Titanium alloys tau dav siv nyob rau hauv Aerospace, kev lag luam vim lawv qhov kev ua tau zoo tshaj plaws, corrosion tsis kam, kev ua tau zoo-kub, thiab biocompatibility. Txawm li cas los xij, titanium alloys 'kuj tsis tshua muaj qhov chaw tawv tawv thiab tsis txaus hnav kev tsis kam txwv lawv cov ntawv thov hauv ib puag ncig. Txhawm rau txhim kho cov cuab yeej no, cov kws tshawb nrhiav tau tsim ntau hom kev kho mob ntawm kev kho kom zoo rau kev txhim kho cov khoom saum npoo ntawm titanium alloys.
1. Nto Oxidation Kev Kho Mob
Qhov kev kho mob no txhim kho cov tshuaj tej titanium alloy nto los ntawm kev tsim cov yeeb yaj kiab oxide, txo cov nplaum thaum lub sijhawm kos duab.
2. Txheej kev kho mob
Graphite emulsion txheej
Ua ntawv thov graphite emulsion ua ntej kos duab kub tsis tsuas yog siv lubrication tab sis kuj tiv thaiv lub billet deg los ntawm oxidation. Graphite emulsion cov ntsiab lus ntawm 20% -25%, ib qho loj me ntawm 1-3 μm, thiab cov khoom nplaum zoo nkauj rau lub billet saum npoo {}} ntsev kua quav
Qhov tshwj xeeb tsim ntsev kua txiv roj hmab roj nplua nyeem yog siv, xws li muaj kev sib xyaw ntawm 125% Cao, 0.3% NauleSsed Plab Plua Plav Dej, 0.2% NauleSp, thiab cov hmoov nplej siab thiab 25% leejpFF hmoov.
- Cov tshuaj fluorophosphathaphathaphate
Tom qab lub cev tu cov hlau khoob khoob khoob, cov nplaim hluav taws xob tau muab cov roj nplua nyeem los ua cov nyhuv khov kho kom ua tiav cov nyhuv ntawm lubricating nrog cov kev sib txhuam ntawm lubricating thiab lub siab hnav tsis kam.
3. Metallization
Ib co txheej hlau, xws li tooj liab, chromium, thiab Tin, yog siv rau cov txheej txheem titanium allloy, yog li rho adchesion.
4. Boration
Titanium alloy xaim yog raus rau hauv cov tshuaj sib tov uas muaj kfb₄, baclun, thiab nh₄no₃, rhuab mus rhaub, thiab tom qab ntawd raus. Tom qab tshem tawm, ntxuav, thiab kom qhuav, ib txheej fluorobatorate yog tsim rau ntawm cov hlau nto. Thaum lub sij hawm taub txias, ib txheej ntawm txhuas disulfide tseem siv rau cov xaim hluav taws xob raws li cov roj nplua nyeem . 5.} kev kho tshuaj hloov pauv
Kev Kho Mob Hloov Siab Txheem Hloov Cov Lus Txheej Txheem Hloov Khoom Sib Tham Ua Si ntawm cov titanium alloy nto. Zaj yeeb yaj kiab no ua lubricating txheej, nqus lubricants thiab ua kom cov txheej txheem du tom qab ntau daim duab hla, tsis muaj adcesion lossis xaub cim.
6. Cov roj nplua nyeem xaiv
Xaiv cov kua nplaumant, xws li xum xab npum hmoov, graphite emulsion, lossis sib tov ntawm xab npum hmoov thiab lwm yam khoom siv. Cov roj nplua nyeem yuav tsum muaj kev nthuav dav zoo thiab thermal stability nrog cov txheej.
7. Laser nto kev kho mob
Laser kho technologies, suav nrog laser cladding, laser nto quenching, thiab hardness tsis kam, thiab tawv tawv los ntawm kev kho microstructure ntawm txheej saum npoo av ntawm txheej saum npoo av. Qhov zoo ntawm kev kho laser yog tias nws tuaj yeem txhim kho cov khoom saum npoo av tsis muaj kev hloov pauv ntawm titanium alloy substrate.
8. Micro-arc oxidation
Cov txheej txheem no suav nrog hauv-situ txoj kev loj hlob ntawm cov lus teb ceramic nyob rau saum npoo titanium alloy, tsim cov yeeb yaj kiab ua yeeb yam nrog kev ua yeeb yam cerosion thiab hnav tsis kam. Kev Siv Tshuab Micro-Axidation yog ib puag ncig phooj ywg thiab zoo sib xws nrog cov tswv yim txhim kho kom ruaj khov {3} ion ion ion ion
Los ntawm Implanting ntsiab xws li nitrogen, oxygen, thiab carbon rau saum npoo ntawm titanium alloy, lub ntsej muag zoo nkauj thiab coj kev yuav txhim kho. Lub ion ion implantation txheej, feem ntau ntawm qib nanometer, tuaj yeem txhim kho cov khoom saum npoo av ntawm cov titanium alloy.
10. Thermal diffusion
Los ntawm diffusing alloy cov ntsiab lus rau hauv titanium alloy nto ntawm qhov kub, ib txheej yog tsim, yog ib txheej yog tsim cov npoo tawv thiab hnav tsis kam.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
