Fabrication and characterization of micro-dimple array on Al2O3 surfaces by using a micro-tooling

Tribological performance of the biological components of synovial fluid in artificial joint implants

“…It restores patient mobility and enables a comfortable and independent life [1, 2]. Despite its high success rate, recent data shows that the revision rate is still unexpectedly high; for example, the National Joint Registry of England and Wales reported that overall, 11 and 12% of all total hip replacements failed in 2011 and 2012, respectively [3]. Interestingly, there are a number of research and development (R&D) companies working towards long-lasting artificial joints along with major research universities around the world.…”

Sandwich-like electrochemical micromachining of micro-dimples

“…All these parameters have been found to affect tribological performance. Therefore, the machining accuracy of surface texturing is a key factor for a high-quality textured surface [12]. Rathod et al [13] investigated the influence of machining parameters on the machining accuracy of microgrooves fabricated by EMM using a reverse-tapered microtool, and their experiments verified that lower applied voltage, lower duty ratio, and higher pulse frequency are recommended for improving machining accuracy.…”

Micro-dimple array fabricated on surface of Ti6Al4V with a masked laser ablation method in air and water

“…In general, the present manufacturing approaches of micro-dimples can be classified into mechanical methods [6,7], etching technologies [8,9] and laser based methods [10][11][12][13]. Compared with the other two methods, laser based methods have unique advantages such as absence of tool wear, friendly environment, ease of operation, and the ability to produce micro-dimples in a wide variety of material.…”
