Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0015] This case proposes an embodiment of high-strength wear-resistant ceramic powder, including the following materials by weight:

[0016]

[0017] As another embodiment of the present application, 2-4 parts by weight of boron phosphide are further included. Boron phosphide can synergistically improve the strength of ceramics, but it should be noted that the amount of boron phosphide added should be limited. If the amount of boron phosphide added is less than 2 parts by weight, the synergistic effect cannot be activated and the ceramic cannot be effectively improved. strength and toughness; if the addition of boron phosphide is greater than 4 parts by weight, boron phosphide will inhibit the effect of uranium nitride and lanthanum boride in ceramics, and during calcination, part ...

Abstract

The invention discloses high-strength wear-resistant ceramic powder which is prepared from the following components in parts by weight: 50-52 parts of zirconium oxide, 20-22 parts of aluminum oxide, 14-16 parts of boron oxide, 10-12 parts of titanium oxide, 6-8 parts of beryllium oxide, 2-4 parts of uranium nitride and 2-4 parts of lanthanum boride. According to the scheme, the ceramic powder is improved and optimized, multiple metal oxides, carbides and phosphides with a synergistic effect are introduced, and the strength and the wear resistance of the ceramic are effectively enhanced; by adding animal bone ash powder into the powder, the mechanical strength and the structural toughness of the ceramic are improved; by adding the nanoscale strontium carbonate into the powder, when the ceramic powder is calcined, multiple tiny cavities are formed in the ceramic by the tiny carbon dioxide gases obtained by decomposing the strontium carbonate; the cavities are combined to form a honeycomb-like structure or a microporous structure, and the strength, the wear resistance and the toughness of the ceramic are further improved.

Description

technical field [0001] The invention relates to a ceramic powder composition, in particular to a high-strength wear-resistant ceramic powder. Background technique [0002] High-strength ceramics play an important role in modern industry, and they have many applications in aerospace, machinery, electronics, semiconductors and precision machining. However, due to the congenital defects of ceramics such as brittleness, the application of ceramics was once limited, but with the urgent needs of industrial applications, people are constantly developing higher strength, better impact resistance and better wear resistance. ceramic material. In the prior art, the formula composition of ceramic powder has a significant impact on the performance of ceramics after calcination. Even a small amount of addition or change will change the performance of the molded ceramics, such as strength, impact resistance, oxidation resistance, and high temperature resistance. , corrosion resistance an...
