    • PROBLEM TO BE SOLVED: To provide a coil spring for vehicle suspension, excellent in corrosion resistance.SOLUTION: A first shot peening process and a second shot peening process are implemented on a spring element wire of 50-56 HRC in hardness in the temperature range of 150-350°C. In the first shot peening process, a first shot whose shot size is at least 1.0 mm is used. In the second shot peening process, a second shot whose shot size is smaller than for the first shot is used. The spring element wire to which compressive residual stress is applied according to the first and second shot peening processes has: a residual stress increase portion in which compressive residual stress increases in the depth direction from a surface; a residual stress peak portion in which compressive residual stress becomes maximum; and a residual stress decrease portion in which compressive residual stress decreases in the depth direction of the spring element wire from the residual stress peak portion. Moreover, in the residual stress decrease portion, a portion having compressive residual stress equivalent to the compressive residual stress of the surface, exists in a depth in excess of an allowable pit depth of the spring element wire.
    • 要解决的问题:提供一种用于车辆悬架的螺旋弹簧,具有优异的耐腐蚀性。解决方案:在温度范围内的硬度为50-56HRC的弹簧元件线上实施第一喷丸硬化处理和第二喷丸硬化处理 为150-350°C。 在第一次喷丸硬化处理中,使用其射出尺寸至少为1.0mm的第一枪。 在第二次喷丸硬化处理中,使用了其投射尺寸小于第一次投篮的第二次投篮。 根据第一和第二喷丸处理方法施加压缩残余应力的弹簧元件线具有:残余应力增加部分,其中压缩残余应力在距离表面的深度方向上增加; 残余应力峰值部分,其中压缩残余应力变得最大; 以及残留应力减小部,其中压缩残余应力在弹簧元件丝的深度方向上从残余应力峰值部分减小。 此外,在残余应力减少部分中,具有与表面的压缩残余应力相当的压缩残余应力的部分存在于弹簧元件线的允许凹坑深度以上的深度。
