A. Electrolytic npib tsib xee yog tso siv DC tam sim no, thaum Tsis muaj hluav taws xob Ni yog autocatalytic deposition. Tsis muaj hluav taws xob Ni ua plating ntawm cov tuab tuab thoob plaws hauv ib feem, thaum electrolytic Ni daim hlau ua kom tuab dua nyob rau hauv qhov chaw siab tam sim no.

Ntxiv mus, nyuaj npaum li cas yog electroless nickel plating?

Raws li plated deposits ntawm electroless npib tsib xee plating tuaj yeem muaj qhov tseem ceeb hardness nyob rau hauv thaj tsam ntawm 450 - 750 VHN, nyob ntawm seb cov ntsiab lus phosphorus hauv qhov tso nyiaj. Feem ntau, qhov siab dua cov ntsiab lus phosphorus, qhov qis dua li deposited hardness.

Tsis tas li ntawd, puas yog electroless nickel plating kim? Electroless npib tsib xee yog feem ntau kim txheej txheem tshwj tsis yog rau cov hlau muaj nuj nqis plating.

Dab tsi yog electroless nickel plating siv rau?

Electroless npib tsib xee plating yog siv rau muab kev tiv thaiv los ntawm hnav thiab puas, tiv thaiv corrosion, thiab ntxiv hardness rau qhov chaw ntawm tag nrho cov mob. Nws yog feem ntau siv hauv coatings siv nyob rau hauv engineering, aerospace, roj thiab roj, kev tsim kho, electronics thiab ob peb lwm yam.

Dab tsi yog qhov txawv ntawm electroplating thiab electroless plating?

Cov lus teb yooj yim yog tias electro- plating siv hluav taws xob hauv txheej txheem ntawm kev hloov cov deposit mus rau ib tug substrate thaum electroless plating siv cov tshuaj aqueous thiab tsis muaj hluav taws xob hloov pauv qhov tso nyiaj.
