Abstract
A composite article includes a first composite material and a second composite material. The first composite material and the second composite material individually comprise hard particles in a binder. A concentration of ruthenium in the binder of the first composite material is different from a concentration of ruthenium in the binder of the second composite material.
Claims24
A composite cutting tool for machining of metals and metallic alloys, comprising:
- a first region comprising a first composite material;
- and
- a second region metallurgically bonded to the first region and comprising a second composite material,
- wherein the first composite material and the second composite material individually comprise hard particles and a binder, wherein the binder of at least one of the first composite material and the second composite material comprises ruthenium, and wherein a concentration of ruthenium in the binder of the first composite material is different from a concentration of ruthenium in the binder of the second composite material.
A composite cutting tool insert for machining of metals and metallic alloys selected from the group consisting of indexable turning inserts, indexable milling inserts, and indexable drilling inserts, the cutting tool insert comprising:
- a first region consisting of a first cemented carbide composite material and including a cutting edge;
- and
- a second region metallurgically bonded to the first region and consisting of a second cemented carbide composite material,
- wherein the first cemented carbide composite material and the second cemented carbide composite material individually comprise carbide particles in a binder, wherein the binder of the first cemented carbide composite material comprises 5 weight percent to 30 weight percent ruthenium, and wherein the binder of the second cemented carbide composite material either lacks ruthenium or comprises an incidental amount of ruthenium.
A composite cutting tool insert for machining of metals and metallic alloys selected from the group consisting of end mill inserts and spade drill inserts, the cutting tool insert comprising:
- a first region consisting of a first cemented carbide composite material and including a cutting edge;
- and
- a second region metallurgically bonded to the first region and consisting of a second cemented carbide composite material,
- wherein the first cemented carbide composite material and the second cemented carbide composite material individually comprise carbide particles in a binder, wherein the binder of the first cemented carbide composite material comprises 5 weight percent to 30 weight percent ruthenium, and wherein the binder of the second cemented carbide composite material either lacks ruthenium or comprises an incidental amount of ruthenium.
