Ntu 2: Anodizing
Anodizing feem ntau yog anodizing ntawm txhuas, uas siv cov txheej txheem electrochemical los tsim ib qho Al2O3 (txhuas oxide) zaj duab xis rau saum npoo ntawm txhuas thiab txhuas alloys.Cov oxide zaj duab xis no muaj cov khoom tshwj xeeb xws li kev tiv thaiv, kho kom zoo nkauj, rwb thaiv tsev, thiab hnav tsis kam.
Qhov zoo: Cov yeeb yaj kiab oxide muaj cov khoom tshwj xeeb xws li kev tiv thaiv, kho kom zoo nkauj, rwb thaiv tsev, thiab hnav tsis kam.
Cov ntawv thov: xov tooj ntawm tes, khoos phis tawj thiab lwm yam khoom siv hluav taws xob, khoom siv kho tshuab, dav hlau thiab tsheb qhov chaw, cov cuab yeej precision thiab cov khoom siv hauv xov tooj cua, cov khoom siv niaj hnub thiab kev kho vaj tse.
Cov ntaub ntawv siv tau: aluminium, aluminium alloy thiab lwm yam khoom siv txhuas
Ntu Peb: Electroless Nickel Plating
Electroless npib tsib xee plating, tseem hu ua electroless npib tsib xee plating, yog txheej txheem ntawm kev tso ib txheej npib tsib xee rau ntawm qhov chaw ntawm lub substrate los ntawm cov tshuaj txo cov tshuaj tiv thaiv tsis muaj lwm yam tam sim no.
Qhov zoo: Qhov zoo ntawm cov txheej txheem no suav nrog kev ua haujlwm zoo corrosion, hnav tsis kam, zoo ductility thiab hluav taws xob khoom, thiab siab hardness tshwj xeeb tshaj yog tom qab kev kho cua sov.Tsis tas li ntawd, cov txheej txheej electroless npib tsib xee plating muaj qhov zoo weldability thiab tuaj yeem tsim cov tuab tuab thiab cov ncauj lus kom ntxaws hauv qhov tob, grooves, thiab cov ces kaum thiab cov npoo.
Cov ntaub ntawv siv tau: Electroless nickel plating yog tsim rau npib tsib xee plating ntawm yuav luag txhua qhov chaw hlau, suav nrog hlau, stainless hlau, txhuas, tooj liab, thiab lwm yam.
Part 4: Stainless hlau passivation
Cov txheej txheem ntawm passivating stainless hlau yuav reacting stainless hlau nto nrog ib tug passivating tus neeg sawv cev los tsim ib tug ruaj khov passivation zaj duab xis.Cov yeeb yaj kiab no tuaj yeem txo qhov corrosion ntawm stainless hlau thiab tiv thaiv cov khoom siv los ntawm oxidation thiab corrosion ua rau xeb.Kev kho mob Passivation tuaj yeem ua tiav los ntawm ntau txoj hauv kev, suav nrog tshuaj lom neeg passivation thiab electrochemical passivation, feem ntau yog kev kho mob nrog cov oxidants muaj zog lossis cov tshuaj tshwj xeeb.
Qhov zoo: Lub passivated nto ntawm stainless hlau muaj zog tiv thaiv pitting corrosion, intergranular corrosion thiab abrasion corrosion.Tsis tas li ntawd, kev kho mob passivation yog yooj yim rau kev khiav lag luam, yooj yim rau kev tsim, thiab tus nqi qis.Nws yog tshwj xeeb tshaj yog haum rau loj-thawj painting los yog soaking ntawm me me workpieces.
Cov ntaub ntawv siv tau: ntau hom stainless hlau cov ntaub ntawv, suav nrog tab sis tsis txwv rau austenitic stainless hlau, martensitic stainless hlau, ferritic stainless hlau, thiab lwm yam.
GPM's Machining Peev Xwm:
GPM muaj kev paub dhau los hauv CNC machining ntawm ntau hom precision qhov chaw.Peb tau ua haujlwm nrog cov neeg siv khoom hauv ntau qhov kev lag luam, suav nrog cov khoom siv hluav taws xob, khoom siv kho mob, thiab lwm yam, thiab tau cog lus los muab cov neeg siv khoom zoo, cov kev pabcuam machining zoo.Peb tau txais kev tswj hwm nruj nruj kom ntseeg tau tias txhua feem ua tau raws li cov neeg siv khoom xav tau thiab cov qauv.
