Cov hau kev rau kev txhim kho Txheej Txheej adhesion ntawm Chrome Plating ntawm TC6 Titanium Qhov

Titanium thiab nws cov khoom siv alloys yog cov tshuaj tiv thaiv xim heev, nws' s yooj yim los tsim kom muaj cov yeeb yaj kiab oxide rau ntawm lawv qhov chaw, thiab nws nyuaj rau tau txais zoo lo nplaum rau hauv cov txheej txheem plating. Peeling thiab blister oflen curred tom qab chrome plating txheej txheem rau qee yam qauv dav hlau tsaws iav （TC6 titanium qhov chaw hich tau cuam tshuam tiag tiag kev xa khoom ntawm cov khoom. Los ntawm kev txheeb xyuas qhov cuam tshuam txog cov txheej txheej ntawm cov lo nplaum, ntau txoj kev siv feem ntau los txhim kho qhov kev hloov kho yog piav luv luv, thiab cov hau kev los txhawm rau txhawm rau txhawm rau sib dhos.

Titanium thiab titanium alloys muaj qhov ua tau zoo-rau-loj piv, kev ua haujlwm zoo corrosion, thiab kev ua tau zoo hauv nruab nrab kub. Lawv tau siv dav hauv ntau lub teb, tshwj xeeb tshaj yog kev lag luam aerospace. 2. Txawm li cas los xij, vim lawv txoj kev hnav tsis zoo tiv thaiv, cov nplaim yog qhov yooj yim rau kev khawb thiab nyiaj txhiv. , Kev ua haujlwm tsis zoo ntawm vuam thiab lwm yam luv luv txwv nws cov kev thov ntau yam. Hauv tsev thiab txawv teb chaws, cov txheej txheem electroplating feem ntau yog siv rau kev kho saum npoo ntawm titanium thiab titanium alloys txhawm rau txhim kho cov khoom nto ntawm titanium, muab nws lub cev lub cev tshiab, thiab nthuav cov kev siv ntawm H. Piv txwv li, chromium plating lossis electroless nickel. plating ntawm titanium thiab sis alloys tuaj yeem ua rau kom lub ntsej muag tawv thiab txhim kho hnav tsis kam; tooj liab lossis nyiaj plating tuaj yeem txhim kho thaj chaw ntawm cov ntu hauv cov kub-thauj cov kabmob, tiv thaiv cov kua nplaum txuas thiab micro-seismic xeb. Qhov no yog qhov tseem ceeb heev rau titanium qhov chaw sib txuas los ntawm kev siv tshuab, xws li compressor discs, blades, thiab lwm yam.; hauv kev lag luam aerospace, kub-plating titanium qhov chaw tuaj yeem txhim kho lawv qhov kev ua kom pom lub ntsej muag; tooj liab lossis npib tsib xee plating tuaj yeem hloov kho cov titanium Brazing kev ua tau zoo ntawm ntu 3. Titanium yog hlau nquag, tab sis feem ntau titanium thiab titanium alloys qhia cov khoom ruaj khov. Qhov no vim tias titanium muaj qhov sib txuam nrog cov pa oxygen thiab nitrogen hauv huab cua, thiab nws yooj yim rau Aib thiab tuab passivation zaj duab xis yog tsim rau saum npoo. Thaum titanium alloy electroplating, txhawm rau kom tau txais ib txheej nrog kev sib koom tes sib zog, zaj duab xis passivation nyob rau saum npoo yuav tsum tau muab tshem tawm tag nrho, tab sis qhov oxidation tus nqi ntawm titanium yog ceev, thiab zaj duab xis passivation tshem tawm Nws yuav tsim dua tshiab rau lub sijhawm, uas kuj tseem yog qhov laj thawj vim li cas titanium alloy muaj kev tiv thaiv zoo corrosion. Tib lub sijhawm, qhov zaj duab xis oxide no tseem ua rau nws tsis yooj yim rau electroplating ntawm titanium alloy. Yog tias electroplating nqa tawm raws li cov txheej txheem hauv cov pa, nws yuav tsis tuaj yeem tau txais qhov adhesion zoo. Kev Txheej Txheem. Vim li no, kev ua haujlwm no tsom rua kev sim ua lub ntsiab ntawm qee cov txheej txheem uas tau txais txiaj ntsig los txhim kho qhov kev sib txuas ntawm cov txheej txheem chromium txheej ntawm titanium alloy qhov chaw.
