AB  - Inspired by the application of metallic glass sheet as face material for improving the performance of golf clubs, the present work was aimed to explore the application of thin-film metallic glass (TFMG) coatings for enhancing the performance of strings. In order to achieve this aim, badminton strings were coated with TFMG coatings of different thicknesses. The compositions of these TFMG coatings were analyzed using an electron probe micro-analyzer. The amorphous structure of the film was verified using X-ray diffraction. In order to simulate the strung tension of the string in the racquet, the coated string was subjected to different pounds of tensile loading and was subsequently impacted by a steel ball to study both energy loss and the coefficient of restitution (COR). It was observed that while the TFMG coatings could reduce the energy loss and increase the COR at impact, they exerted negligible effects on the tensile strength of the string. In addition, there existed an optimum coating thickness, beyond which cracking of the coating would occur, degrading the beneficial effects of the coating.
