Abstract

The invention discloses a titanium-silicon-carbon ceramic structure with a hydrophobic microstructure. The titanium-silicon-carbon ceramic structure comprises a titanium-silicon-carbon ceramic workpiece, a working face of the titanium-silicon-carbon ceramic workpiece is uniformly provided with a micro-groove array structure composed of a plurality of longitudinal micro-groove structures parallel with a length direction of the working face, the depth of the longitudinal micro-groove structures is 50-200 microns, and the distance between every two adjacent micro-groove structures is 60-1000 microns. The invention further discloses a preparation method of the titanium-silicon-carbon ceramic structure with the hydrophobic microstructure. The method and structure has the effects that 1, fine electric spark discharge machining is carried out, and the micro-groove structures with high quality and regular shape can be processed, and have relatively high shape precision; 2, the preparation method can be used for allowing the surface of titanium-silicon-carbon ceramic structure to be machined the micro-groove structures, the micro-scale can be controlled to hundred microns or even several microns, and shape features can also be controlled; and 3, compared with a traditional ceramic workpiece, the ceramic workpiece with the microstructure array has a good hydrophobic function.

Description

technical field [0001] The invention relates to the field of precision and micro-manufacturing, in particular to a titanium-silicon-carbon ceramic structure with a hydrophobic microstructure and a preparation method thereof. Background technique [0002] Titanium silicon carbide (Ti 3 SiC 2 ) Ceramics, which have the characteristics of high melting point, high chemical stability and high wear resistance of ceramics, and it also has the electrical conductivity, thermal conductivity, high toughness, high temperature plasticity and good machinability of metals. It is a "soft" ceramic with metallic properties and has broad application prospects. [0003] In chemistry, hydrophobicity refers to the physical property of a molecule and water to repel each other. Property Theory According to the theory of thermodynamics, matter will seek to exist in the lowest energy state, and hydrogen bonding is a way to reduce chemical energy. Water is a polar substance and can therefore form ...
