1. Kukanda kugadzirira
Kuti ugotungamira iyo inotevera Electrochemical bvunzo, 30mm inosarudzwa Polish uye bvisa iyo yakasara oxide layer leyer layer emafuro ne subaken ine acetPer Iyo inopfeka marara pamusoro peiyo simbi substrate ine doro uye mvura yakadzikira, uye maaipisa nemuridzi. Ipapo, Alumina (Al2o3), Grapheye uye Hybrid Carbon Nanotbe (MWNT-Cooohsdbs) yakagadzirirwa muCharportic (100: 0.2: 09.8: 0 :.2, 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2: 0.2 bhora banga (QM-3SS Kumhanya kwekutenderera kweiyo bhora chigayo kwaisirwa kusvika pa120 r / min, uye bhora chigayo chakatenderwa
Mushure mekunge bhora ragaya, isa kumhanya kwekutenderera kwebhora tangi kuve 1/2 neimwe nzira mushure mekunge bhora rekumira rapedzwa, uye isa iyo yekutenderera yebhora tank kuti ive 1/2 neimwe nzira mushure mekunge bhora rapedzwa. Bhora rakanyungudika ceramic Aggregate uye binder vakasanganiswa zvakanyanya maererano nehuwandu hwemari ye1.0: 0.8. Pakupedzisira, chinonamatira cramic cooting yakawanikwa nekuporesa maitiro.
2. Kuongorora kweCorrosion
Muchidzidzo ichi, iyo Electrochemical Corrosion Test At Eastts Shanghai Chenhua Chieltrocemical Workstation, uye bvunzo inotora matatu electrode bvunzo system. Iyo platinum Electrode ndiyo yebetsero yeElectrode, sirivha sirivha Batanidza rondedzero yeElectrode, yakashanda elekitori uye elecroliary elecrode muchiridzwa chekare nechiridzwa, sezvakaratidzwa muhuwandu 1 ne2
3. Tafel kuongorora kweElectrochemical Corrosion yejasi
Fig. 3 inoratidza iyo Tafel curve yeisina kugadziriswa uye ceramic coating yakabatanidzwa neakasiyana nano anowedzera mushure meElectrochemical Corrosion yeActrochemical Corrosion yeMagetsi Corrosion yeActrochemal. Iyo Corrostion Voltage, Corrosion Yazvino Density uye Magetsi Akasarudzika Test data yakawanikwa kubva kune electrochemal Corrosion bvunzo inoratidzwa muTafura 1.

Kana iyo Corrostion yazvino kuwanda uye iyo Corrosion kuramba kushanda kwakakwirira, iyo Corrosion inopesana nemhedzisiro yekubatira iri nani. Inogona kuoneka kubva kune nhamba 3 uye tafura 1 iyo nguva iyo nguva yekushora iri 19h, iyo Yakanyanya Corrosion Volsage / cm2 Zvinoratidza kuti kuunganidzira kwekukoshesa kunoshanda zviri nani basa uye kunogona kuvandudza kupesana nekukonzeresa kuungana mune zvisina kurongeka magetsi Electrolyte.
Kana 0.2% MWNT-Cooh-SDBS kana 0.2% Graphene yakaderera, kupokana kwekutora kwaiwedzera, uye kupokana nekubatirana kwakawedzera kuvandudzwa, ne pe 38.48% uye 40.10% zvakateerana. Kana iyo nzvimbo yakachinjika ne2.2% MWNT-cooh-sdbs uye 0.200 Grapheed yakaderedzwa kubva ku2,890 × 10-6 A / CM2 Ukoshi, hwakawedzera kubva pagumi nembiri nemakumi maviri nenomwe Zvinoratidza kuti chigadzirwa chakarongeka chine chekuita nehurongwa hwakanaka, uye maitiro emukodhi weCarbon Nanotubes neGriphene anokwanisa kubatsira zvakanyanya kukanganisa kweCoramic Coating.
4. Mhedzisiro yenguva yekunyudza pakubata zvisina kukodzera
Kuti uwedzere kuongororwazve kupokana kwekubatisa, achifunga nezve pesvedzero yenguva yemuenzaniso muyedzo yekudzikama, iyo yekudzvinyirira yejasi ina panguva dzakasiyana kunyudzwa. Sezvakaratidzwa mumufananidzo 4.

Pazororo rekutanga kunyudzwa (10 h), nekuda kwekunaka kwehuremu uye chimiro chekuchema, iyo electrolyte yakaoma kunyudza mukucheka. Panguva ino, kuunganidza kweCeramic kunoratidza kuramba kwakanyanya. Mushure mekusvika kwenguva yakati rebei, kupokana kunoderedza zvakanyanya, nekuti nekufamba kwenguva, iyo Electrolyte zvishoma nezvishoma nzira kuburikidza neCoating uye inopinda mumativi, zvichikonzera kuderera kwakakura mukupokana kwe kuungana.
Muchikamu chechipiri, apo zvigadzirwa zvecorosion zvichikwira kune imwe mari, iyo yakasarudzika yakavharwa uye iyo gap inovharirwa zvishoma nezvishoma. Panguva imwecheteyo, apo maElectrolyte vakapinda mumhirizhonga yekubatira kupinzwa kweiyo Electrolyte mumatrix uye inowedzera kukosha kwekupokana. Kana iyo isina bara masimbi matrix yaro yemagetsi yakarongedzwa, mazhinji egirini flucculent precipitation inogadzirwa pasi peiyo Electrolyte. Solution yeElectrolytic haina kuchinja ruvara kana maElectrlyzing sampuli yemuenzaniso, iyo inogona kuratidza kuvepo kwezvinhu zviri pamusoro pemakemikari.
Nekuda kwenguva pfupi yekukwenenzvera uye yakakura yekuchengetedza zvinhu, kuitira kuti uwedzere kuwana hukama hwakakodzera hwehukama hweElectrochemical parameter, tafel curves ye19 h uye 19,1,5 h vanoongororwa. Iyo Corrostion Yazvino Kureba uye Kugadziriswa Yakawanikwa neAnimpwin Ongorora Software inoratidzwa muTafura ye19 H, ichienzaniswa neyakagadziriswa yeAlumina uye Alumina Composite Coating NO zvidiki uye kukosha kwekupokana kwakakura. Iko kukosha kwekudzivisa kwekuverenga carmic kune kabhoni Nanotubes uye kuchema kwekomboni uye nepo maitiro echiGiredis ane mapoinzi ehondo imwe chete uye maviri-maviri-dimensional grapeni. inovandudza kurwisa kwecorosion yezvinyorwa.
Nekuwedzera kwekunyudzwa nguva (19.5 h), kupokana kwekuwedzera kwechidimbu, zvichiratidza kuti iri muchikamu chechipiri cheCorrosion uye simbi oxide firimu rinogadzirwa pamusoro peiyo substrate. Saizvozvowo, nekuwedzera kwenguva, kupokana kweiyo Alumina Ceramic inowedzerawo, zvichiratidza kuti panguva ino, maElectrolyte akapinda mubatanidzwa wekubatanidza / matrix, matrix, uye akagadzira oxide firimu kuburikidza nemakemikari maitiro.
Kuenzaniswa neAlumina Coating ane 0.2% MWNT-cooh-Sdbs na22.94%, 25.60% uye 9.61% zvakateerana, zvichiratidza kuti maElectrolyte haana kupinda mukati Mubatanidzwa pakati pekuvhara uye substrate panguva ino, izvi imhaka yeCarbon Nanotubes neGriphene inovhara kupinda kweiyo Electrolyte, nokudaro ichidzivirira matrix. Mhedzisiro yeiyo yeiyo mbiri inoenderera mberi yakasimbiswa. Iyo cooting ine maviri maNA zvemidziyo ine zvirinani kukanganisa kupesana.
Kuburikidza neTafel curve uye shanduko yemagetsi asina kukodzera kukosha kuramba kwekunamatira cramic coating. Kuti uenderere mberi nekutsvaga mhedzisiro yeNano inowedzera pakubata kweiyo coating, iyo micro sorphology yekuvhara mushure mekutora kwaColatros yakacherechedzwa.
