The Structure and Wear Resistance of Ni P BN w Electroless Composite Coating

The wurtzite boron nitride (BN w) ultrafine powder was synthesized using the detonation method, the Ni P BN w electroless composite coating was prepared, and their structure and wear resistance were studied. Experimental results show that when BN w particles was added to Ni P electroless coating, it did not change the amorphous structure of Ni P, but made the cellular microstructure of Ni P BN w electroless composite coating refined obviously, as a result, the crystallization temperature of the coating was lowered, and the microhardness and wear resistance was increased obviously.
