Abstract

Disclosed is a method for preparing a carbon-reinforced metal-ceramic composite material, including: mixing raw materials of carbon, copper, zinc, titanium, copper oxide, calcium oxide and titanium dioxide, ball-milling the raw materials with a medium of ethanol to obtain a mixture, drying and milling the mixture to obtain a powder, sintering the powder with a laser having an irradiation power ranging from 100 to 600 W and an irradiation period of 3 min to 10 min to obtain a product, and rapidly cooling the product to allow a temperature of the product to be decreased to the room temperature within 5 min to obtain the carbon-reinforced metal-ceramic composite material.

First claim

What is claimed is:

1. A method for preparing a carbon-reinforced metal-ceramic composite material, comprising:
mixing raw materials of carbon at 5 wt % to 8 wt %, copper at 10 wt % to 15 wt %, zinc at 10 wt % to 18 wt %, titanium at 20 wt % to 33 wt %, copper oxide at 5 wt % to 8 wt %, calcium oxide at 18 wt % and 35 wt % and titanium dioxide at a balance amount to 100 wt %, based on a total amount of the raw materials,
ball-milling the raw materials with a medium of ethanol to obtain a mixture,
drying and milling the mixture to obtain a powder,
sintering the powder with a laser having an irradiation power ranging from 100 to 600 W and an irradiation period of 3 min to 10 min to obtain a product, and
rapidly cooling the product to allow a temperature of the product to be decreased to room temperature within 5 min to obtain the carbon-reinforced metal-ceramic composite material.

2. The method according to claim 1 , wherein the ball-milling is performed at a ball-milling speed of 400 rpm for a period ranging from 8 to 24 h.

3. The method according to claim 1 , wherein the drying is performed at a temperature in a range of 60 to 80° C.

4. The method according to claim 1 , wherein the milling includes at least one of manual grinding and ball-milling.

5. The method according to claim 1 , wherein the carbon is provided by a carbon source selected from at least one of sucrose, glucose, a carbon-containing organic solvent, a graphite powder, a carbon nanomaterial, and graphene.

6. The method according to claim 1 , wherein the laser is a semiconductor laser having a laser wavelength of 980 nm.

7. The method according to claim 1 , wherein the laser is a CO 2 laser having a laser wavelength of 1060 nm.

8. The method according to claim 1 , wherein rapidly cooling the product comprises:
spraying liquid nitrogen or liquid ammonia onto the product.
