“…In 2013, Chauhan et al [87] used the response surface methodology to study the dry sliding wear behavior of titanium alloys. Sahoo et al [88] studied the effect of microstructure on the dry sliding wear behavior of titanium alloys. In 2015, Sharma et al [89] studied the tribological behavior of Ti-3Al-2.5V alloy sliding against EN32 steel disc of hardness 62HRC, in the dry sliding condition.…”

The need for metallic biomaterials will always remain high with their growing demand in joint replacement in the aging population. This creates need for the market and researchers to focus on the development and advancement of the biometals. Desirable characteristics such as excellent biocompatibility, high strength, comparable elastic modulus with bones, good corrosion resistance, and high wear resistance are the significant issues to address for medical implants, particularly load-bearing orthopedic implants. The widespread use of titanium alloys in biomedical implants create a big demand to identify and assess the behavior and performance of these alloys when used in the human body. Being the most commonly used metal alloy in the fabrication of medical implants, mainly because of its good biocompatibility and corrosion resistance together with its high strength to weight ratio, the tribological behavior of these alloys have always been an important subject for study. Titanium alloys with improved wear resistance will of course enhance the longevity of implants in the body. In this paper, tribological performance of titanium alloys (medical grades) is reviewed. Various methods of surface modifications employed for titanium alloys are also discussed in the context of wear behavior.

“…ANOVA, a statistical model, based on the least square method, is useful for developing and confirming the experimental values. Taguchi's technique was used to examine the importance of each process parameter on the performance features of an alloy or composites [35,36]. Palanisamy et al [37] investigated the wear behavior of Al-fly ash composites by the Taguchi approach.…”

A356 Aluminium Alloy-Zircon composites were synthesized through the stir casting technique by introducing different volume fractions of zircon particles (3, 6, and 9 %). Stir casting process was carried out at the stirring speed of 600 rpm and stirring time of 10 minutes. The microstructure of the composites showed an even distribution of zircon particles. The composites' hardness improved with an increase in vol.% of zircon constituent part. Wear loss against different sliding distances and load was investigated through a Pinon-Disc wear testing apparatus with an L16 orthogonal array. Taguchi's parameter optimization demonstrated that material loss was influenced to a significant extent by adding Zircon. Wear resistance of the synthesized composite was investigated and verified using Analysis of Variance (ANOVA). Zircon content (39.33%) was found to be the most influencing factor on wear loss, followed by the applied load (36.80%) and sliding distance (21.54%). Zircon improves the properties of the composite through restricting the growth of dendritic arms in A356 alloy. In addition, reinforcement particles enhanced the strengthening of the composites through Orowan mechanism by inhibiting the movement of dislocations. ANOVA technique was successfully used to examine the effect of individual parameters on wear loss of A356 alloy-Zircon composites MMCs.

“…For this, four factors, i.e., normal load, sliding velocity, sliding distance, and filler (i.e., Mo) contents were considered, as shown in Table 2, in this present study; and a Taguchi L 25 (5 6 ) orthogonal array design was employed for one response, i.e., sliding wear. The S/N ratio analysis with lower-isbetter characteristics can be expressed as follows [18]:…”

Molybdenum-added biomedical alloy has been prepared using a high-temperature vertical vacuum casting technique with five (0, 1, 2, 3, and 4 wt%) diverse weight percentages. The density, microhardness, and sliding wear behavior of the fabricated alloys were studied, showing that the addition of molybdenum content in the metal-metal alloy (i.e., Co-30Cr) increases the density from 7.2 to 8.7 g/cc for 0-4 wt% of Mo, respectively. Similarly, the hardness of prepared biomedical alloy also increases from 653 to 720 HV on addition of 0-4 wt% Mo particulate, respectively. The hardness is investigated by the microhardness tester. The aim of this current research work is to optimized the sliding wear behavior of molybdenum-added Co-30Cr alloy for implant material by Taguchi experimental design technique at five different normal loads (5-25 N), sliding velocities (0.26-1.3 m/s), sliding distance (500-2500 m), and reinforcement, i.e., Mo (0-4 wt%) respectively. To obtain the optimum wear response of prepared biomedical alloy added with Mo contents, the Taguchi L 25 orthogonal array was implemented. The wear test is performed on a pin-on-disc tribometer against a hardened alloy steel (EN-31) disc under different operating conditions at room temperature. Afterwards, field-emission scanning electron microscopy and atomic force microscopy were utilized to analyze the microstructure, contour of wear mechanism, and 3D surface topography of samples after test run.
