“…There are different texturing techniques such as sandblasting, ion beam texturing, etching technique, machining, and laser texturing, being the last one the most innovative in recent years [8,9]. Surface texturing has been used successfully in tribological applications where it is sought to reduce wear between sliding surfaces, since there is evidence that the cavities that are created with this technique can be used to store lubricant (Figure 1(a)) and keep the sliding surfaces constantly lubricated; furthermore, the cavities can also be used to trap wear particles (debris) that would otherwise produce third-body abrasive wear [9][10][11][12], as can be seen in Figure 1 In some cases, the benefits of texturing have been used for biotribological applications with the aim of reducing wear between components of joint prostheses, where positive results have been obtained; an example of this is the work of Ito et al, where concave dimples (diameter of 0.5 mm, pitch of 1.2 mm, and depth of 0.1mm) were textured on the surface of a Co-Cr alloy femoral head using the electrical discharge etching technique. Wear tests were carried out using a hip joint simulator with a metal-on-polyethylene configuration, the results showed that dimples reduced COF and wear by 35% and 68%, respectively [13].…”
