介绍了一种激光诱导金属表面氧化着色技术。氧化膜的每种颜色对应于一个工艺色度系数，该系数考虑了样品在暴露于具有纳秒持续时间和有效作用时间的激光脉冲序列后的温度。该系数可用于计算在金属上形成特定颜色的激光曝光制度。显示了在不锈钢AISI 304和商业2级钛表面上获得的膜的组成与其颜色和色度坐标之间的相关性。
A technology of laser-induced coloration of metals by surface oxidation is demonstrated. Each color of the oxide film corresponds to a technologic chromacity coefficient, which takes into account the temperature of the sample after exposure by sequence of laser pulses with nanosecond duration and effective time of action. The coefficient can be used for the calculation of laser exposure regimes for the development of a specific color on the metal. A correlation between the composition of the films obtained on the surface of stainless steel AISI 304 and commercial titanium Grade 2 and its color and chromacity coordinates is shown.
