A multi-piece rim structure for a wheel includes a rim base 10, a bead seat ring 20 (ring member) and a lock ring 30. The bead seat ring 20 receives a load in a radial direction and an axial direction from a bead portion of a tire. An annular ridge 35 of the lock ring 30 can be received in an annular lock ring groove 15 of the rim base 10. A receiving groove 15a is formed in an inner surface of the lock ring groove 15 of the rim base 10. A sacrificial anticorrosion material 80 is embedded in the receiving groove 15a. The sacrificial anticorrosion material 80 includes metal such as zinc and aluminum that has a greater ionization tendency than iron that is a base material of the rim base 10 and the lock ring 30. Corrosion of the rim base 10 and the lock ring 30 can be suppressed by ionization of the sacrificial anticorrosion material 80.

Hexavalent chromium-free slurries are provided that are capable of achieving a full cure at temperatures as low as 330-450 degrees F., thus making the coatings especially suitable for application on temperature sensitive base materials.
