摘要：

In the present paper, micro-grooved Ti3SiC2 surfaces with different roughness were fabricated by pulsed laser processing. The surface topography and chemical composition of smooth and micro grooved surfaces were characterised. The wetting behaviours of smooth and micro-grooved Ti3SiC2 surfaces such as static contact angle, anisotropic wettability and contact angle evolution versus time were investigated. The experimental results show that micro grooved structures can be efficiently fabricated on Ti3SiC2 surface by laser processing. The contact angle of micro grooved surface was increased by 64.2 degrees compared with that of smooth surface. The difference values of contact angles between perpendicular and parallel direction were <10 degrees. The wetting state of droplet on textured surface was close to Cassie-Baxter model.
