摘要
开发了一种适合于汽车紧固件磷化的新工艺:抛丸+复合磷化。复合磷化工艺的流程为:预脱脂—水洗—脱脂—水洗—表调—磷化—水洗—防锈—晾干—检查—浸油—沥干回收。批量生产证明,1kg浓缩剂可以处理紧固件250kg,300L磷化液日处理紧固件10t。该工艺可以强化高强度钢表面,大大提高钢材的机械性能和磷化膜的耐磨、耐腐蚀性能,而且成本低廉。
A new process of shot blast plus composite phosphating suitable for automotive fastener phosphating was developed. The process flow of composite phosphating is: pre-degreasing - rinse - degreasing - rinse - surface conditioning - phosphating - rinse - rusting prevention - drying - check-up -grease immersion - draining and recycle. Batch production proved that 250 kg fasteners were treated by 1 kg concentrated agent and 10 t by 300 L phosphating solution for a day. The process helps to strengthen high strength steel's surface and improve greatly the steel's mechanical property and phosphating film's wear resistance and corrosion resistance, and it is a low cost process as well.
