• Electroless deposition of NiP on a silicon surface ...

     · The present article concerns the metallization of silicon substrates by deposition of the nickelphosphorus alloy produced by an autoalytic chemical process. The deposition electrolyte is composed of a metal salt, a reducing agent (sodium hypophosphite), a complexing agent (sodium citrate) and a buffer (ammonium acetate). The deposition could only be carried out after activation of the ...

  • MacDermid Enthone | Electroless Nickel | Properties

    Hypophosphite reduced electroless nickel is one of the very few metallic glasses used as an engineering material. Depending on the bath formulation, deposits may contain from 1% (low phosphorous nickel) to 13% (high nickel phosphorus). Although electroless nickel boron plating to AMS 2433 is also an option, phosphorus is the most common alloy.

  • Plating: the role of nickel | Nickel Institute

    Electroless nickel plating. In electroless nickel plating, a nickel coating is deposited on a surface using a controlled chemical process, or 'reduction', which is not based on an applied current. This is why electroless nickel coatings are extremely uniform, even when applied to items with a complex shape.

  • A simple nickel activation process for electroless nickel ...

    Abstract. A new nickel activation process was developed for metalizing the carbon fiber (CF) surface with electroless nickel plating. The oxidation and activation processes were examined using Xray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), Energy Dispersive Xray Spectrometry (EDS), and Xray Diffractometry (XRD).

  • Die Casting Surface Finishes | Electroless Nickel Plating

     · There are three types of electroless nickel: low phos, mid phos, and high phos. Low phos – has a thickness of .0011". It is a hard deposit approaching hard chrome with no heat treatment necessary for hardness. It is comparable to boron electroless nickel. This deposit is used mainly for its hardness and wear properties.

  • Analyzing and Controlling Electroless Nickel Baths

     · The nickel layer's structure and the phosphorous content are key factors in determining subsequent black pad formation, with these factors related to the pH and composition of the bath used for electroless nickel deposition. Therefore, the key to defectfree ENIG processes is maintaining precise control of the electroless nickel bath.

  • Method for electroless nickel plating on the surface of ...

    Abstract. In this work, electroless nickel plating on the surface of CaCO 3 powders successively modified with stearic acid, oleamide and 3aminopropyltriethoxysilane in that order was developed. Hydrophobic and hydrophilic coatings were deposited onto the surface of the CaCO 3 powders in that order. On the one hand, the hydrophobic chains coated onto the surface of the modified powders .

  • Differences Between Electroless Nickel Plating Hard Chrome

    Substrate Surfaces Chrome and electroless nickel plating both work well for a variety of substrate materials. Because the coating deposits onto all surfaces of the component uniformly in the plating vat, you can use both metals for irregularly shaped objects, including those with holes and recesses.
