unyango ubushushu umphezulu imichiza
Unyango lobushushu beMichiza yinkqubo yonyango lobushushu apho i-workpiece ibekwe kwindawo ethile yokufudumeza kunye nokugcinwa kobushushu, ukuze iiathom ezisebenzayo eziphakathi zingene kumaleko womphezulu we-workpiece, ngaloo ndlela itshintsha ukwakheka kweekhemikhali kunye nokwakheka kwe umaleko womphezulu we-workpiece, kwaye emva koko utshintshe ukusebenza kwayo. Unyango lobushushu bemichiza lukwayenye yeendlela zokufumana ubunzima bomphezulu, lukhuni kunye nelinen. Xa kuthelekiswa nokucinywa komphezulu, unyango lobushushu beekhemikhali alutshintshi nje kuphela ubume bomphezulu bentsimbi, kodwa luphinde lutshintshe ukwakheka kweekhemikhali. Ngokwezinto ezahlukeneyo ezingeniswayo, unyango lobushushu beekhemikhali lunokwahlulwa lube yi-carburizing, i-nitriding, i-multi-infiltration, i-infiltration yezinye izinto, njl.
Unyango lobushushu obusetyenziswa rhoqo ngemichiza:
I-Carburizing, i-nitriding (eyaziwa ngokuba yi-nitriding), i-carbonitriding (eyaziwa ngokuba yi-cyanidation kunye ne-nitriding ethambileyo), njl njl.
ukutyabeka ngentsimbi
Ukugquma enye okanye ngaphezulu kweengubo zetsimbi kumphezulu wesiseko kunokuphucula kakhulu ukuxhathisa kwayo, ukuxhathisa ukubola kunye nokumelana nobushushu, okanye ukufumana ezinye iipropati ezikhethekileyo. Kukho i-electroplating, i-chemical plating, i-composite plating, i-infiltration plating, i-hot dip plating, i-vacuum evaporation, i-spray plating, i-ion plating, i-sputtering kunye nezinye iindlela.
I-Metal Carbide Coating - i-Vapor Deposition
Itekhnoloji yokubeka umphunga ibhekisa kuhlobo olutsha lobugcisa bokugquma obufaka izinto zesigaba somphunga eziqulethe izinto zokubeka kumphezulu wemathiriyeli ngeendlela eziphathekayo okanye zekhemikhali ukwenza iifilimu ezibhityileyo.
Ngokomgaqo wenkqubo yokubeka, itekhnoloji yokubeka umphunga inokohlulwa ibe ngamacandelo amabini: ukubekwa komphunga obonakalayo (PVD) kunye nekhemikhali yokubeka umphunga (CVD).
Ukubekwa Komphunga Wasemzimbeni (PVD)
Ukubekwa komphunga wokoqobo kubhekiselele kwitekhnoloji apho i-material ifakwa umphunga ibe yi-athomu, iimolekyuli okanye i-ionized ibe yi-ion ngeendlela eziphathekayo phantsi kweemeko zokufunxa, kwaye ifilimu ebhityileyo ifakwe kumphezulu wezinto ngokusebenzisa inkqubo yesigaba segesi.
Itekhnoloji yokubekwa ngokwasemzimbeni ikakhulu ibandakanya iindlela ezintathu ezisisiseko: ukukhutshwa kwevacuum, ukutshiza, kunye ne-ion plating.
Ukubekwa komphunga womzimba kunoluhlu olubanzi lwezinto ezisebenzayo ze-substrate kunye nezixhobo zefilimu; inkqubo ilula, igcina izinto eziphathekayo, kwaye ayinangcoliso; ifilimu efunyenweyo ineenzuzo zokubambelela ngokuqinileyo kwisiseko sefilimu, ubukhulu befilimu efanayo, ukudibanisa, kunye neepinhole ezimbalwa.
Ukubekwa kweMichiza yoMphunga (CVD)
Ukubekwa komphunga wekhemikhali kubhekisa kwindlela apho irhasi exutyiweyo idibana nomphezulu wesubstrate kwiqondo lobushushu elithile ukuze yenze isinyithi okanye ifilimu ebumbayo kumphezulu wesubstrate.
Ngenxa yokuba ifilimu yokubeka umphunga wekhemikhali inokumelana nokunxiba kakuhle, ukuxhathisa ukugqwala, ukumelana nobushushu kunye nombane, i-optical kunye nezinye iipropathi ezikhethekileyo, isetyenziswe ngokubanzi kwimveliso yoomatshini, i-aerospace, uthutho, ishishini lemichiza yamalahle kunye namanye amacandelo oshishino.
