Abstract
A composite material includes: coated particles, each of which includes a carbon-based particle made of a carbon-based substance and a carbide layer that covers at least a part of the surface of the carbon-based particle; and a copper phase that binds the coated particles to each other, wherein the carbide layer is made of a carbide containing at least one element selected from the group consisting of Si, Ti, Zr and Hf, and the average particle size of the carbon-based particles is 1 μm or more and 100 μm or less.
Claims12
A composite material comprising:
- coated particles, each of which includes a carbon-based particle made of a carbon-based substance and a carbide layer that covers at least a part of the surface of the carbon-based particle;
- and
- a copper phase that binds the coated particles to each other,
- the carbide layer being made of a carbide containing at least one element selected from the group consisting of Si, Ti, Zr and Hf, and
- the average particle size of the carbon-based particles being 1 μm or more and 100 μm or less.
A composite material manufacturing method comprising:
- a step of forming a laminated body by laminating a first layer and a second layer;
- and
- a step of heating the laminated body,
- the first layer including:
- a first powder made of a carbon-based substance;
- and
- a second powder made of at least one of a compound containing at least one element selected from the group consisting of Si, Ti, Zr and Hf, and the element itself,
- the second layer including:
- a copper material consisting of Cu and inevitable impurities;
- and
- the second powder,
- in the heating step, the copper material being heated to a molten state under a vacuum atmosphere of 1 Pa or less, a reducing atmosphere or an inert atmosphere without pressurization, and compounded with the first powder.
