Surface texturing can be defined as a technique that consists of creating micro cavities in the surface of a material. There are different texturing techniques such as chemical etching, electromechanical micromachining, diamond embossing, electric discharge, pellet-pressing and laser surface, the last being the most common. For years, these surface texturing techniques have been used in tribological applications because microcavities can store oils or fluids and constantly lubricate the surfaces that are subjected to wear; they can also be used to trap wear particles (debris) that would otherwise act as abrasive particles (three body abrasive wear). This literature review seeks to analyse and compare the advantages that the use of surface texturing techniques can offer in reducing the wear of prosthetic components and therefore lengthening their useful life, to provide a better quality of life to patients. The results of this review showed a growing interest in the scientific community in the use of surface texturing for biotribogical applications, using to a greater extent the Laser Surface Texturing (LST) technique and the surface pattern composed by dimples.

This investigation shows a solution to improve the problem of premature wear in the screw ball elements of CNC turning lathe. Screw ball element is an essential component for the movement of a lathe operated by computerized numerical control (CNC). Four ball tribotester T-02 was used to find the best anti wear properties on lubricants with Halloysite Nanotubes (HNTs) then, through the use of laser surface texturing (LST) micro cavities with 15 µm of depth were added to the surface of the screw and with the addition of Halloysite Nanotubes (HNTs) in the base lubricant; tribological performance was upgraded. Important achievements were reached: 38 % of increment in wear resistance and reduction in surface finished roughness (Ra) up to 11 % in the CNC machine element (screw ball).
