为开发高强度钢板用长寿命模具，研究了采用复合（双）射处理和低温氮化控制模具表面织构的方法。混合喷丸由于其润滑作用而改善了粘扣性能，而低温渗氮对于通过热处理减少变形是有用的，其具有足够的抗磨损的1500 HV的硬度。利用快速傅立叶变换（FFT）分析模具材料的表面纹理，发现高频和低频的频谱幅值之比对应于产生粘扣的载荷。
The methodologies of controlling the surface texture of die by hybrid (double)-shot treatment and nitiding at a low temperature were examined for the development of long life cycle die applied to the high strength steel sheets. Hybrid-shot improved the galling property because of its lubricating effect, while nitriding at low temperature which is useful for decreasing distortion by heat-treatment had sufficient hardness of 1500 HV for anti-abrasion. Surface texture of die material, evaluated by using Fast Fourier Transformation (FFT) analysis revealed that the ratio of the spectrum amplitude between high and low frequencies was corresponding to the galling generation load.
