    • Laser energy is directed at a substrate to mobilize, vaporize and react a constituent (primary) element (e.g., carbon) contained within the substrate, so as to modify the composition (e.g., crystalline structure) of the constituent element, and to diffuse the modified constituent back into the substrate, as an adjunct to fabricating a coating (e.g., diamond or diamond-like carbon) on the surface of the substrate. This creates a conversion zone immediately beneath the substrate, which transitions metallurgically from the composition of the underlying substrate to a composition of the coating being fabricated on the surface of the substrate, which results in diffusion bonding of the coating to the substrate. Additional (secondary) similar (e.g., carbon) or dissimilar elements may be introduced in a reaction zone on and above the surface of the substrate to augment the fabrication of and to determine the composition of the coating. The laser energy is provided by a combination of an excimer laser, and Nd: YAG laser and a CO2 laser, the output beams of which are preferably directed through a nozzle delivering the secondary element to the reaction zone. The reaction zone is shielded by an inert (non-reactive) shielding gas (e.g., N2) delivered through the nozzle. A flat plasma is created by the lasers, constituent element and secondary element on the surface of the substrate and the flat plasma optionally extends around the edges of the substrate to fabricate a coating thereon. Pre-treatment and coating fabrication can be performed in conjunction with one another (in-situ). Alternatively, a substrate can be pre-treated to characterize its surface for subsequent coating. In either case, certain advantageous metallurgical changes are induced in the substrate due to the pre-treatment. The processes (pre-treatment and coating fabrication) are suitably performed in ambient, without preheating the substrate and without a vacuum. Substrates of numerous geometries, sizes and shapes, such as flat cutting tool inserts as well as round cutting tools, are readily coated in this manner. The lasers are directed at any suitable angle (including coaxial) relative to the substrate and/or the plasma.
    • 激光能量被引导到衬底上以动员,蒸发并反应包含在衬底内的成分(主要)元素(例如,碳),以便改变构成元素的组成(例如晶体结构),并且扩散 改进的组分返​​回到基底中,作为在基底表面上制造涂层(例如,金刚石或类金刚石碳)的辅助物。 这在基底的正下方产生转化区,该转化区从冶金学上从下面的基底的组成转变成在基底的表面上制造的涂层组合物,这导致涂层扩散到基底上。 可以在衬底表面上和上方的反应区中引入另外的(次级)类似(例如碳)或不同元素,以增加涂层的组成并确定涂层的组成。 激光能量由准分子激光器和Nd:YAG激光器和CO2激光器的组合提供,其输出光束优选地通过将次要元件传送到反应区域的喷嘴引导。 反应区被通过喷嘴输送的惰性(非反应性)保护气体(例如N 2)屏蔽。 由衬底表面上的激光器,构成元件和次要元件产生平坦的等离子体,并且平坦的等离子体可选择地围绕衬底的边缘延伸以在其上制造涂层。 预处理和涂层制造可以彼此结合(原位)进行。 或者,可以对基底进行预处理以表征其表面以用于随后的涂覆。 在任一情况下,由于预处理,在衬底中诱发某些有利的冶金变化。 工艺(预处理和涂覆制造)在环​​境温度下适当地进行,而不预热基板并且没有真空。 具有许多几何形状,尺寸和形状的基底,例如平切刀具刀片以及圆形刀具,以这种方式容易地涂覆。 激光器相对于衬底和/或等离子体指向任何合适的角度(包括同轴)。

    • Energy, such as from a UV excimer laser (712), an infrared Nd:YAG laser (714) and an infrared CO2 laser (716) is directed through a nozzle (722) at the surface of a substrate (702) to mobilize and vaporize a carbon constituent (e.g., carbide) within the substrate (e.g., steel). An additional secondary source (e.g., a carbon-containing gas, such as CO2) (720) and an inert shielding gas (e.g., N2) are also delivered through the nozzle. The vaporized constituent element is reacted by the energy to alter its physical structure (e.g., from carbon to diamond) to that of a composite material which is diffused back into the substrate as a composite material.
