Ntsiab lus thiab kev tshuaj ntsuam xyuas ntawm kev tshawb fawb ntawm Brazing ib-txheej pob zeb diamond cov cuab yeej:

1. Kev tshawb fawb ntawm Brazing alloys

◎ Cov neeg npib tsib xee nyob hauv alloys

- dav siv, xws li ni-cr alloys (muaj cr, b thiab nqus dej (1050 degree {{

- Switzerland siv nplaim taws ua ke nrog Argon Shield Brazing, thiab lub teb chaws Yelemees qhia tias nws cov cuab yeej sib tsoo yog ntau tshaj li ntawm cov cuab yeej hluav taws xob.

- Nanjing University of Aeronautics thiab Asternonautics nyob rau hauv Tuam Tshoj paub tseeb tias txheej txheem carbide yog tus yuam sij rau kev sib raug zoo los ntawm kev ntsuas kev tawm tsam.

◎ Nyiaj-raws li alloys

◎ Ag-Cu-Ti Brazing muab tub lim (xws li Ag67% -T2012%) tsim lub zog ntawm lub tshuab nqus tsev nce 133mpa (harbin lub koom haum ntawm thev naus laus zis).

◎ Ag-Cu alloy nrog Cruced tuaj yeem tsim tau rau hauv huab cua, thiab cr₃c₂ yog tsim nyob rau hauv graphitation ntawm cov kub (Nanjing University of Aeronautics thiab Asternautics).

‡ Hawm los tooj liab-ua alloys

◎ Cu-Sn-Ti-ZR thiab lwm yam alloys raug ntsia hauv lub tshuab nqus tsev (930 degree) los ua ib tug multilayer Tic qauv. Xi'an Jiaotong University's COPPING-Raws cov khoom siv muaj qhov kub tsawg, txo cov thermal kev puas tsuaj los ntawm cov khoom siv abrasive, thiab muaj dav dav.

Taiwan University sib piv cov nqus dej thiab pom tias lub tshuab nqus tsev ua cov yeeb yaj kiab txuas ntxiv, thaum cov txheej txheem laser tsuas yog tsim cov txheej txheej tsis sib xws.

2. Brazing txheej txheem thiab parameter optimization

◎ Txheej Txheem Txheej Txheem

◇ High-zaus Induction Induction Induction: Ceev ceev rau kaum ntawm vib nas this), yuav tsum muaj alloys roj av, yuav tsum muaj kev tiv thaiv kab mob sib cav, yuav tsum muaj kev tiv thaiv kev sib cav, yuav tsum muaj kev tiv thaiv kab mob sib cav, yuav tsum muaj cov pa roj ntsha lossis tiv thaiv hauv zos.

Lub tshuab nqus tsev ua kom sov qwj: Kev tswj qhov ntsuas kub (xws li 920 degree {1}}}} feeb), thiab kev tiv thaiv ntawm pob zeb diamond los ntawm oxidation.

◇ Laser Brazing: kev sim ntawm Taiwan University qhia tau tias nws yog qhov ua tiav (ua tiav hauv 10 vib nas this), tab sis txuas ntxiv ntawm cov txheej txheem carbide yog neeg pluag.

◎ Cov Ntsiab Lus Tseem Ceeb

◇ Kub (kub heev yuav ua rau graphitization ntawm pob zeb diamond (piv txwv li, ag-cu-ti soldering muaj zog ntawm 940 degree).

Braining Lub Sij Hawm Lub Tsev: Alloys Tsev Kho Mob yuav tsum muaj sijhawm luv (6-30}}}}}}}} kev sib cais) los tiv thaiv kev sib cais ntau dhau; Tooj liab-ras alloys yuav tsum tau 10 feeb los xyuas kom meej cov tshuaj tiv thaiv txaus txaus.

◇ Cov huab cua tiv thaiv: Argon lossis nqus ({{{{}}. 2pa}} 10} 10} 10}} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10} 10}} 10} 10} 10} × × 10}}}}} × 10⁻ 10.

3. Interface cov tshuaj tiv thaiv thiab kev sib cais

Cov khoom siv sib hloov (TI

Solfusion thiab kev txhawb nqa ntawm CR nyob rau hauv Nickel-based cov neeg muag yog tus yuam sij, thaum cov khoom siv nyiaj siv ntawm Ti.

◎ morpome ntawm carbides ntawm lub interface cuam tshuam rau lub zog uas muaj zog. Piv txwv li, kev tua phom tua phom thiab flake cr₃c₂ muaj cov teeb meem sib txawv ntawm kev sib raug zoo ruaj khov.

4. Abrasive b grag txoj kev txhim kho kev kho tshuab

◎ Lub Hom Phiaj: Ua kom nce qhov chaw, txo qhov kev sib tsoo, thiab txuas ntxiv kev ua haujlwm ntawm lub neej (piv txwv li kev ua tau zoo ntawm lub pob zeb diamond thiab ob chav txiav ceev).

◎ Txoj Kev Siv

◇ replication Technology: Si Template luam tawm cov pob zeb diamond ua yeeb yaj kiab, haum rau me me-loj abrasives.

◇ Plhaub cov kev faib tawm cov qauv: Refractory txheej ua ntej-sau ua ntej kom sau cov nplej brazing thiab abrasive, haum rau cov khoom nkhaus sab npoo av.

◇ Laser sai sai: Siv cov ntaub ntawv Laser Scanning rau tsau-point branzing, nrog siab prepision tab sis tus nqi siab.

5. Kev sib piv ua tau thiab siv tau

Piv txwv nrog electroplating thiab sintering cuab yeej, cov abrasive grain tau txhim kho, thiab lub pob zeb diamond ua kom txo qis.

Cov Ntaub Ntawv Kuaj:

Lub neej ntawm Brazed pob zeb diamond sib tsoo muaj ntau dua 3 zaug uas muaj hluav taws xob sib tsoo, thiab cov kev sib tsoo hluav taws xob loj yog txo los ntawm 30% {}}}%.

◇ Qhov ua tau zoo ntawm ib-txheej tau txais cov roj tau kaw los ntawm kev ua cov cuab yeej pob zeb yog 4.9 zaug ntawm cov cuab yeej electroplated.

6. Tam sim no cov kev sib tw thiab yav tom ntej cov lus qhia

Txheej Txheem Nyuaj taus: Kev ua siab zoo tswj hwm ntawm pawg ntau lawm stability, xws li kev faib tawm ntawm micro-hmoov-qib pob zeb diamond).

◎ Cov Lus Taw Qhia:

Kev Txhim Kho Cov Khoom Siv Hluav Taws Xob (xws li ntxiv cov khoom tsis tshua muaj txiaj ntsig rau kev tswj hwm tsis zoo).

◇ Kev Siv Lub Tshuab (Laser Brazing sai prototyping, kev tshawb nrhiav thiab kev ua kom tsis zoo ntawm cov khoom siv).

◇ Expland cov chaw thov roj (xws li roj laum roj, kev ua tiav ceramis kev ua tiav, thiab lwm yam).

Kev Tshawb Fawb Txog Kev Tshawb Fawb

Cov cuab yeej siv hluav taws xob ntau tshaj qhov kev ua tau zoo ntawm ib leeg-txheej pob zeb diamond tshuaj txawv, thiab cov nyiaj npib nyiaj, thiab tooj liab brazing txhua yam muaj lawv tus kheej.

Yav tom ntej, peb yuav tsum tau kov yeej cov kev nyuaj ntawm kev ua kom zoo dua qub, thiab txhawb nws cov ntawv thov thoob plaws hauv kev ua haujlwm siab.
