The wettability of a distillate water drop on the isotropicAl20Sn1Cu samples increases as the a-Al grain size decrease,reaching the best condition for samples produced by melt-spinningwith a wheel speed of 1.5 m/s.Increasing the cooling rate at 1.4 106 K/s (wheel speed of 7 m/s) leads to a detriment in the surface properties (hardness andwetting) because of the crystallographic texture of the a-Alphase.The melt-spun Al20Sn1Cu sample produced at a wheel speed of1.5 m/s has improved surface properties as required to improve theplain bearing friction material. That is, higher hardness to resisthigher loads and improved wettability to preserve the lubricant onthe bearing surface. Moreover, that processing condition leads toobtain the alloy with enough thickness (450e500 mm) that allowsmanufacturing the plain bearing avoiding several rolling passesnormally required to reduce the thickness of the friction material.
