Embodiment 1

[0034] The specific preparation method is:

[0035] ①Using the synchronous sintering blackening method, the zirconia ceramic powder is processed into a workpiece blank, and the formed white zirconia workpiece blank is placed in graphite powder, and then placed in a vacuum furnace and heated to 1350°C for 2 hours A black zirconia ceramic is obtained. Based on the total weight of the ceramic part, the carbon content is 2wt%;

[0036] ②Put the treated zirconia ceramics in a container filled with water, and then place them in an ultrasonic environment for 20 minutes to remove the dirt on the surface of the black zirconia ceramics;

[0037] ③ After cleaning, put the blackened zirconia ceramic workpiece, nickel-based alloy (Ni 90wt%, P 10wt%), the front end and the rear end of the stainless steel back cover into a connecting mold, so that the nickel-based alloy is clamped between the front end of the back cover and the back end. Between the blackened zirconia ceramics, between the...

Embodiment 2

[0042] The specific preparation method is:

[0043] ①Using the simultaneous sintering blackening method, 85vol% zirconia ceramic powder and 15vol% yttrium oxide are processed into workpiece blanks, and the formed white composite zirconia workpiece blanks are placed in graphite powder, and then placed in a vacuum furnace Heating to 1550°C and holding the temperature for 2 hours to obtain black composite zirconia ceramics. Based on the total weight of the ceramic part, the carbon content is 2wt%;

[0044] ②Put the treated zirconia ceramics in a container filled with water, and then place them in an ultrasonic environment for 10 minutes to remove the dirt on the surface of the black zirconia ceramics;

[0045] ③ After cleaning, put the blackened zirconia ceramic workpiece, nickel-based alloy (Ni 88wt%, P 12wt%), the front end and rear end of the stainless steel back cover into a connecting mold, so that the nickel-based alloy is clamped between the front end of the back cover an...

Embodiment 3

[0050] The specific preparation method is:

[0051] ①Using synchronous sintering blackening method, 90vol% zirconia ceramic powder and 10vol% magnesia powder are processed into a workpiece blank, and the formed white zirconia workpiece blank is placed in graphite powder, and then placed in a vacuum furnace Heating to 1450°C and holding the temperature for 4 hours to obtain black zirconia ceramics. Based on the total weight of the ceramic part, the carbon content is 4wt%;

[0052]②Put the treated zirconia ceramics in a container filled with water, and then place them in an ultrasonic environment for 15 minutes to remove the dirt on the surface of the black zirconia ceramics;

[0053] ③ After cleaning, put the blackened zirconia ceramic workpiece, nickel-based alloy (Ni 80wt%, P 10wt%, Cu10%), the front end and rear end of the copper back cover into a connecting mold, so that the nickel-based alloy is clamped on the back Between the front end of the cover and the blackened zir...

Abstract

The invention provides a connecting piece between zirconia ceramics and metal and a connecting method thereof. The connecting piece includes a ceramic piece, a metal piece, and a connecting piece connecting the ceramic piece and the metal piece; the ceramic piece is carburized and blackened A zirconia ceramic part or a carburized and blackened composite zirconia ceramic part; the melting point of the metal part is higher than 1000°C; the connecting part is a nickel-based alloy part. The connection between zirconia ceramics and metals of the present invention uses cheap nickel-based alloys as solder to connect metals and ceramics to meet the welding requirements, but this solution has great advantages in cost and convenience.

Description

technical field [0001] The invention belongs to the field of connection between metal and ceramics, and in particular relates to a connecting piece of zirconia-based ceramics and technology and a connecting method thereof. Background technique [0002] In the connection technology of ceramics and metals, the active metal welding method is the most widely used. This method must ensure that the active solder has good wettability and bonding properties for the connected ceramics and metals. At present, Ag-Cu-Ti alloy solder with Ti as the active component and Ag-Cu eutectic as the matrix is ​​widely used to directly bond the metal to the ceramic; The surface is metallized, and then the plated metal is joined to the metal to be welded using brazing filler metals. [0003] Ag-Cu-Ti alloy solder contains more precious metals, so the cost is relatively high, the product is expensive, and its application is limited to a certain extent; while the Mo-Mn surface metallization method i...
