“…This increase in hardness and compressive strength may be attributed to the fact that alloying element results in good mixing that causes the mechanical integrity of the ingredients. Similar results have also been reported in previous studies [36][37][38].…”

Optimum selection of appropriate biomaterial with unlike properties for the femoral head material is one of the toughest tasks. Therefore, in this article, a series of implant materials for the femoral head by vacuum casting induction furnace containing cobalt‐30chromium (Co‐30Cr) as a base material and three alloying elements (i. e. molybdenum, nickel and tungsten) were developed and evaluated for physical, mechanical and tribological properties. Density, hardness, compressive strength, coefficient of friction and volumetric wear were considered as material selection criterions. The weight of each criterion has been determined by entropy method, while the ranking of the alternatives has been carried out by the preference ranking organization method for enrichment evaluations (PROMETHEE) method. From this ranking results, it is found that the cobalt‐30chromium‐4molybdenum‐1nickel‐2tungsten (Co‐30Cr‐4Mo‐1Ni‐2W) material at given parameters is the best implant material for the femoral head component of hip joint replacement.

“…It was observed in biomedical Co 61 Cr 35 Ti 4 alloys treated at 400°C for 10 h and quenched in water [29]. The same r phase was found to coexist with hcp-Co and fcc-Co phases in Co 80 Cr 20 dental alloys produced by direct solidification [30].…”

“…This is because chipping failure will occur in machined components with coarse grain structures as consequence of reducing the accuracy of the marginal fit of restorations [5]. Because the Ni can cause skin allergies or cancer in living organisms [3,6], note that novel Ni-free CoCrW has been extensively studied because of their excellent biocompatibility and strong bonding strengths of metal-porcelain, which has high potential for dental applications [7]. Yamanaka et al [8] prepared Co-29Cr-9W cast alloys with carbon concentrations in the range 0.01-0.27 mass%.…”
