Methods of making and using cubic boron nitride composition, coating and articles made therefrom

A method of shaping a workpiece, comprising contacting the workpiece with a tool work surface, wherein the work surface comprises a substrate having a continuous composite layer formed thereon, wherein said composite layer is formed by depositing solid particles on the substrate to form a base layer, and infiltrating said base layer with a gas, wherein said particles comprise at least one of the group consisting of nitrides, carbides, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides, wherein said solid particles are deposited as a dry phase, wherein said continuous composite layer comprises at least one of the group consisting of nitrides, carbides, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides, wherein said gas is in contact with particles of the base layer, and wherein said gas is in contact with portions of the substrate at regions between particles of the base layer.

A method of coating a substrate comprising:

• (A) depositing solid particles on the substrate to form a base layer, wherein said particles are in contact with the substrate, and wherein said particles comprise at least one of the group consisting of nitrides, carbides, carbonitrides, borides, oxides, sulphides, and silicides;
• wherein said solid particles are deposited as a dry phase, and
• (B) infiltrating said base layer with a gas to form a continuous composite layer on the substrate, wherein said continuous composite layer comprises at least one of the group consisting of nitrides, carbides, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides.
