“…However, their applications have been limited due to their poor tribological properties and susceptibility to fretting fatigue (FF) damage [3][4][5]. To solve the problem of FF damage, the anti-wear and anti-fatigue properties of Ti alloys should be simultaneously improved.…”

This work reported a comparison between the wear and fretting fatigue (FF) behaviors of a Cr-alloyed layer and a Cr-Ti solid-solution layer. The hardness and toughness of both layers were evaluated to support this comparison. The results showed that the Cr-alloyed layer had high surface hardness but poor toughness, while the Cr-Ti solid-solution layer had excellent toughness but low hardness. The FF properties of the modified Ti6Al4V alloy depended on the trade-off between two factors: wear resistance and fatigue resistance. Although the Cr-alloyed layer could effectively resist the wear in fretting areas, its poor toughness caused the fatigue resistance to drop sharply and hence led to a premature failure in FF test. Due to the relatively good fatigue resistance, the Cr-Ti solid-solution layer had slightly higher FF life than that of the Cr-alloyed layer; however, its low hardness resulted in severe wear in correspondence with the fretting area and thus a failure to improve the FF properties of Ti6Al4V alloy. When combined with shot peening post-treatment, the FF life of both layers increased by about three times compared to that of the Ti6Al4V alloy. A further study showed that the poor toughness or low hardness still exerted negative influence on combination-treated samples.

The crankshaft is the part of an engine which translates reciprocating linear piston motion into rotation. Automobile crankshaft failure, apart from poor maintenance culture, is caused by age and distance covered. These attributes which caused crankshaft failure were investigated using questionnaire administration and oral interviews of the maintenance expert and experienced personnel in the three selected crankshaft maintenance shops in Akure, Nigeria based on six popular crankshaft brands. Information/data on failure rate and failure consequence thresholds were established and served as a decision rule on the basis at which optimal reconditioning process, replacement and interchangeability system of the crankshaft components were identified on the occurrence of failure rate (R 1 ) and failure consequence (β 1 ). Computer algorithm was developed for the software package, using Microsoft Visual C# computer language. The software was tested to determine their level of performance. The results generated from the application of these systems were categorised into six scenarios whereby the MC230 Class gave the best result. The software will be veritable tools in predicting crankshaft failure in automobile, manufacturing, and machine tools industries, for prompt solution.

“…The contributing factor for failure mechanism of the crankshaft is due of the bending and torsional stresses with the fluctuation of loads during the operational time period [1,2,3,5,6,32]. The optimal desired reliability life prediction (Fig.…”

“…By analysing and predicting the reliability based physical nature of failure through a stochastic process. It is known that the crankshaft is designed to last a lifetime with a significant safety limit [2][3]5] but its failure is still unavoidable due the variation of loading sequence during its operating condition. Therefore, the consequences of failure of the crankshaft over its operating period would cause a more severe failure towards the engine block and the other connecting subcomponents [6,22].…”
