Problems solved by technology

It is difficult to form a stepwise change in thermal expansion coefficient with a single metal layer, which has limited effect on reducing thermal stress, and the bonding force is not good
However, the multi-layer metal layers currently used pay more attention to the activity of the middle metal layer and the interaction between them, and fail to fully consider the stepwise transformation of the thermal expansion coefficient, which cannot greatly reduce the thermal stress.

Embodiment Construction

[0033] figure 1 Shown is the brass and silicon carbide ceramic composite part 10 produced by the above manufacturing method, including the silicon carbide ceramic part 20, the brass part 30 and the connecting layer connecting the brass part 30 and the silicon carbide ceramic part 20 80. The connecting layer 80 includes a first transition layer 81 , an aluminum layer 82 , a second transition layer 83 , a nickel layer 84 and a third transition layer 85 . The first transition layer 81 is located between the silicon carbide ceramic part 20 and the aluminum layer 82 . The first transition layer 81 is mainly composed of aluminum carbide and silicon aluminum compounds, such as aluminum carbide. The second transition layer 83 is located between the aluminum layer 82 and the nickel layer 84 , which is a transition layer connecting the aluminum layer 82 and the nickel layer 84 . The second transition layer 83 is mainly composed of Al-Ni compound and Al-Ni solid solution. The third t...

Abstract

The invention provides a manufacturing method of brass and silicon carbide ceramics, mainly comprising the steps of adopting aluminium foil and nickel foil as a connecting medium layer in a hot-press sintering furnace and realizing the solid-phase diffusion connection of the brass and the silicon carbide ceramics. The invention also provides a brass and silicon carbide ceramic composite piece obtained by utilizing the manufacturing method. The brass and silicon carbide connected through the manufacturing method have high binding force.

Description

technical field [0001] The invention relates to a metal and ceramic composite part and a manufacturing method thereof, in particular to a brass and silicon carbide ceramic composite part and a manufacturing method thereof. Background technique [0002] Brass has good corrosion resistance at room temperature and is widely used in the manufacture of various engineering structures and mechanical parts. However, in relatively harsh environments such as high temperature and corrosiveness, the corrosion resistance, wear resistance, erosion resistance, and high temperature resistance of brass have been difficult to meet the further needs of modern production technology. Silicon carbide ceramics have the advantages of high hardness, high temperature corrosion resistance, wear resistance, and erosion resistance. Therefore, brass and silicon carbide ceramics are connected together to form a composite structure, which is of great significance for the application of brass in harsh envi...
