiZixhobo zokuGcoba” ukuya kwiSisombululo sokuGcoba esiSebenzayo
Ukukhethwa kwezixhobo zokugquma izixhobo zonyango kufuneka ekugqibeleni kusekelwe kwikhonkco lenkqubo epheleleyo endaweni yeteknoloji yokugquma enye. Ukusuka kunyango lwangaphambi kwe-substrate kunye nokusebenza kwe-plasma ukuya kubunjineli be-interface, ukufakwa kwe-coating, ulawulo lobushushu, kunye nokuguqulwa kwe-substrate, inqanaba ngalinye linokuchaphazela ukusebenza kokugqibela kwe-coating.
Ngenxa yesi sizathu, icebo elisebenzayo lokufanisa izixhobo kufuneka liqale ngezinto ezisetyenziswa kwi-substrate, i-component geometry, inkqubo yokugquma ekujoliswe kuyo, iipropati zokusebenza ezifunekayo, ubushushu benkqubo obuvumelekileyo, amandla emveliso, kunye neemfuno zomgangatho. Ngokusekelwe kwezi parameters, iteknoloji yokufaka, uqwalaselo lwegumbi, ulungiselelo lwe-cathode okanye ithagethi, i-substrate fixture, inkqubo yokuhamba, inkqubo ye-vacuum, umbane, inkqubo yokulawula igesi, kunye noyilo lolawulo lwenkqubo lunokulungiswa ngokufanelekileyo.
I-Zhenhua Vacuum ibonelela nge-PVD, i-magnetron sputtering, i-cathodic arc ion plating, i-PECVD, kunye nezinye izixhobo zokugquma nge-vacuum kunye nezisombululo zenkqubo zokusetyenziswa konyango lomphezulu olusebenzayo.
