The steel surface also accepted chrome plating better than the forged I-beam axles, so hot rodders often preferred them for their aesthetic qualities, as well.

Its structure and character were reviewed, and the synthetic methods, including CVD, ion beam sputtering, laser ablation, ion plating and ion irradiation et al., were completely introduced.

It can also avoid pretermission of plating, burnout of zinc layer on weld beam and heat affected zone, and other limitations on the inner surface of fuel tank made of galvanized sheet.
