preparation example Construction

[0019] The present invention also provides a method for preparing a metal-ceramic composite product, the steps of which include:

[0020] S1, filling A material in the groove of the ceramic substrate with pattern grooves on the surface, and then sintering at 1000°C-1200°C in a protective atmosphere to form a reinforced phase skeleton in the groove, wherein A is selected from W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC or ZrO 2 one or more of them. Generally the filler material particles, preferably, the particle size of the particles is 0.1-100 μm. Filling the A material can be done by a common filling method. Preferably, in the present invention, the A material is dissolved in a solvent to form a slurry, and the slurry is filled in the groove. The function and type of the organic solvent are well known to those skilled in the art. . The slurry can also contain modified additives such as powder surfactants. For example, silane coupling agent 9116 is added to the slurr...

Embodiment 1

[0029] (1) Weigh 300g of W powder (particle size D50 is 1μm) and 1.2g of silane coupling agent 9116, dissolve in 25g of methyl silicone oil, stir the two for about 2h and mix them evenly, defoaming in a vacuum drying box for 30min, to obtain W-containing slurry, coat the W-containing slurry on the surface grooves of the zirconia ceramics with a depth of 0.20mm and a width of 0.5mm formed during the preforming of the green body, fill the grooves, and place them in a vacuum drying oven again. The zirconia ceramics were degassed for 30min, then the zirconia ceramics were sintered in a vacuum resistance furnace, heated to 600℃ at 2℃ / min, kept at 600℃ for 1h, then heated to 1100℃ at 10℃ / min and kept for 1h to form a reinforced The porosity of the reinforced phase skeleton was measured to be 62.8% by the drainage method.

Abstract

A metal-ceramic composite includes a ceramic substrate and a metallic composite. A groove is formed in a surface of the ceramic substrate and the metallic composite is filled in the groove. The metallic composite includes a Zr based alloy-A composite. A includes at least one selected from a group consisting of W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC and ZrO2. Based on the total volume of the Zr based alloy-A composite, the content of A is about30％to about70％by volume.A method for preparing the metal-ceramic composite is also provided.

Description

technical field [0001] The invention belongs to the field of ceramic-metal composite materials, in particular to a metal-ceramic composite product and a preparation method thereof. Background technique [0002] Metal-ceramic composite wear-resistant materials are mainly used in metallurgy, building materials, mining, refractory materials and electric power and other fields of material crushing and wear-resistant parts in grinding equipment, such as roller sleeves, lining plates, grinding rings, grinding discs, etc. Developed for high wear resistance requirements, the performance of metal-ceramic composites depends on the performance of metal, ceramic performance and the bonding strength of the two. The excellent properties of metal-ceramic composites make them widely used in many fields. For example, existing research is also used to prepare metal decorative ceramic products with both ceramic or overall mirror effect and metal matte effect, which have good wear resistance a...
