Kev Ua Haujlwm thiab Kev Pabcuam Kho Kom Zoo Nkauj ntawm Cov Phaj Uas Siv Overlay

Hauv kev tsim khoom lag luam niaj hnub no, CCO hnav phaj (chromium carbide overlay hnav-resistant phaj) siv dav hauv cov chaw hnav khaub ncaws siab xws li kev khawb av, cov khoom siv hauv tsev, hlau, thiab hluav taws xob vim nws txoj kev tiv taus hnav zoo heev thiab kev hloov pauv ntau yam. Nws yog ua los ntawm cov hlau carbon siab chromium welded rau ntawm qhov chaw ntawm cov hlau carbon qis, tsim cov qauv sib xyaw ua ke bimetallic hnav-resistant nrog kev tawv thiab tawv, uas tuaj yeem ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab txo cov nqi txij nkawm. Tsab xov xwm no yuav qhia txog cov khoom sib xyaw, cov yam ntxwv kev ua tau zoo, thiab cov kev pabcuam ua tiav ntawm CCO hnav phaj los pab cov neeg siv nkag siab zoo dua thiab siv cov khoom siv no.

Cov khoom sib xyaw ntawm cov phaj overlay hnav-resistant

Cov hlau nplaum uas muaj cov pa roj carbon ntau thiab cov chromium ntau yog cov khoom tseem ceeb ntawm cov hlau no.CCO hnav phaj. Nws lub ntsiab tivthaiv tuaj yeem tsim ntau Cr7C3 carbide nyuaj nyob rau hauv qhov kub thiab txias thiab siab, tsim cov qauv eutectic + M7C3. Cov qauv no txiav txim siab nws qhov kev tiv thaiv zoo heev, uas tseem ruaj khov txawm tias nyob rau hauv cov chaw hnav khaub ncaws nyuaj. Txhawm rau txhim kho qhov kev ua tau zoo tag nrho, cov khoom siv micro-alloy xws li molybdenum, tungsten, vanadium, boron, thiab niobium kuj tseem tuaj yeem ntxiv rau cov khoom siv los txhim kho qhov kub thiab txias, kev cuam tshuam, thiab kev tiv thaiv corrosion.

Cov carbides M7C3 raug teeb tsa ntev hauv qab cov qauv me me. Cov qauv no tseem tuaj yeem ua tau zoo nyob rau hauv qhov kub siab lossis kev sib txhuam hnyav, ntau dua li cov hlau ib txwm.

Kev ua tau zoo ntawm lub phaj overlay hnav-resistant

Kev tiv taus kev cuam tshuam yog ib qho ntawm cov qauv tseem ceeb rau kev txiav txim siab qhov zoo ntawm cov phaj uas tiv taus kev hnav. Cov txheej txheem sib txuas hlau ntawm CCO phaj uas tiv taus kev hnav ua rau cov txheej npog ruaj khov rau ntawm cov phaj hlau, tsis yooj yim poob tawm, thiab tseem ruaj khov thiab txhim khu kev qha txawm tias muaj kev cuam tshuam loj lossis kev thauj khoom ntau.

Cov phaj CCO tuaj yeem ua tiav kev faib ua feem meej los ntawm laser, plasma, thiab tseem tuaj yeem ua tiav ntau yam, xws li khoov txias, drilling, vuam, thiab lwm yam, yam tsis muaj zog ua rau lawv tsis kam hnav. Piv txwv li, 5 + 5 overlay hnav phaj (5 hli substrate + 5 hli cladding txheej) yog ib hom qauv, uas tsis tsuas yog khaws cov qauv muaj zog tab sis kuj suav nrog kev lag luam thiab kev ua haujlwm yooj yim.

Kev pabcuam ua phaj overlay uas tiv taus kev hnav

Thaum muab cov khoom siv phaj uas tsis yooj yim hnav CCO, Wodon kuj tseem yuav muab cov kev pabcuam ua tiav. Hais txog kev txiav, cov khoom siv plasma lossis laser siv rau kev txiav siab, uas tsis yog tsuas yog ua haujlwm tau zoo thiab muaj thaj chaw me me uas cuam tshuam los ntawm cua sov, tab sis kuj muaj cov khoom tiav zoo heev.

Piv txwv li, hais txog kev khoov thiab kev tsim, cov hlau sib xyaw ua ke uas tsis yooj yim hnav tuaj yeem ua tiav txias rau hauv cov khoom nkhaus lossis conical kom tau raws li qhov xav tau ntawm cov khoom siv nyuaj. Cov kev pabcuam drilling suav nrog qhov ncaj thiab qhov countersunk ua tiav, uas yooj yim rau kev sib txuas bolt tom qab lossis kev teeb tsa vuam. Tsis tas li ntawd, hom phaj hnav no muaj weldability zoo thiab tuaj yeem siv los ua cov khoom hnav xws li cov thoob excavator, liners, thiab conveyor system bushings.

Kev pabcuam tshwj xeeb

Xav txog qhov sib txawv ntawm cov kev xav tau ntawm ntau yam lag luam thiab cov khoom siv rau cov ntaub ntawv hnav-resistant, Wodon kuj muab cov kev daws teeb meem loj me uas hloov kho tau. Lub thickness ntawm cov txheej surfacing, qhov loj ntawm cov phaj, thiab lwm yam kev ntsuas tuaj yeem hloov kho raws li tus neeg siv xav tau kom ntseeg tau tias cov khoom raug phim nrog daim ntawv thov tiag tiag. Piv txwv li, hauv daim ntawv thov ntawm kuv cov kav dej xa khoom, cov txheej surfacing tuab thiab cov phaj sib xyaw tiv thaiv corrosion tuaj yeem muab los ua kom lub neej ua haujlwm ntev dua.
