“…In the future, we will focus mainly on current trends in the improvement of the artificial hip joint and the technologies of its arthroplasty (THA), because it is this operation that is performed most often and it is characterized by the same problems that are observed with arthroplasty of the knee, shoulder, elbow, and other joints although structurally they are significantly different. This approach can be considered generally accepted and in many scientific studies the most significant problems characteristic of all artificial joints are not identified with a specific type of joint (see, for example, Römmelt et al, 2019;Shirani et al, 2019;Von Skrbensky et al, 2019;Yang et al, 2019;Zhang L. et al, 2019). Moreover, in most of the studies devoted to artificial joints, artificial hip joints are still used as examples (Bhalekar et al, 2019;Xu H. D. et al, 2019).…”

There is a global tendency to rejuvenate joint diseases, and serious diseases such as arthrosis and arthritis develop in 90% of people over 55 years of age. They are accompanied by degradation of cartilage, joint deformities and persistent pain, which leads to limited mobility and a significant deterioration in the quality of life of patients. For the treatment of these diseases in the late stages, depending on the indications, various methods are used, the most radical of which are methods of joint arthroplasty and, in particular, total arthroplasty. Currently, total arthroplasty is one of the most effective and high-quality surgical operations at the relevant medical indications. However, complications may also arise after it, leading, inter alia, to the need for repeated surgical intervention. In order to minimize the likelihood of complications, the artificial joints used in total arthroplasty and the technology of their fabrication are constantly being improved, which leads to the emergence of new designs and methods for their integration with living tissues. At the same time, at the moment, the improvement of traditional designs and production technologies has almost reached the top of their art, and their further improvements can be insignificantly or are associated with the use of the most up-today technologies, allowing for friction couples with low tribological properties to provide for them high ones, for example, gradient increase hardness in the couple titanium alloy on titanium alloy. This paper presents the current state of traditional technical means and technologies for joint arthroplasty. The main attention is paid to the analysis of the latest technologies in the field of joint arthroplasty, such as osseointegration of artificial joints, the improvement of materials with the property of osteoimmunomodulation, the improvement of joint arthroplasty technologies based on the modeling of dynamic osteosynthesis, as well as the identification of possible unconventional designs of artificial joints that contribute to these technologies, predictive assessment of areas for technologies improvement.

“…14,15 It is frequently used to finish the components used in aerospace, automotive, medical implants, mold and dies, pump, and to remove recast layer from the products manufactured by wire electrical discharge machining (WEDM) process. 16,17 Some researchers used AFF to finish different types of gears focusing on reduction of their surface roughness only. Xu et al 18 used AFF for finishing helical gears and reported significant reduction in surface roughness of flank surfaces of gears with high processing efficiency.…”

This paper reports on reduction of noise and vibrations of cylindrical and conical gears through simultaneous reduction in their microgeometry errors, functional parameters, and surface roughness by finishing them with abrasive flow finishing (AFF) process. Previously identified optimum values of AFF medium viscosity and finishing time were used during AFF of the chosen gears. Noise and vibrations characteristics of the unfinished gears and the AFF finished gears were studied by varying motor speed and applied load at four levels each. An indigenously developed test rig was used for spur and straight bevel gears whereas drivetrain diagnostic simulator was used for helical gears. Indigenously developed dual flank roll tester was used to evaluate functional parameters of the unfinished and the best finished gears by AFF process. It was found that AFF process simultaneously reduced microgeometry errors, functional parameters, maximum and average values of surface roughness of spur, helical, and straight bevel gears. It reduced noise and vibration by 5.2 dBA and 5.3 m/s2 for spur gears, by 3.4 dBA and 7.5 m/s2 for helical gears, and by 4.6 dBA and 4 m/s2 for straight bevel gears. This study proves that AFF is an easy-to-operate and effective process for reducing noise and vibrations of cylindrical and conical gears through simultaneous reduction in their microgeometry errors, functional parameters, and surface roughness values. Outcome of this work will be helpful for various manufactures and users of different types of gears.

“…They reported a surface roughness of 0.039 mm for the femoral head. Despite the significant advantages of the AFF process, [18][19][20][21][22][23][24][25] the non-uniform surface finish was seen in the microscopic images; indicating that the fixture was not designed according to the geometry of the femoral head.…”

Total hip arthroplasty (THA) is one of the most well-known orthopedic surgeries in the world which involves the substitution of the natural hip joint by prostheses. In this process, the surface roughness of the femoral head plays a pivotal role in the performance of hip joint implants. In this regard, the nano-finishing of the femoral head of the hip joint implants to achieve a uniform surface roughness with the lowest standard deviation is a major challenge in the conventional and advanced finishing processes. In the present study, the inverse replica fixture technique was used for automatic finishing in the abrasive flow finishing (AFF) process. For this aim, an experimental setup of the AFF process was designed and fabricated. After the tests, experimental data were modeled and optimized to achieve the minimum surface roughness in the ASTM F138 (SS 316L) femoral head of the hip joint through the use of response surface methodology (RSM). The results confirmed uniform surface roughness up to the range of 0.0203 µm with a minimum standard deviation of 0.00224 for the femoral head. Moreover, the spherical shape deviation of the femoral head was achieved in the range of 7 µm. The RSM results showed a 99.71% improvement in the femoral head surface roughness (0.0007) µm under the optimized condition involving the extrusion pressure of 9.10 MPa, the number of finishing cycles of 95, and SiC abrasive mesh number of 1000.
