Abstract
A method of forming an activated coating composition is disclosed. The method includes providing (a) boron nitride, (b) carbon, (c) aluminum oxide and (d) a liquid carrier. Each of the boron nitride, carbon and aluminum oxide are in particulate form. The coating composition is activated to form an activated coating composition. The activated coating composition includes active components having from about 60.0 wt % to about 90.0 wt % boron nitride, from about 16 wt % to about 24 wt % carbon and from about 4 wt % to about 6 wt % aluminum oxide. A coating method, coated substrate and activated coating composition are also disclosed.
Claims21
A method of forming a coating composition, comprising:
- providing (a) boron nitride, (b) carbon, (c) aluminum oxide and (d) a liquid carrier, each of the boron nitride, carbon and aluminum oxide being in particulate form;
- and
- activating the coating composition to form an activated coating composition;
- wherein the activated coating composition includes active components (a), (b) and (c) having from about 60.0 wt % to about 90.0 wt % boron nitride, from about 16 wt % to about 24 wt % carbon and from about 4 wt % to about 6 wt % aluminum oxide and the boron nitride includes hexagonal boron nitride.
A method of coating a substrate, comprising:
- providing an activated coating composition (a) boron nitride, (b) carbon and (c) aluminum oxide in (d) a liquid carrier;
- and
- contacting a substrate surface with the activated coating composition to form a coated substrate;
- wherein the activated coating composition includes active components (a), (b) and (c) having from about 60.0 wt % to about 90.0 wt % boron nitride, from about 16 wt % to about 24 wt % carbon and from about 4 wt % to about 6 wt % aluminum oxide and the boron nitride includes hexagonal boron nitride.
An activated coating composition comprising (a) boron nitride, (b) carbon, (c) aluminum oxide and (d) a liquid carrier, wherein the activate composition has been activated with mechanical energy;
- wherein the activated coating composition includes active components having from about 60.0 wt % to about 90.0 wt % boron nitride, from about 16 wt % to about 24 wt % carbon and from about 4 wt % to about 6 wt % aluminum oxide and the boron nitride includes hexagonal boron.
