“…This factor is influenced by the relatively low recrystallization temperature [ 29 ]. Uneven heat input during casting affects the grain sizes of Babbitt alloys [ 30 , 31 ]. Therefore, the solidification rate affects the microstructure and hardness of the coating.…”

This article presents the research results of depositing anti-friction coatings (Babbitt) using three different casting methods: static casting, flame soldering, and clad welding. Babbitt alloy coatings deposited with different casting methods are discussed and explained in terms of changes in the coating properties, such as the microstructure, hardness, strength, and chemical composition. The results showed significant differences in the aforementioned properties, depending on the chosen coating deposition method. The results of the tests confirmed the importance of using shielding gas during deposition to ensure the chemical composition of the coating. The analysis revealed that decreases in the amounts of antimony and copper in the Babbitt coating compared with the initial concentrations were influenced by selective evaporation, oxidation, and the coating process parameters associated with different coating methods. To maintain the desired balance of mechanical properties in Babbitt coatings, it is important to control the antimony and copper contents. Clad welding deposition using a non-consumable tungsten electrode and argon shielding gas achieved a chemically stable coating quite close to the initial chemical composition of the Babbitt alloy.

“…Babbitt also called white metal is widely used for sliding bearings because of its superior tribological properties like embeddability, conformability and antifriction ability [8][9][10][11]. Tin based Babbitt alloys are used for bearings in steam turbine and bushes in the field of aerospace [12,13]. Babbitt bushings are primarily prepared by centrifugal casting due to which there is segregation leading to low hardness and service life [14,15].…”

In the present study, a Babbitt-Ilmenite composite was developed via stir casting and the mechanical properties (hardness and tensile strength) of the composite were optimized using the Taguchi philosophy. The effects of variations in the percentage weight of Ilmenite, stirring speed and aging time on the mechanical properties of the composite were studied. Energy dispersive spectroscopy analysis confirmed the presence of Ilmenite in the metal matrix and uniform dispersal of Ilmenite in Babbitt was established via scanning electron microscopy. A Morphological analysis of the fractured tensile specimen was conducted to ascertain the type of failure. The Taguchi methodology and analysis of variance technique were proposed to predict the optimum levels of controllable parameters and to determine their percentage contribution to the optimization of mechanical properties of the composite. The percentage weight of Ilmenite and stirring speed were found to have significant effect on hardness while aging time was a significant parameter for the tensile strength of the composite. The predicted results were validated by confirmation experiments with a deviations of 1.6 % and 2.1 % for hardness and tensile strength respectively for single objective optimization. The weights of the responses were determined objectively and the multi-performance optimization of mechanical properties of the composite was performed using entropy based grey relational analysis (EGRA). The percentage weight of Ilmenite was only significant parameter with contribution of 30.65% for multi-performance optimization of mechanical attributes of composite using hybrid Taguchi grey relation analysis (TGRA). An overall improvement of 0.445 and 0.105 in the grey relation grade was reported using EGRA and TGRA respectively. The study concludes that the Babbitt /Ilmenite composite has superior mechanical properties both for single and multi-objective optimized conditions than the unreinforced tin Babbitt. The developed composite can be used for bearings in crankshafts, connecting rods and axles of automobiles
