Problems solved by technology

[0002] The Achilles heel of ceramic materials is brittleness. Under the action of external force, stress concentration occurs on the surface of the material or at the tip of micro-cracks in the interior, and the crack expands to form surface energy to consume energy. Therefore, the crack propagation speed is extremely fast, often causing the ceramic material to suffer in an instant. to catastrophic damage

Description

technical field [0001] The invention relates to the field of materials, in particular to a titanium dioxide-added modified composite ceramic material and a preparation method thereof. Background technique [0002] The Achilles heel of ceramic materials is brittleness. Under the action of external force, stress concentration occurs on the surface of the material or at the tip of micro-cracks in the interior, and the crack expands to form surface energy to consume energy. Therefore, the crack propagation speed is extremely fast, often causing the ceramic material to suffer in an instant. to catastrophic damage. Titanium dioxide has outstanding light and heat resistance effects, good chemical corrosion resistance, good wettability with the substrate, and less interface reaction, which can improve the mechanical properties, wear resistance, and hardness of composite materials, reduce thermal expansion coefficient, and the cost is relatively low. lower. Therefore, the present i...
