Innovations in coating/refurbishment/fabrication of cutting tools, dies, and high value machine components using automated laser cladding

在自动激光熔覆中，激光束熔化粉末颗粒和基材的薄层，形成直接粘合到基材上的涂层。通过传感器系统实时测量熔覆层的质量和几何形状，并通过智能控制器调节激光功率和熔覆速度，使熔覆层达到理想的质量和几何形状。在该工艺中，可以在不同的基材上沉积多种材料，形成厚度为0.1至3mm的涂层。使用自动激光熔覆工艺的连续分层技术可以生产更厚的涂层和大块3d部件。与传统工艺相比，该技术的高凝固速率和独特的加工条件允许生产具有改进性能的材料。

In automated laser cladding, a laser beam melts powder particles and a thin layer of the substrate to create a coating that is directly bonded to the substrate. Through a sensor system, the quality and geometry of the clad is measured in real time and using an intelligent controller, the laser power and the cladding speed will be adjusted to achieve the desired quality and geometry in the deposited layers. In this process, a great variety of materials can be deposited on different substrates to form a coating with a thickness of 0.1 to 3 mm. Thicker coatings and bulk 3-D parts can be produced by a successive layering technique using the automated laser cladding process. The high solidification rates and unique processing conditions of this technique allow the production of materials with improved properties compared to that of conventional processes.
