Feem ntau siv cov ntaub ntawv cladding muaj xws li tawv ceramics thiab nickel-based self-fusing alloys. Cov kev tshawb fawb tau pom tias qhov hardness thiab hnav tsis kam ntawm txheej tom qab laser melting ntawm SiC yog qhov zoo dua.
3. Micro-arc oxidation tshuab
Micro-arc oxidation tuaj yeem tsim ib txheej ntawm cov yeeb yaj kiab dense thiab corrosion txhim kho ntawm titanium alloy los ntawm kev sib txuas nrog lwm cov kev hloov kho sab nrauv. Micro-arc oxidation technology nyob rau hauv titanium alloy nto npaj ntawm ceramic txheej, nrog tsawg npaj kub, yooj yim cov cuab yeej, tshuaj tiv thaiv ib puag ncig, zaj duab xis txheej uniformity thiab ceev thiab lwm yam zoo. Los ntawm micro-arc oxidation thev naus laus zis, txheej txheej zaj duab xis nrog siab hardness thiab siab zaj duab xis puag lub zog tuaj yeem tsim rau saum npoo ntawm titanium alloy, uas txhim kho qhov hnav tsis kam thiab corrosion kuj.
4. Multi-theem, multi-theem, multi-scale mix reinforcement tsim
Kev tshoov siab los ntawm qhov ua tau zoo ntawm cov khoom siv roj ntsha zoo, lub tswv yim tsim ntawm ntau theem, ntau theem, ntau qhov sib xyaw ua ke tuaj yeem tsim nrog cov tawv tawv, siab tawv thiab zoo hnav tsis kam ntawm txheej.
5.Thermal Spraying Technology
Thermal spraying thev naus laus zis los ntawm cua sov cov khoom siv tshuaj tsuag mus rau lub xeev ntws thiab ua kom nrawm nrawm rau ntawm qhov chaw ntawm substrate, tsim cov txheej txheej nrog cov haujlwm tshwj xeeb. Cov tshuab no tuaj yeem txhim kho qhov hnav tsis kam ntawm titanium alloys. Cov khoom siv tshuaj tsuag feem ntau suav nrog nickel-coated graphite, monolithic hlau thiab cov ntaub ntawv alloy.
6. Txias txau tshuab
Txias tshuab tshuab yog ib txoj hauv kev siv cov roj cua kub ceev kom ceev cov khoom siv hmoov mus rau qhov kub ceev thiab ua kom nws deform plastically thaum nws tsoo lub substrate rau saum npoo los tsim cov txheej. Cov cuab yeej siv no tuaj yeem siv los npaj cov txheej txheem hnav-tiv taus rau saum npoo ntawm titanium alloys, uas muaj qhov zoo ntawm cov txheej txheem muaj zog thiab cov porosity tsawg.
7. Ion implantation technology
Ion implantation thev naus laus zis hauv lub tshuab nqus tsev, qhov kub thiab txias, siab zog ions rau hauv cov hlau ze ntawm txheej txheej, tsim cov txheej txheem tshiab ntawm cov txheej txheem hlau, tsim cov txheej txheej hlau thiab cov txheej txheem nrog lub zog sib txuas, nrog zoo hnav-resistant nyhuv.
8. Vapor Phase Deposition Technology
Vapor theem deposition tuaj yeem tsim ib txheej txheej txheej txheej ntawm titanium alloy, los ntawm kev kho qhov muaj pes tsawg leeg thiab cov qauv ntawm txheej, nws tuaj yeem txhim kho cov khoom hnav-tiv taus ntawm titanium alloy.
9.Self-lubricating composite txheej
Cov kws tshawb fawb tseem tau npaj cov txheej txheem ntawm tus kheej lubricating composite coatings nyob rau saum npoo ntawm titanium alloys, uas muaj cov theem zog ntxiv thiab lubricating theem, xws li TiN, TiMo, Ti-Ni, thiab MoS2, TiS, cov txheej txheem no tuaj yeem muab cov khoom siv rau nws tus kheej lubricating thaum txhim kho. hnav tsis kam.
10. High entropy alloy siab kub txheej txheej
High-entropy alloy high-temperature coatings muaj ntau yam khoom zoo heev, uas tuaj yeem ua kom zoo ntxiv los ntawm kev kho cov ntsiab lus ntawm ib lossis ntau dua ntawm cov ntsiab lus no, thiab yog li ntawd muaj cov ntawv cog lus zoo heev. Txawm li cas los xij, cov txheej txheem no tseem nyob rau hauv kev tshawb fawb theem, yuav tsum tau daws cov ntsiab lus piv tsis tsim nyog thiab cov ntsiab lus matrix ntawm cov yaj cladding txheej ntawm cov tshuaj tiv thaiv thiab lwm yam teeb meem.
