Problems solved by technology

[0009] The two methods disclosed in Document 2 and Document 3 form the metal connection layer through high temperature and low pressure, and both have the problem that the thickness of the metal layer is difficult to control and uneven. At the same time, the metal is unevenly distributed during the solidification process, and many dendrites and twin Crystal and other crystal defects, resulting in poor mechanical properties of the connector

Embodiment 1

[0032] A carbon / carbon composite material and metal material composite cooking utensil production method, it comprises the following steps:

[0033] (1) Carbon / carbon composite material outer layer green body preparation: the carbon / carbon composite material green body is machined into the carbon / carbon composite material outer layer green body 2 of the desired shape, washed and dried for later use;

[0034] The carbon / carbon composite body in the present invention can be prepared by one or a combination of molding, chemical vapor deposition or liquid phase impregnation methods. In this embodiment, the carbon fiber is made into a prefabricated carbon fiber base layer according to the required structure and shape, and then densified by chemical vapor deposition.

[0035] In order to remove impurities in the outer body 2 of the carbon / carbon composite material, the present invention puts the prepared outer body 2 of the carbon / carbon composite material into a high-temperature fu...

Embodiment 2

[0057] In step (2) of the present invention, the metal salts are aluminum nitrate and chromium nitrate, the atomic number ratio of aluminum ions to chromium ions in the aqueous alcohol solution is 15:4, and aluminum nitrate and nitric acid are prepared on the surface of the outer body 2 of the carbon / carbon composite material Chrome coating. In step (3), a carbon / carbon composite outer layer green body 2 with a metal particle layer of aluminum particles and chromium particles on the surface is prepared, and the thickness of the metal particle layer is 28 μm. In step (4), the metal material inner layer green body 3 is made of metal aluminum material.

[0058] After testing, the shear strength of the interface between the base body 2 of the carbon / carbon composite material and the base body of the metal aluminum material in this embodiment is 30 MPa.

[0059] The rest are the same as embodiment 1.

Embodiment 3

[0061] In step (2) of the present invention, the metal salts are nickel nitrate and copper sulfate, the atomic number ratio of nickel ions to copper ions in the aqueous alcohol solution is 15:2, and nickel nitrate and sulfuric acid are prepared on the surface of the outer body 2 of the carbon / carbon composite material copper coating. In step (3), put the carbon / carbon composite outer layer body 2 prepared in step (2) into a reduction furnace, and pass through hydrogen at 1100°C for calcination and reduction. The reduction time is 3 hours, and then cooled to room temperature to produce A carbon / carbon composite material outer layer green body 2 having a metal particle layer with nickel particles and copper particles on the surface is obtained; the thickness of the metal particle layer is 50 μm. In step (4), the metal material inner layer green body 3 is made of metal iron material. In step (5), the carbon / carbon composite material outer layer body 2 obtained in step (3) and th...

Abstract

The invention discloses a carbon / carbon composite and metallic material compound cooker and a production method. The method is characterized by comprising the steps of carbon / carbon composite material outer layer green body manufacture, liquid phase impregnation, calcination reduction, metal material inner layer green body manufacture and composite treatment. The manufactured compound cooker comprises a carbon / carbon composite material outer layer green body, a metal material inner layer green body, and a connecting layer connecting the carbon / carbon composite material outer layer green body and the metal material inner layer green body. The method is simple in technology. The metal connecting layer is prepared on the surface of the carbon / carbon composite through the liquid phase impregnation and the calcination reduction, and the chemical component and the micro-geometry structure of the surface of the carbon / carbon composite are changed. Moreover, the attached metal connecting layer and the metal materials have good compatibility, so that the produced carbon / carbon composite and metallic material compound cooker has the advantages of being quick in heating, high in heat efficiency, light, corrosion resistant, high in strength and the like compared with an existing single-iron electromagnetic heating cooker or other existing multi-metal electromagnetic heating cookers.

Description

technical field [0001] The invention relates to a heating cooker, in particular to a carbon / carbon composite material and metal material composite cooker and a production method thereof. Background technique [0002] The induction cooker is the product of the modern kitchen revolution. It does not need an open flame or conduction heating, but allows heat to be generated directly at the bottom of the pot, so the thermal efficiency has been greatly improved. It is a kind of high-efficiency and energy-saving kitchen utensils, which is completely different from all traditional conduction heating with or without fire. Since the induction cooker generates heat by directly inducing a magnetic field at the bottom of the pot to generate eddy currents, traditional cookers for induction cookers are made of cast iron or stainless steel. Due to the high density of iron (about 7.81g / cm 3 ), and the heat preservation performance is poor, and the iron cookware is heavy, which is not conduc...
