Abstract

The present disclosure provides a metal-ceramic composite structure and a fabrication method thereof. The metal-ceramic composite structure includes a ceramic substrate having a groove on a surface thereof; a metal member filled in the groove, including a main body made of zirconium base alloy, and a reinforcing material dispersed in the main body and selected from at least one of W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC, ZrO2, BN, Si3N4, TiN and Al2O3; a luminance value L of the metal member surface is in a range of 36.92-44.07 under a LAB Chroma system.

First claim

The invention claimed is:

1. A metal-ceramic composite structure, comprising:
a ceramic substrate, having a groove on a surface of the ceramic substrate; and
a metal member, filled in the groove and comprising:
a main body, made of zirconium base alloy;
a reinforcing material, dispersed in the main body, and selected from at least one of W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC, ZrO 2 , BN, Si 3 N 4 , TiN and Al 2 O 3 , and the selected reinforcing material including a carbon element,
wherein the reinforcing material and the zirconium base alloy are mixed such that the reinforcing material is dispersed evenly in the zirconium base alloy; a ratio of a volume of the reinforcing material to a total volume of the reinforcing material and the zirconium base alloy is in a predetermined range of 5%-30%, so as to avoid pores formed in the metal member to achieve a desired appearance quality; and the carbon element in the reinforcing material reacts with Zr element in the zirconium base alloy to form a ZrC, so as to improve a bonding force between the zirconium base alloy and the reinforcing material, and a hardness of the metal member is between 600 to 680 Hv.

2. The metal-ceramic composite structure according to claim 1 , wherein the reinforcing material has particle shape, and a D50 particle size of the reinforcing material is in a range of 0.1 μm-100 μm.

3. The metal-ceramic composite structure according to claim 1 , wherein the zirconium base alloy is a zirconium base amorphous alloy.

4. The metal-ceramic composite structure according to claim 3 , wherein the ceramic substrate is a zirconia ceramic.

5. The metal-ceramic composite structure according to claim 1 , wherein a depth of the groove is at least 0.1 mm.
