研究目的
To study the capabilities of color laser marking (CLM) on chrome-plated products based on the study of factors influencing the process and development of laser processing modes for creating color images on a metal surface with a chrome plating.
研究成果
The research demonstrated that the thermophysical characteristics of the base material significantly influence the color image formation during laser marking of chrome-plated surfaces. Different colors were obtained on steel and brass samples under the same processing conditions, highlighting the importance of material properties in CLM.
研究不足
The study is limited by the specific materials used (Steel 08 and Brass L63) and the chrome plating thickness of 1 μm. The predictability of the resulting color in CLM is still a challenge due to insufficient understanding of all influencing factors.
1：Experimental Design and Method Selection:
The study involved using samples of steel and brass with identical chrome plating thickness to assess the influence of material thermophysical characteristics on color formation during laser processing.
2：Sample Selection and Data Sources:
Samples were Steel 08 and Brass L63 with a chrome plating thickness of 1 μm.
3：List of Experimental Equipment and Materials:
A pulsed fiber laser HanslaserMars 20J was used for laser marking, alongside Markingsoftware
4：0 for setting laser processing modes. Experimental Procedures and Operational Workflow:
Samples were processed under the same laser parameters and marking modes to observe color formation differences.
5：Data Analysis Methods:
The obtained color images were identified using the NCS color system to standardize color perception.
