NiCrBSi

WOCO identifies this item as NiCrBSi thermal spray powder, model / grade NiCrBSi.

Some source size units are inconsistent with the powder designation. Confirm the required particle size and product form against the original record.

The source material field reads: Cr17.5%,Fe4.31%,B3.6%,Si4.5%,Ni Balance.

Listed manufacturing route: Agglomerated & sintered.

Application & selection

Nickel-based self-fluxing powders use boron and silicon as part of the alloy system. The supplied notes discuss their roles in wetting, deoxidation and slag formation, and describe nickel-based powders in laser-cladding and surface-repair work.

Select the composition around the substrate and deposition route. The powder, process heat input and finishing requirements need to be considered together; a grade name alone is insufficient to establish the final coating hardness, dilution or corrosion behaviour.

Details to confirm for this product

• Grade chemistry, boron and silicon requirements and size distribution.
• Substrate, deposition route and finishing allowance.
• Required coating tests and limits on dilution or defects.
