To explore the process parameters of the laser directly-induced coloring for a stainless steel surface, we used a nanosecond laser to induce the coloring of the stainless steel surface, and various colors such as dark blue, black, gray, pink, green, purple, gold, yellow, brown, and maroon were obtained. While the maroon color has not been reported in other researches of laser-induced stainless steel surface coloring. The three elements in the Lab color space under the aforementioned laser-induced coloring process parameters were measured. The results show that the color difference ΔE of the samples is less than 7, the color of the color block surface is stable, uniform, and undamaged, and the obtained laser-induced process parameters are repeatable. This research topic has great application value in industries such as automobiles and electronics.
