Nto Diffusion thiab Ion Implantation
Tsis zoo li deg nano-kho, nto diffusion thiab ion implantation dope hlau los yog cov ntaub ntawv uas tsis yog-hlau rau hauv titanium alloy matrix khoom, hloov nws deg qauv muaj pes tsawg leeg, thiab txhim kho nto kuj ntawm titanium alloy matrix los ntawm kev hloov txheej. Piv txwv li, qhov saum npoo ntawm titanium thiab titanium alloy yog permeated los ntawm non-metallic cov ntaub ntawv xws li nitrogen thiab carbon, los yog diffused los ntawm hlau cov ntaub ntawv xws li txhuas thiab molybdenum, yog li txhim kho cov hnav tsis kam thiab corrosion kuj ntawm titanium alloy matrix. Kev tiv thaiv corrosion ntawm TC4 substrate tuaj yeem txhim kho tau zoo los ntawm kev nkag TA ntawm qhov chaw ntawm TC4 substrate los ntawm reticular cathode glow paug txoj kev.
Cov txheej txheem saum npoo ntawm TC6 tuaj yeem hloov pauv tau zoo heev los ntawm kev siv cov hmoov sib xyaw ua ke thiab cov txheej txheem ntawm kev npaj molybdenum infiltrated txheej kom cov tawv tawv ntawm TC6 tuaj yeem nce mus rau 1400hv; Tam sim no, nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, kev tshawb fawb theoretical thiab kev ua haujlwm ntawm lub tshuab nqus tsev yog maj mam txhim kho. Ib qho ion implantation thev naus laus zis tuaj yeem muab tau los ntawm thawj qhov chaw nkag tshuab. Piv txwv li, qhov tawv tawv ntawm TA7 titanium alloy tuaj yeem nce mus rau 1200hv los ntawm ion nitriding. Lub hardness ntawm Ti6AI4V alloy kho los ntawm arc glow plasma hydrogen-dawb carburizing tshuab tuaj yeem ncav cuag 935hv thiab pom muaj zog hnav tsis kam.Ti6Al4V alloy tseem tuaj yeem kho los ntawm cov kua-theem plasma electrolytic carbonitriding thev naus laus zis los tsim Ti deposited tawv txheej ntawm cov hlau nplaum. Ua kom lub sij hawm kho mob ntawm titanium alloy nyob rau hauv txoj kev no tuaj yeem txhim kho lub thickness ntawm cov txheej txheem nyuaj infiltration thiab txhim kho qhov hnav tsis kam ntawm titanium alloy.
Nto Txheej Technology
Qhov saum npoo ntawm cov khoom siv hauv paus yog kho los ntawm cov txheej txheem sib xws. Cov txheej txheem sib xyaw thiab cov khoom siv hauv paus tsim cov txheej txheem tiv thaiv ntawm cov khoom siv hauv paus, uas muaj cov khoom zoo hauv chemistry, cua sov, thiab lwm yam. Nrog kev pab los ntawm corrosion kuj thiab kub tsis kam ntawm txheej txheej, cov nqi tsim khoom tuaj yeem txo qis, txhawm rau txhim kho cov khoom lag luam thiab muaj kev pabcuam ntev hauv kev siv tom ntej. Tam sim no, txheej txheej txheej txheej txheej ntawm vapor deposition thiab cladding tuaj yeem txhim kho qhov hnav tsis kam ntawm titanium alloy thiab muaj zog tiv thaiv corrosion. Kev sib koom ua ke ntawm cov organic ua kom lub ntsej muag thiab kev kho hydrogenation tuaj yeem txhim kho qhov chaw ua haujlwm ntawm titanium alloy thiab zam cov khoom xeb tom qab kev sib cuag nrog cov dej nag. Siv cov tshuab vapor deposition, TA2 thiab TC11 substrates yog tsim rau hauv TiAIN zaj duab xis, uas tuaj yeem tsim cov metallurgical ua ke ntawm peb lub ntsiab hauv kev sib txuas ntawm zaj duab xis thiab cov substrate, thiab txhim kho ntau yam khoom ntawm lub substrate.
