AB Machining titanium alloys, particularly Ti6Al4V, pose significant challenges inmanufacturing engineering. The combination of high strength and low thermal conductivitymakes Ti6Al4V a particularly difficult material to machine. One of these difficulties is therapid wear and short tool life of cutting tools, which substantially increases manufacturingcosts. To address this issue, the texturing of cutting tools, especially using laser-basedtechniques, has garnered significant attention due to its potential to enhance the tribologicalperformance of textured surfaces. In this paper, by means of a groove design applied to atungsten carbide (WC) disc by laser surface texturing (LST), its behavior and wear havebeen evaluated after subjecting it to tribological pin-on-flat tests by confronting it withTi6Al4V pins with different reciprocating times (250 s, 500 s, 750 s and 1000 s) in lubricatedand dry conditions. In addition, these same tests have been replicated without texturesfor comparison. Through conducting this research, we expect to gain new insights intotexturing processes and their influence on friction and sliding behavior under lubricatedconditions. Additionally, the study aims to evaluate how lubricant retention capacity variesto reduce friction and wear across different testing durations. The results show betterbehavior with textures, reaching a higher rate of volume loss in the titanium pins. The mainconclusions obtained after these tests are that textures offer a better performance in tests upto 800 s. In addition, after this time, the lubricant begins to lose its properties, becoming anabrasive paste.
