Qhov zoo ntawm cov kub kub tshuaj nickel rau lub tshuab nqus tsev electroplating hluav taws xob cua sov raj

1. Nws tuaj yeem tso rau saum npoo ntawm ntau yam ntaub ntawv, xws li: steel nickel-based alloys, zinc-based alloys, aluminium alloys, iav, ceramics, plastics, semiconductors, thiab lwm yam., tsim cov xwm txheej rau kev txhim kho cov ntaub ntawv no. .

2. Hauv kev ua haujlwm ntawm ntau cov ntaub ntawv thiab qhov chaw, xws li corrosion kuj, hnav tsis kam, kub oxidation tsis kam, thiab lwm yam, electroless npib tsib xee plating yog zoo dua electroplating nickel.

2. Muaj peev xwm pov tau zoo thiab cov tuab tuab ntawm cov txheej yog ib qho tseem ceeb ntawm electroless nickel plating. Tsis zoo li electroplating npib tsib xee, lub thickness ntawm txheej yog tsis sib npaug vim tsis sib xws tam sim no faib. Nyob rau hauv tus txheej txheem ntawm electroless npib tsib xee plating, ntev li ntev raws li qhov saum npoo ntawm ib feem yog nyob rau hauv kev sib cuag nrog cov plating tov, thiab cov khoom noj nyob rau hauv lub plating tov yuav tsum tau replenished nyob rau hauv lub sij hawm, lub thickness ntawm lub plating txheej ntawm lub plated qhov chaw yog yeej. tib yam, txawm tias cov grooves, qhov khoob, thiab qhov muag tsis pom qhov zoo ib yam.

4. Kev kho cua sov tsawg. Lub workpiece tom qab electroless npib tsib xee plating tuaj yeem tau txais kev sib txawv corrosion thiab hnav tsis kam tom qab raug kho nrog lub sijhawm tuav sib txawv hauv qab 400 degree. Yog li ntawd, electroless npib tsib xee plating yog tshwj xeeb tshaj yog haum rau qhov chaw nrog complex duab thiab siab nto hnav tsis kam thiab corrosion kuj.

Lub expansion coefficient ntawm aluminium alloy thiab aluminium yog loj dua lwm yam hlau

1 Aluminium alloys yog yooj yim heev los tsim oxide zaj duab xis nyob rau hauv cov huab cua, thiab ib zaug no oxide zaj duab xis raug tshem tawm, ib tug tshiab oxide zaj duab xis yuav raug tsim nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm, uas yuav cuam tshuam rau lub bonding quab yuam ntawm txheej thiab ua rau delamination. .

2 Lub peev xwm electrode ntawm txhuas yog qhov tsis zoo, thiab thaum muab tso rau hauv cov tshuaj electroplating, nws yooj yim los hloov nrog cov hlau ions nrog lub peev xwm zoo, uas cuam tshuam rau qhov adhesion ntawm txheej.

3 Lub expansion coefficient ntawm aluminium alloy thiab aluminium yog loj dua li ntawm lwm yam hlau, yog li nws tsis haum rau electroplating nyob rau hauv ntau yam ntawm kub hloov. Aluminium alloy thiab aluminium thiab lwm yam hlau coatings muaj qhov sib txawv expansion coefficients, uas yuav ua rau muaj kev ntxhov siab ntau dua, kom lub zog sib txuas ntawm cov txheej thiab aluminium thiab aluminium alloys tsis muaj zog.

4 Aluminium yog cov hlau amphoteric, soluble hauv cov kua qaub thiab alkali, thiab tsis ruaj khov hauv cov kua qaub thiab alkali electroplating daws.

5. Kev tuag-casting aluminium alloys yog qhov ua rau hlwv thiab qhov pores tom qab tuag-casting, tawm hauv plating tov thiab hydrogen roj, yooj yim bubbling, thiab kuj txo cov kev sib raug zoo ntawm cov txheej thiab lub hauv paus hlau, yog li pretreatment tseem ceeb heev.
