Paper XII (i) The effect of continuous au sputter deposition on the enhancement of growth of transfer particles

Gold atoms are sputter deposited by argon gas onto the friction surfaces of a disk specimen during friction between a pin and disk of Sn and of Zn. For the range of deposition rates 0.05 to 0.20 angstrom/sec, the growth of transfer particles is enhanced by the deposition, resulting in the generation of larger wear particles and more wear than those without deposition. The shear strength of Sn and Zn with an Au impurity is assumed to be higher than that of pure Sn or Zn, and this is attributed to be the cause for the enhancement of growth of transfer particles by the deposition.
