摘要

For the weight reduction of suspension coil springs for automobiles, high- strength steel has been developed. But, in general, strength and corrosion fatigue are contradictory. Then the technological basis is to raise durability and sag resistance, and further improvement of the corrosion fatigue strength is important. As a solution for the problem, element design which improved the performance against corrosion and optimum condition of shot peening process were studied. Thus high-strength suspension coil springs have superior corrosion fatigue strength, compared with the spring made of SAE9260 were developed. Moreover, as a new basic evaluation, corrosion fatigue test of springs with an artificial pit was worked out.
