Indlela iPVD Esebenza Ngayo: Ukutyhila Iimfihlo Zale Ntekhnoloji Iphambili
Intsimi yophuhliso lwetekhnoloji ihlala itshintsha, inika izisombululo ezintsha kumashishini ahlukeneyo. Enye yezi nkqubela phambili yiteknoloji yePVD (Physical Vapor Deposition), ezisa umlinganiselo omtsha kubunjineli bomphezulu. Kule posi yebhlog, siza kujonga nzulu indlela esebenza ngayo iPVD kwaye sihlole indlela le teknoloji imangalisayo eguqula ngayo iinkalo ezahlukeneyo.
I-PVD, njengoko igama lisitsho, ibandakanya ukubeka iifilimu ezincinci kwiindawo eziqinileyo ngenkqubo ebonakalayo. Le teknoloji isebenzisa imigaqo eyahlukileyo ukuphucula ukuqina, ukusebenza kunye nobuhle beemveliso ezahlukeneyo. Ngoko ke, makhe sijonge nzulu indlela esebenza ngayo i-PVD size siqonde ukuba ithetha ukuthini.
Eyona nto iphambili kwi-PVD kukudala indawo yokucoca umoya ngaphakathi kwigumbi eliyilwe ngokukodwa. Eli qhekeza lokucoca umoya liqinisekisa ukususwa kwazo naziphi na izinto ezingcolisayo, nto leyo ebonelela ngendawo efanelekileyo yenkqubo yokugquma. Nje ukuba igumbi elitywiniweyo livalwe, izinto ezijoliswe kuzo (ezinokuba yintsimbi, i-alloy, i-ceramic okanye i-polymer) zitshiswa kakhulu. Ngenxa yoko, ii-athomu okanye iimolekyuli kwizinto ezijoliswe kuzo ziguquka zibe yimeko yegesi.
Ngoku kuza inxalenye ephambili yendlela esebenza ngayo i-PVD – ukubeka ezi atomu zegesi okanye iimolekyuli kumphezulu wento efunekayo. Ukuze kufezekiswe oku, kufuneka umthombo wamandla ophezulu njenge-arc okanye i-plasma. Lo mthombo wamandla uhlasela iiathomu, ubangele ukuba ziqhekeke kwaye zenze ilifu le-plasma. Ilifu le-plasma emva koko lityhala iiathomu kumphezulu, apho iiathomu zihlangana khona kwaye zenze ifilimu encinci.
Inkqubo ye-PVD ineenzuzo ezininzi kuneendlela zokugquma zemveli. Okokuqala, ivumela ulawulo oluchanekileyo lobukhulu kunye nokwakheka kwefilimu egciniweyo. Abavelisi banokufikelela kwiingubo ezifanayo kakhulu, nokuba zikwiimo ezinzima kunye neenkcukacha ezintsonkothileyo. Okwesibini, ifilimu ye-PVD inamathele kakuhle kwi-substrate, iqinisekisa ukuhlala ixesha elide kunye nokumelana nokuguguleka. Ukongeza, itekhnoloji ye-PVD ivumela ukufakwa kweengubo ezineempawu ezikhethekileyo ezifana nobunzima obuphezulu, ukungqubana okuphantsi kunye nokumelana nokugqwala okugqwesileyo.
Ukusetyenziswa kwe-PVD kubanzi kakhulu kwaye kubandakanya amashishini ahlukeneyo. Ukususela kwiindawo zeemoto kunye nezixhobo zokusika ukuya ekugqityweni kokuhombisa kunye nezixhobo zonyango, obu buchwephesha butshintsha indlela esisebenzisana ngayo neemveliso zemihla ngemihla. Umzekelo, ii-PVD coating kwizixhobo zokusika zinokwandisa kakhulu ubomi bazo benkonzo, zinciphise isidingo sokutshintshwa rhoqo. Ngokufanayo, ii-PVD coating kwizixhobo zeemoto zonyusa ukuqina kwazo kunye nokusebenza kwazo kakuhle, zinceda ukuphucula ukonga amafutha kunye nokunciphisa ukukhutshwa komoya.
Kutshanje kuye kwatyhilwa ukuba izazinzulu bezihlola amandla e-PVD asebenza ngayo kumandla avuselelekayo. Ngokusebenzisa ii-PVD coatings kwiiphaneli zelanga, abaphandi bajonge ukwandisa ukusebenza kwazo kunye nobomi bazo bonke. Ngokufanayo, ii-PVD coatings kwiiblades ze-wind turbine zinokunyusa ukumelana kwazo nokukhukuliseka, ngaloo ndlela zandise imveliso yamandla.
Umgaqo wendlela esebenza ngayo i-PVD yindlela entsha emangalisayo eye yaguqula ubunjineli bomphezulu. Ngokulawula ngokuchanekileyo nokufaka iifilimu ezincinci, ii-PVD coatings ziphucula ukuqina, ukusebenza kunye nobuhle beemveliso ezahlukeneyo. Ngezicelo zayo ezahlukeneyo kumashishini, obu buchwepheshe butsha buyaqhubeka nokuvula indlela yophuhliso oluthe kratya. Hlala ubukele njengoko sityhila izinto ezinomdla ngakumbi kwicandelo le-PVD.
