Abstract

A MAX-phase material is provided for a cutting tool and other applications.

Claims

1. A cutting tool, comprising:

a support substrate; and

a complex ceramic cutting surface laminate formed on the support substrate and including hard shards, a first row transition-metal element, an element from columns III-VI of the periodic table and carbon and/or nitrogen,

wherein the laminate includes a MAX-phase material having atomic-scale chemical uniformity uprising M_(n+1)AX_n (MAX) phase material;

where M is the first row transition-metal element, where A is the element from columns III-VI of the periodic table and where X is the carbon and/or nitrogen,

wherein the MAX-phase material is a crystalline structure with uniformly mixed X-group nanoparticles as an excess secondary phase material formed using a super stoichiometry of X-group precursor materials.

2. The tool of claim 1, wherein the MAX-phase material has micro-Vickers hardness greater than 1 GPa.

3. The tool of claim 2, wherein the MAX-phase material has micro-Vickers hardness greater than 4 GPa.

4. The tool of claim 1, wherein the MAX-phase material further includes particles embedded within it that include carbon fiber, coated-carbon fiber, and/or aluminum nitride particles.

5. The tool of claim 1, wherein the hard shards comprise diamond.

6. The tool of claim 1, wherein the substrate is a drill bit.

7. The tool of claim 1, wherein the laminate is formed on the substrate by liquid chemical deposition of a colloidal solution of nanoparticles in dissolved metal-organic precursors.
