Black Electroless Nickel (Tacti-black) Services

Black Electroless Nickel Plating Services – Tacti-Black Electroless Nickel

GB3_2791Advanced Plating Technologies offers a proprietary black electroless nickel plating – Tacti-black electroless nickel – which combines the exceptional lubricity, deposit uniformity, hardness and corrosion resistance of electroless nickel with a fully conductive and uniform black appearance.  APT’s black electroless nickel plating is currently utilized in a wide range of industries including the firearm, defense, interconnect, telecommunications and aerospace industries.

APC Photos 28Dec12 0082Advanced Plating Technologies’ black electroless nickel plating is available in both medium and high phosphorus varieties.  The level of phosphorus in the coating affects the deposit appearance and properties similar to traditional electroless nickel deposits.  In addition, post-plate baking can transition the deposit from an amorphous to crystalline structure, which greatly increases the deposit hardness.

A brief summary of the deposit properties for our black electroless nickel plating is provided below:

Black Electroless Nickel Plating, High Phosphorus (>10% P):  Semi-bright to matte charcoal gray appearance, non-magnetic with good solderability and highly corrosion resistance with adequate deposit thickness.

black-upperBlack Electroless Nickel Plating, Medium Phosphorus (6-9%P):  Semi-bright to bright appearance with a satin black appearance, magnetic, good to excellent solderability and moderate corrosion resistance with adequate deposit thickness.

APT’s Black electroless nickel plating process produces a deposit that is fully conductive and can be soldered or brazed to make it suitable for interconnect, electronics and EMI grounding/shielding applications.  It provides good temperature stability suitable for service temperatures up to 600F with short duration exposures up to 700F.  It provides the perfect deposit uniformity of traditional electroless nickel with tolerances of less than one ten-thousandth of an inch per side possible.

The appearance of the black electroless nickel plating process is a function of the luster of the substrate as well as the phosphorus content of the deposit.  The blackest and brightest appearance is achieved with a highly lustrous (polished) substrate and a medium phosphorus Tacti-black electroless nickel plating.  Conversely, a gray and matte appearance is achieved with a fully matte (such as sand-blasted) substrate with a high phosphorus Tacti-black electroless nickel plating process.  At this time, a jet-black and fully matte appearance cannot be achieved with Tacti-black electroless nickel.

GB3_2798Advanced Plating Technologies’ Tacti-black black electroless nickel plating provides excellent wear resistance consistent with traditional electroless nickel.  However, the black appearance can be worn through in aggressive wear points such as metal-on-metal sliding contact.  Therefore, the application of the finish for high wear applications should be evaluated accordingly.

Advanced Plating Technologies provides expertise in black electroless nickel plating services to fulfill even the most demanding applications.  From prototyping and PPAP qualification to full production processing, it is APT’s goal to exceed your expectations.  The following points highlight why Advanced Plating Technologies is a leader in black electroless nickel plating:
