Ni-P + BN · Boron nitride composite coating
Smoother contact surfaces.
Low friction · self-lubricating · uniform coverage
Boron nitride particles are dispersed in a nickel-phosphorus matrix to provide lubrication for sliding surfaces. Choose systems with different phosphorus contents depending on whether wear or corrosion resistance is the priority.
BN particles provide lubrication; verify actual performance according to the friction pair, load, speed and lubrication method.

All contain BN, but the focus can differ.
Choose the nickel-phosphorus matrix according to wear, corrosion and lubrication needs, then confirm performance under actual service conditions.
Low-P Ni-P + BN
Focus on wear resistance, hardness and self-lubrication.
Discuss first: contact wear and sliding behaviorMid-P Ni-P + BN
Balances wear resistance, corrosion resistance and self-lubrication.
Discuss first: mechanical wear and environmental mediaHigh-P Ni-P + BN
Focus on corrosion resistance and self-lubrication.
Discuss first: corrosive media and lubrication needsThe above are qualitative directions from company data; specific phosphorus content, BN content and performance ranges for each grade must be confirmed separately.
02 / SLIDING APPLICATIONS
Start with "how it slides".
Confirming the friction pair, load, speed and lubrication method helps selection more than comparing a single friction coefficient.

- Pistons & sliding guides
- Focus on start-stop friction, operating temperature and lubrication supply; evaluate friction and wear of contact surfaces under actual load.
- Cutting tools & molds
- Focus on the contact material, surface sticking and operating temperature; determine thickness and verification method based on the actual part.
- Precision mating surfaces
- Focus on thickness distribution in holes, channels and complex shapes, as well as post-plating dimensions, roughness and assembly clearance.
03 / PERFORMANCE DATA
Values and conditions, read together.
Thickness is a range reference from the company's Ni-P + BN product data; specific coatings are selected according to the workpiece, phosphorus content and BN dispersion system.
| Item | Parameters & conditions |
|---|---|
| Typical thickness | 5–60 μmActual thickness, uniformity and fit dimensions are confirmed for the specific workpiece. |
Notes on temperature, substrate and functional verification
| Item | Parameters & conditions |
|---|---|
| Operating temperature | Confirm temperature limits according to the coating system, duration of use and atmosphere, and verify the fit between coating and substrate. |
| Applicable substrates | Company data lists steel, cast iron, copper alloys, aluminum and titanium; specific grades, pretreatment and adhesion are confirmed per part. |
| Conductivity & anti-static | If the application involves conductivity or anti-static requirements, test methods and targets must be agreed separately. |
| Chemicals & operating conditions | Request the TDS / SDS for the corresponding process according to the selected phosphorus content and BN dispersion system. |

| Coating type | Low-P Ni-P + BN | Mid-P Ni-P + BN | High-P Ni-P + BN |
|---|---|---|---|
| Coating characteristics | High wear resistance, high hardness, self-lubricating | Both wear and corrosion resistant, self-lubricating | High corrosion resistance, self-lubricating |
The functional focus of each system is listed per company data. Friction, hardness and service temperature must be verified for the selected process and actual conditions and are not a common guarantee for all three coatings.
