4. Coating curing: Tom qab cov tshuaj tsuag tiav lawm, cia lub workpiece ib txwm nto qhuav li 30 feeb, ces muab tso rau hauv qhov cub thiab khaws cia ntawm 280 degrees rau 30 feeb. Tom qab txias, nws tuaj yeem muab tshem tawm los siv.
Unique rau Youcai
1. Kev ruaj ntseg
Tom qab kev sim nruj, cov txheej txheem aerospace-qib nanocomposite ceramic tseem nyob ruaj khov nyob rau hauv huab cua txias, tiv taus kub, thermal shock thiab tshuaj lom neeg corrosion.
2. Nano-dispersion technology
Cov txheej txheem dispersion tshwj xeeb ua kom ntseeg tau tias cov nanoparticles sib npaug sib npaug hauv cov txheej, tsis txhob agglomeration. Kev sib cuam tshuam zoo kev kho mob txhim kho kev sib raug zoo ntawm cov khoom, txhim kho kev sib raug zoo ntawm cov txheej thiab substrate nrog rau kev ua tau zoo tag nrho.
3. Txheej controllability
Cov txheej txheem meej thiab cov txheej txheem sib xyaw ua kom cov txheej txheem ua tau zoo tuaj yeem kho tau, xws li hardness, hnav tsis kam thiab thermal stability, ua tau raws li qhov yuav tsum tau ua ntawm kev siv sib txawv.

Nanocomposite tej hub qhwv qhwv micrometer sau, sau cov khoob, tsim cov txheej ntom ntom, thiab txhim kho compactness thiab corrosion tsis kam. Lub caij no, nanoparticles nkag mus rau saum npoo ntawm lub substrate, tsim cov hlau-ceramic interphase, uas txhim kho lub zog sib txuas thiab tag nrho lub zog.
Kev tshawb fawb thiab kev txhim kho txoj cai
1. Thermal expansion matching teeb meem: Lub thermal expansion coefficients ntawm hlau thiab ceramic cov ntaub ntawv feem ntau txawv thaum lub sij hawm cua sov thiab txias txheej txheem. Qhov no yuav ua rau tsim cov microcracks nyob rau hauv txheej thaum lub sij hawm kub cycling txheej txheem, los yog txawm tev tawm. Txhawm rau daws qhov teeb meem no, Youcai tau tsim cov ntaub ntawv txheej tshiab uas nws cov coefficient ntawm thermal expansion yog ze rau ntawm cov hlau substrate, yog li txo cov thermal stress.
2. Resistance rau thermal shock thiab thermal vibration: Thaum cov hlau nto txheej ceev hloov ntawm qhov kub thiab txias, nws yuav tsum muaj peev xwm tiv taus qhov tshwm sim thermal tsis muaj kev puas tsuaj. Qhov no yuav tsum tau lub txheej kom muaj thermal shock kuj zoo heev. Los ntawm optimizing lub microstructure ntawm txheej, xws li nce tus naj npawb ntawm theem interfaces thiab txo cov grain loj, Youcai tuaj yeem txhim kho nws cov thermal shock resistance.
3. Kev sib khi lub zog: Lub zog sib txuas ntawm cov txheej thiab cov hlau substrate yog qhov tseem ceeb rau kev ruaj ntseg ntev thiab durability ntawm txheej. Txhawm rau txhim kho lub zog ntawm kev sib raug zoo, Youcai qhia txog cov txheej txheem nruab nrab lossis cov txheej txheem hloov pauv ntawm cov txheej txheem thiab cov substrate los txhim kho cov wettability thiab tshuaj sib txuas ntawm ob.
