现有技术中，生产汽车配件的钢材为普通的中低含量合金钢，因这些挡货架金属配件在使用功能上一般是频繁的运动部件，磨损率很高，更换频繁，增加了维护成本；寻找到一种提高硬度和耐磨性能，同时零件表面耐热性能高的中低含量的合金钢就显的非常重要。
由于被滚压的表层金属塑性变形，使表层组织冷硬化和晶粒变细，形成致密的纤维状，并形成残余应力层，硬度和强度提高，从而改善了工件表面的耐磨性、耐蚀性和配合性。
发明内容

3）、喷漆后的架体毛坯进行真空、升压烤漆阶段，各阶段的参数及过程为：真空范围：常压～0.025MPa，温度200-250℃，时间为0.2～0.4h；升压范围：0.025～1.1MPa，温度210-220℃，时间为0.3～0.6h。
