N2 - Al–4Cu–20Pb alloy was spray deposited at a gas pressure of 1.4 MPa and melt flow rate of 1.6 kg min−1. The microstructure of the preform exhibited equiaxed morphology with grain size varying from 20–25 μm. Uniform distribution of submicron size lead particles were observed in the Al-matrix. Wear testing, employing a pin-on-disc type set-up, revealed considerably low wear rate of the alloy compared to that of similar alloys reported in the literature. Scanning electron microscopy of the wear track on specimens and debris dislodged from surfaces showed a mixed oxidative-cum-adhesive mechanism of wear of this alloy in the test condition employed in the present study.
