Farsamooyinka alxanka Carbide, Hababka, iyo Codsiyada Warshadaha

Carbiide sibidhka ah, oo caan ku ah engegnaantiisa gaarka ah (illaa 90 HRC) iyo xidhashada iska caabbinta, ayaa si weyn loogu dhex daray qalabka goynta, qashinka macdanta, iyo qaybaha saxda ah ee alxanka. Si kastaba ha ahaatee, jajabnaanteeda sare iyo isku dheelitirnaanta fidinta kulaylka ee aan isku dhigmin (TEC) ee leh substrates bir ah (4-7 × 10⁻⁶/°C vs. 11–13 × 10⁻⁶/°C) waxay keenaysaa caqabado alxanka gaarka ah. Maqaalkani wuxuu faahfaahinayaa tignoolajiyada alxanka ee ugu sarreeya, kontaroolada habka muhiimka ah, iyo codsiyada dhabta ah ee adduunka ee agabka carbide.

1. Farsamooyinka alxanka ugu sarreeya ee Carbide

Laba dariiqo ayaa ku jira ku biirista carbide warshadaha: brazing (caadi ah weli la isku halayn karo) iyo alxanka laysarka (xalka saxda ah ee sareeyo). Sifooyinkooda asaasiga ah ayaa hoos lagu barbardhigay:

▶ Brazing: Faraska Shaqada ee Soo saarista Qalabka Carbide

Brazing waxay ku gaadhaa isku xidhka iyadoo dhalaalaysa birta buuxinta (barta dhalaalka ka hooseeysa ee carbide/ birta) si ay u qoyso oo ay u buuxiso godadka wadajirka ah, iyada oo aan dhalaalin walxaha aasaasiga ah. Waa farsamada aasaasiga ah ee qalabka carbide sababtoo ah waxtarkeeda kharashka iyo ku habboonaanta wax soo saarka ballaaran.

Mabaadi'da Furaha & Xulashada Buuxinta

Habka Isku-xidhka: Biraha buuxinta dhalaalaysa waxa ay dhexgelisaa nusqaamaha-yar-yar iyada oo loo marayo ficilka xididdada, samaynta curaarta birta ah ee leh carbide (WC-Co) iyo substrates birta iyada oo loo marayo faafinta curiyaha (tusaale, Cr buuxintu waxa uu kaga falceliyaa C gudaha carbide si uu u sameeyo Cr₃C₂).

Aloyska Buuxinta:

Ni-Cr-Salaysan: Waxaa loo door bidayaa codsiyada kulaylka sarreeya (tusaale, qalabka wax lagu shiido), waxay dhalaalisaa 1050-1150°C, waxayna bixisaa iska caabin oksaydh oo heersare ah.

Ag-Cu-Salaysan: Waxaa loo isticmaalaa aaladaha cadaadiska hooseeya (tusaale, lathe gelinnada), waxay dhalaalisaa 650-800°C, waxay yaraynaysaa halista shoogga kulaylka.

Cu-Salaysan: Doorashada dhaqaale ee qalabka goynta ujeedo-guud, waxay u baahan tahay qulqul si looga saaro filimada oksaydhka.

▶ Alxanka Laser: Ku biirista saxda ah ee Qalabka Waxqabadka Sare

Alxanka Laser-ku wuxuu isticmaalaa laydh diiradda saaraya (1.06μm fiber laser doorbiday) si loo abuuro barkado dhalaalaysa oo gudaha ah, taasoo awood u siinaysa awood sare, kalagoysyada qallafsanaanta hoose. Waxay ku habboon tahay aaladaha-yar-yar iyo joomatariyada adag.

Faa'iidooyinka Farsamo ee ku Saabsan Brazing

Saamaynta Kulaylka Ugu Yar: Aagga kuleylku saameeyay (HAZ)

Habaynta degdega ah: Xawaaraha alxanka ilaa 50mm/s ee gashanaya carbide, 3x ka dhakhso badan brazing induction.

Xulashada Filler-free: Fiyuuska tooska ah ee qaybaha carbide ee gidaarka dhuuban (tusaale, qalabyada yaryar).

2. Caqabadaha Muhiimka ah & Xeeladaha Yaraynta

Guuldarrooyinka alxanka Carbide waxay asal ahaan ka yimaadaan walbahaarka haraaga ah iyo qoynta liidata. 

Xalalka la beegsanayo waa muhiim:

▶ Cadaadiska Haraaga & Dilaaca

Sababta Xididka: Is-dheellitir la'aanta TEC waxay sababtaa kala duwanaanshiyaha foosha kulaylka inta lagu jiro qaboojinta, taasoo dhalinaysa walbahaarka adkaysiga ee carbide.

Xalka:

Isticmaal lakabyada kaydinta dhexe (tusaale, Ni-Cu alloy) si aad u nuugo diiqada.

Qabo kuleyliyaha/qaboojinta (heerka kor u kaca ≤10°C/s) ee naxaasta gelinaysa.

Heerkulka alxanka ka dib 250C ilaa 2 saacadood si loo yareeyo walbahaarka 30-50%.

▶ Qoyaanka oo liita

Sababta Xididka: Tamarta sare ee Carbide waxay ka hortagtaa galitaanka birta buuxinta.

Xalka:

Kahor ku daawee karbidhida budada Cr si aad u samaysato lakab isku xidha Cr₃C₂.

Isticmaal qulqulo firfircoon (tusaale, borax-ku-salaysan) si aad uga saarto aflaanta oksaydhka ee birta

▶ Nabaadguurka birta wax lagu buuxiyo

Sababta Xididka: Kululaynta xad dhaafka ah waxay kala dirtaa xargaha carbide's Co, taasoo daciifisa wadajirka.

Xalka:

Ku xaddid wakhtiga alxanka ilaa

Xakamee muddada garaaca garaaca laysarka (2-5ms) si aad uga fogaato soo-gaadhista daba dheeraada.

3. Codsiyada Warshadaha & Daraasadaha Kiis

Alxanka Carbide wuxuu awood u siinayaa agabka waxqabadka sare leh ee qaybaha:

▶ Soo saarista Qalabka Goynta

Qalabka CNC Gelida: Faragelinta soo gelinta ee WC-Co gelintas ilaa shandado bir ah iyadoo la isticmaalayo buuxinta Ni-Cr-B-Si (1080°C, 45s) waxay ku guulaysataa 200MPa xoog wadajir ah—oo u adkaysta 5000rpm mashiinada.

Caleemaha Wareega: Alxanka laysarka otomaatiga ah (300W fiber laser) ee ilkaha carbide ilaa saxanadaha birta waxay yaraynaysaa heerka jabka iliga 60% vs. brazing.

▶ Macdanta & Dhismaha

Qodista Dhagaxa: Fakimaynta badhamada carbide ee jirka birta ah (Ni-Cr filler, 1120°C) waxay hubisaa iska caabbinta 50MPa culaysyada saamaynta; nolosha adeeg ayaa lagu kordhiyey 2-3x.

▶ Injineernimada saxda ah

Qalabka Mashiinnada-Mashiinka-Mashiinka: Alxanka laysarka Fiber-ka ee talooyinka carbide ee 0.8mm ee ulaha birta aan lahayn (250W, 15mm/s) waxay ilaalisaa saxnaanta cabbirka ± 0.01mm ee goynta wafer-waferka.

4. Isbeddellada Mustaqbalka

Alxanka Isku-dhafka ah: Isku-darka kuleylka hore ee laysarka iyo brazing induction si loo yareeyo dildilaaca karbidhida ee kala-goysyada qaybaha qaro weyn.

Kobcinta Filler Firfircoon: buuxinta Ni-Cr-Ti kuwaas oo sameeya xidhidhyo xoog badan oo TiC ah oo leh carbide, hagaajinta adkaysiga wadajirka ah 30%.

Is-dhexgalka Automation: Nidaamyada AI ay wado oo leh la socodka kulaylka-waqtiga-dhabta ah si loo wanaajiyo cabbirrada alxanka ee darajooyinka carbide ee doorsooma.

Gabagabo

Alxanka Carbide wuxuu u baahan yahay dheellitirka sayniska agabka iyo kontoroolka geeddi-socodka-brazing ayaa ka sarreeya wax-soo-saarka ballaaran ee kharash-ku-ool ah, halka alxanka laysarka uu xukumo codsiyada saxda ah ee muhiimka ah. Iyagoo wax ka qabanaya culayska haraaga ah iyo caqabadaha qoynta, soosaarayaashu waxay furi karaan kartida buuxda ee carbide ee xirashada sare, jawiga walaaca badan, laga bilaabo mashiinada warshadaha ilaa hawlgallada macdan qodista ee xad dhaafka ah.
