The role of subsurface deformation and strain localization on the sliding wear behaviour of laminated composites

The sliding wear behaviour of laminated composites of copper and amorphous Ni78Si10B12 fabricated by diffusion bonding was investigated. Unlubricated sliding tests were performed using a block-on-ring type wear machine in order to provide a direct comparison of the wear mechanisms in the metallic glass (Ni78Si10B12) layers and polycrystalline matrix (copper) and to determine the influence of the metallic glass layers on the overall wear …
