Tsis muaj teeb meem ntawm hydrogen embrittlement hauv electroless nickel plating ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj

Tsis muaj teeb meem ntawm hydrogen embrittlement. Electroplating yog hloov cov nickel cations rau hauv cov hlau npib tsib xee thiab tso lawv rau ntawm lub anode los ntawm kev siv fais fab mov. Cov txheej txheem ntawm kev txo cov tshuaj yog txo cov nickel cations rau hlau nickel thiab tso lawv rau saum npoo ntawm lub hauv paus hlau. Cov tshuaj tiv thaiv tsis muaj dab tsi cuam tshuam nrog cov txheej txheem electroplating. Feem ntau, cov ntsiab lus hydrogen nyob rau hauv cov txheej txheem nce nrog qhov nce ntawm qhov ceev tam sim no.

Thickness uniformity ntawm electroless nickel plating rau lub tshuab nqus tsev electroplating hluav taws xob cua sov raj

Uniform thickness thiab zoo sib xws plating muaj peev xwm yog ib qho tseem ceeb ntawm electroless npib tsib xee plating thiab ib qho ntawm cov laj thawj rau nws daim ntawv thov dav. Electroless npib tsib xee plating zam qhov tsis sib xws ntawm cov txheej txheej electroplating vim qhov tsis sib xws tam sim no. Qhov chaw, tshwj xeeb tshaj yog qhov chaw nrog cov duab sib txawv, txawv heev. Cov txheej yog thicker ntawm cov ces kaum ntawm qhov chaw thiab nyob ze ntawm lub anode, thaum lub txheej yog nyias nyias ntawm lub puab nto los yog nyob deb ntawm lub anode, los yog txawm tsis tau plated. Plating zam qhov tsis txaus ntawm electroplating. Thaum lub sij hawm electroless plating, ntev li ntev raws li qhov saum npoo ntawm ib feem yog nyob rau hauv kev sib cuag nrog cov plating tov, lub Cheebtsam noj nyob rau hauv lub plating tov yuav tsum tau replenished nyob rau hauv lub sij hawm, thiab lub thickness ntawm lub plating txheej nyob rau hauv tej qhov chaw yog yeej ib txwm zoo tib yam, txawm nyob rau hauv lub sij hawm. grooves, qhov khoob, thiab qhov dig muag qhov.

Cov yam ntxwv cuam tshuam rau Internal Stress ntawm Electroplating ntawm Nqus Electroplating Hluav Taws Xob Cua Kub Tube

Muaj ntau yam cuam tshuam rau kev ntxhov siab sab hauv ntawm txheej txheej, feem ntau yog cov txheej txheem electroplating thiab cov txheej txheem daws teeb meem, hom khoom siv matrix, thiab lwm yam, uas sib txawv los ntawm compressive kev nyuaj siab mus rau tensile stress. Macroscopic sab hauv kev ntxhov siab yuav ua rau micro-nrawm thiab pores hauv txheej, txawm tawg, tev, thiab lwm yam, thiab tseem yuav muaj kev cuam tshuam tsis zoo rau lub zog sib txuas ntawm txheej; tensile kev nyuaj siab kuj tseem yuav txo tau qhov qaug zog ntawm lub hauv paus hlau, xws li kev nyuaj siab chrome plating tuaj yeem txo cov hlau. Lub zog qaug zog yog 22 feem pua ​​​​rau 73 feem pua.
