Indlela yokusetyenziswa
1. Ukulungiswa kwepeyinti: Emva kokuvuselela okanye ukugubha kakuhle, inokusetyenziswa emva kokuhluzwa ngesikrini se-300-mesh filter. Ukucocwa kwezinto ezisisiseko: Emva kokuthoba kunye nokususa igrisi, kuyacetyiswa ukuba wenze i-sandblasting ukunyusa umgangatho womhlaba. Isiphumo esihle kakhulu se-sandblasting sifezekiswa nge-46-mesh corundum (i-corundum emhlophe), kwaye kufuneka ifike kwi-Sa2.5 grade okanye ngaphezulu. Izixhobo zokugquma: Sebenzisa izixhobo zokugquma ezicocekileyo nezomileyo ukuze uqiniseke ukuba akukho manzi okanye ezinye izinto ezingcolileyo ezibambelela kuzo, ukuze zingachaphazeli isiphumo sokugquma okanye zibangele iimveliso ezineziphene.
2. Indlela yokwaleka: Ukutshiza: Tshaza kwiqondo lobushushu begumbi. Kunconywa ukulawula ubukhulu bokutshiza ngaphakathi kwe-50 ukuya kwi-100 microns. Ngaphambi kokutshiza, i-workpiece emva kwe-sandblasting kufuneka ihlambuluke nge-ethanol ye-anhydrous kwaye yomiswe ngomoya oxinyiweyo. Ukuba ukuncipha okanye ukucutheka kuyenzeka, i-workpiece inokufudunyezwa ukuya kutsho malunga ne-40℃ phambi kokutshiza.
3. Izixhobo zokugquma: Sebenzisa umpu wokutshiza ngobubanzi be-1.0. Umpu wokutshiza we-diameter encinci unesiphumo esingcono se-atomization kunye nesiphumo esifanelekileyo sokutshiza. Icompressor yomoya kunye nesihluzo somoya kufuneka sixhotyiswe.
4. Ukunyangwa kwe-Coating: Emva kokugqitywa kokutshiza, vumela i-workpiece ngokwemvelo yome malunga nemizuzu engama-30, uze uyibeke kwi-oven kwaye uyigcine kwi-280 degrees imizuzu engama-30. Emva kokupholisa, inokukhutshwa ukuze isetyenziswe.
Yahlukile kuYoucai
1. Ukuzinza kobugcisa
Emva kovavanyo olungqongqo, inkqubo yetekhnoloji ye-aerospace-grade nanocomposite ceramic ihlala izinzile phantsi kweemeko ezinzima, ukumelana nokushisa okuphezulu, ukutshitshiswa kwe-thermal kunye nokubola kweekhemikhali.
2. Iteknoloji ye-Nano-dispersion
Inkqubo yokusabalalisa ekhethekileyo iqinisekisa ukuba i-nanoparticles ihanjiswe ngokulinganayo kwi-coating, igweme i-agglomeration. Ukuphathwa kwe-interface esebenzayo kwandisa ukudibanisa phakathi kweengqungquthela, ukuphucula amandla okudibanisa phakathi kwengubo kunye ne-substrate kunye nokusebenza ngokubanzi.
3. Ukulawulwa kokwambathisa
Ukuqulunqwa okuchanekileyo kunye nobuchule obudibeneyo buvumela ukuba ukusebenza kwe-coating kulungiswe, njengokuqina, ukuxhatshazwa kokugqoka kunye nokuzinza kwe-thermal, ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
4. Iimpawu zesakhiwo seMicro-nano:
Amasuntswana e-nanocomposite ceramic asonga amasuntswana e-micrometer, agcwalise izithuba, enze i-coating eshinyeneyo, kwaye aphucule ukubumbana kunye nokuxhathisa umhlwa. Okwangoku, i-nanoparticles ingena kumphezulu we-substrate, yenza i-metal-ceramic interphase, eyandisa amandla okubambisana kunye namandla onke.
Umgaqo wophando nophuhliso
1. Umba wokuhambelana nokwandiswa kwe-thermal: Ii-coefficients zokwandiswa kwe-thermal zetsimbi kunye nezinto ze-ceramic zihlala zihluka ngexesha lokufudumala kunye neenkqubo zokupholisa. Oku kunokukhokelela ekubunjweni kwe-microcracks kwi-coating ngexesha lenkqubo yokukhwela ibhayisikile, okanye ukukhupha. Ukujongana nalo mbandela, i-Youcai iphuhlise izinto ezintsha zokugubungela i-coefficient yokwandiswa kwe-thermal isondele kwi-substrate yensimbi, ngaloo ndlela inciphisa uxinzelelo lwe-thermal.
2. Ukumelana nokutshatyalaliswa kwe-thermal kunye ne-thermal vibration: Xa i-metal surface coating itshintsha ngokukhawuleza phakathi kwamaqondo aphezulu kunye namaqondo aphantsi, kufuneka ikwazi ukumelana noxinzelelo olubangelwa yi-thermal ngaphandle komonakalo. Oku kufuna ukuba i-coating ibe nokuxhathisa ukothuka kwe-thermal. Ngokulungisa i-microstructure ye-coating, njengokwandisa inani le-interfaces yesigaba kunye nokunciphisa ubungakanani beenkozo, i-Youcai inokunyusa ukuxhathisa ukothuka kwe-thermal.
3. Amandla okudibanisa: Amandla okudibanisa phakathi kwengubo kunye ne-metal substrate ibalulekile ekuzinzeni kwexesha elide kunye nokuqina kwengubo. Ukwandisa amandla okudibanisa, u-Youcai wazisa umaleko ophakathi okanye umaleko wenguqu phakathi kwengubo kunye ne-substrate ukuphucula ukumanzi kunye nokudibanisa kweekhemikhali phakathi kwezi zibini.
