Abstract [en]

Sputtered Ni and Ti layers were investigated as a diffusion barrier to substitute electroplated Ni between Ti-Si-C and Ti-Si-C-Ag nanocomposite coatings and Cu or CuSn substrates. Samples were subjected to thermal annealing studies by exposure to 400 degrees C for 11 h. Dense diffusion barrier and coating hindered Cu from diffusing to the surface. This condition was achieved for electroplated Ni in combination with magnetron-sputtered Ti-Si-C and Ti-Si-C-Ag layers deposited at 230 degrees C and 300 degrees C. and sputtered Ti or Ni layers in combination with Ti-Si-C-Ag deposited at 300 degrees C.
