“…The nanoscale surface finish of biomedical implants made of metals such as 316L stainless steel (SS 316L) and titanium alloys is essential for their biocompatibility [ 11 ]. Karthikeyan et al [ 92 ] developed a rotational magnetorheological abrasive flow finishing (R-MRAFF) process to finish SS 316L, and the impact of surface roughness on hemocompatibility was assessed by a platelet adhesion experiment.…”

“…For example, vascular stents mainly apply traditional laser technology. However, the laser treatment of metal materials with high mechanical properties and high melting points can cause problems such as ablation and defects, affecting the therapeutic effect after implantation [ 11 ]. Various coating methods exist at this stage, however, these coatings often carry specific properties that cannot be balanced.…”

“…Three trials were performed at different locations on each specimen, and the average value was determined [18][19][20]. The HN varied depending on the weight percentage of the reinforcement mixed with Al7475.The highest hardness value (85.9 Hv) was obtained in sample L13, with parameters of 800rpm stir speed, [21,22] 15 minutes stir time, 8wt% reinforcements, and 80MPa squeeze pressure. On the other hand, the lowest hardness value (72.5 Hv) was recorded in sample L4, with parameters of 500rpm stir speed, 30 minutes stir time, 8wt% reinforcements, and 120MPa squeeze pressure.…”

This study focuses on the preparation of Al-based hybrid composites using AA7475 as the main alloy reinforced with two materials, ZrO2 and SiC. The combination of stir-squeeze processing techniques was employed to create various specimens by varying four parameters: Stir-speed, Stir-time, reinforcements, and squeeze pressure. Taguchi design was utilized to generate specimens for analyzing their mechanical properties, specifically tensile strength, hardness, and porosity.The results indicated that the highest porosity (4.44%) was observed in the L16 test, with a combination of 700rpm stir speed, 25 mins stir time, 2wt% reinforcements, and 80MPa squeeze pressure. On the other hand, the lowest porosity (2.61%) was found in the L7 test, with 800rpm stir speed, 30 mins stir time, 2wt% reinforcements, and 100 MPa squeeze pressure.Regarding tensile strength (UTS), the maximum value (285.23MPa) was achieved in the L13 experiment, while the minimum value (187.58 MPa) was observed in the L1 experiment. This variation in UTS can be attributed to the applied load, the strengthening effect of the reinforcements, and the grain size of SiC.

“…As per literature, the alloying elements are used to reduce the weight and increase the weight to strength ratio by 15 to 20%. These properties make it ideal for a component used in applications where deformation occurs due to cyclic loads especially in cars and mini commercial vehicles [17,18]. The alloying material composition of the failed crankshaft is given in table 1.…”

The performance and safety of any vehicle relies on proper design of crankshaft. Crankshaft failure occurs mainly due to the combination of imbalance and minor deflections when the materials is subjected to combined bending and twisting. Failure analysis is crucial to identify the causes and modes of failure, in order to improve the service life of automotive crankshafts and prevent accidents. This research analyses the root cause of failure by testing a failed crankshaft of a twin cylinder diesel engine used in mini commercial vehicle runs around 80000 km. The important research gap identified as that there is no fool-proof techniques and validation procedures are followed in the service stations during its life cycle period. This investigation of a failed crankshaft provides detailed composition of material, its micro structure and mechanical properties. Further, rotary analysis, experimental modal analysis and mechanical testing of materials are helpful in characterizing proper materials to be selected and analyzing the root cause of failure. The experimental setup helps to test a crankshaft and its specimen as per ASTM testing procedures and the results are correlated with numerical analysis using ANSYS software. The objective of this investigation is to provide insights through failure analysis to the designers and manufacturers, thereby improve the reliability and safety of automotive crankshafts, ensure safe operation of the vehicle, and eventually minimize financial losses.
