Nibron is Purecoat International LLC's registered trade name for an electroless nickel-thallium-boron coating.

It is an engineered surface deposit coating which is readily applied to a variety of substrate, such as steel and nickel alloys, aluminum, cobalt alloys, copper alloys, and titanium, to provide fretting and galling and has nearly three times wear resistance of medium phos. electroless nickel and twice the wear resistance of low phos. electroless nickel. It's application process minimizes any potential for hydrogen embrittlement.

Nibron's unique "columnar" structure results in a more ductile deposit-permitting the substrate to flex in application without loss of adhesion.

Nibron is applied to titanium Inlet Guide Vanes, critical to military turbine engine efficiency, to minimize wear on the vane stem journals and contact face.
