When choosing to turn laminated stainless steel Ti-gold, it is advisable to consider using a Ti-gold overlay film as an alternative, which is flexible and cost-effective in achieving the desired color effect. While PVD coating is a high-quality surface treatment option, it is not the only choice available. With simpler application processes, overlay films can provide good visual appeal and protection. Ensure that the selected film has good wear resistance and weather resistance to suit the intended use environment. It is also recommended to conduct small-scale tests before large-scale application to ensure that the color and effect of the chosen material meet expectations.
