Ngaba ukusetyenziswa kwe-CVD silicon carbide coating ingaphucula ngokufanelekileyo ubomi bokusebenza bamacandelo?

I-CVD silicon carbide coating yitekhnoloji eyenza ifilimu ebhityileyo kumphezulu wamacandelo, enokwenza ukuba amacandelo abe nokumelana nokunxiba, ukumelana nokugqwala, ukumelana nobushushu obuphezulu kunye nezinye iipropathi. Ezi zakhiwo zibalaseleyo zenza i-CVD silicon carbide coatings isetyenziswe ngokubanzi kwiindawo ezininzi, ezifana nobunjineli bomatshini, i-aerospace, izixhobo zombane, njl.I-CVD ye-silicon carbide yokugqumaukuphucula ubomi bokusebenza bamacandelo? Eli nqaku liza kuhlolisisa lo mbandela.

Okokuqala, ubulukhuni beI-CVD ye-silicon carbide yokugqumaiphezulu kakhulu, idla ngokufikelela kuma-2000 ukuya kuma-3000HV. Oku kuthetha ukuba indawo yokwaleka inokumelana okuqinileyo nemikrwelo kunye nokunxiba, kwaye inokukhusela ngokufanelekileyo indawo yobuso kwimikrwelo yomatshini kunye nokunxiba. Umzekelo, kwinkalo yobunjineli boomatshini,I-CVD ye-silicon carbide yokugqumakumphezulu wezixhobo zokusika kunokwandisa kakhulu ubomi babo benkonzo kunye nokuphucula ukusebenza kakuhle. Ngokufanayo, kwintsimi yezixhobo zombane, unyango lwe-CVD silicon carbide coating phezu kwezinto ezinjengama-contacts anokunciphisa ngokufanelekileyo ukunxiba kwabafowunelwa kunye nokwandisa ubomi babo.

Okwesibini,I-CVD ye-silicon carbide yokugqumainokumelana nokuhlwa okungcono. Xa kuthelekiswa nezinto ezininzi zetsimbi, isilicon inokumelana nokugqwala okungcono, kunye ne-CVD silicon carbide coating iphucula ngakumbi ukuxhathisa ukubola kwamalungu. Kwezinye iindawo ezine-acidic kunye ne-alkaline, i-CVD silicon carbide coating inokukhusela indawo yecandelo kwi-corrosion kunye nokwandisa ubomi benkonzo yecandelo. Umzekelo, kumzi-mveliso weekhemikhali, i-CVD silicon carbide coating kumphezulu wevalve inokunyusa ukomelela kokubola kwevalve kwaye yandise ubomi bayo benkonzo.

Ukwengeza,Iingubo ze-silicon carbide zeCVDube nokuzinza okulungileyo kumaqondo obushushu aphezulu. I-silicon inendawo ephezulu yokunyibilika kunye nozinzo olungcono lobushushu obuphezulu, kwaye i-CVD silicon carbide coating iphakamisa ngakumbi ukuzinza kobushushu obuphezulu becandelo. Kwiindawo eziphezulu zokushisa, i-CVD silicon carbide coatings inokumelana ngokufanelekileyo ne-oxidation, i-delamination kunye nezinye iingxaki, ukukhusela amacandelo kwimiphumo yeendawo eziphezulu zokushisa. Ngokomzekelo, kwintsimi ye-aerospace, i-CVD silicon carbide coating kumphezulu weenjini ze-injini inokuphucula ukuxhathisa ubushushu obuphezulu bee-blades kunye nokwandisa ubomi benkonzo ye-injini.

Ukongeza, i-CVD silicon carbide coating nayo ineempawu ezilungileyo zokuqhuba i-thermal. I-Silicon inomgangatho ophezulu we-thermal conductivity, kunye ne-CVD silicon carbide coatings ngokubanzi ine-conductivity engcono ye-thermal. Oku kuvumela i-CVD silicon carbide coating ukuba ikhuphe ngokufanelekileyo ubushushu, ikhusele umonakalo wecandelo ngenxa yokushisa. Ngokomzekelo, kwintsimi yezixhobo ze-elektroniki, i-CVD silicon carbide coating phezu kwendawo yokutshisa ukushisa inokuphucula ukuhanjiswa kwe-thermal ye-heat sink kunye nokuthintela amacandelo ukuba angaphumeleli ngenxa yokushisa.

Isishwankathelo, ukusetyenziswa kwe-CVD silicon carbide coating kunokuphucula ngokufanelekileyo ubomi bokusebenza bamacandelo. Ubunzima bayo obuphezulu, ukuxhathisa okulungileyo kwe-corrosion, ukuzinza kobushushu obuphezulu kunye ne-thermal conductivity yenza ukuba umphezulu wecandelo uxhathise ngcono imikrwelo, ukunxiba, ukubola, ubushushu obuphezulu kunye nezinye iipropathi. Ngoko ke, kwiinkalo ezininzi, unyango lwe-CVD silicon carbide coating kumacandelo lunokwandisa ubomi benkonzo yamacandelo kunye nokuphucula ukuthembeka kwecandelo. Nangona kunjalo, kufuneka kuqatshelwe ukuba kwizicelo zangempela, izixhobo ezithile, ukuyila kunye nenkqubo yezinto kufuneka zidibaniswe ukuze kuphunyezwe iziphumo ezisebenzayo.
