Currently restoration and strengthening of a component working surface for structural purposes (objects of stamping equipment, highly loaded assemblies of cars and units, and components operating in corrosive media) is conducted mainly by means of welding operations that do not provide a functional coating and as a result do not provide the life required for a restored or strengthened object. This work concerns a study of laser cladding for restoration of working surface for stamping equipment. Work on laser cladding is conducted on the basis of DMD (Direct Metal Deposition) technology performed in a FL-Clad–R-4 robotic unit that includes a KUKA KR-120 robot. Cobalt-based material is used to create a coating and the substrate (stamp) material is AISI L6 steel. This provides solution for the production problem with selection of regimes for a coating with the required physical and mechanical properties for stamp surface hardening, as well as specific compositions of powder materials used to develop technology for object mass production. Attention is drawn to the fact that alloy used for powder production must have the required physical and mechanical properties and during cladding (after cooling) a coating must not experience thermal stresses and also has the required adhesion.

使用机器人复合体 FL-CLAD–R-4 通过激光熔覆修复模具设备

目前，用于结构目的的部件工作表面（冲压设备的对象、汽车和单元的高负载组件以及在腐蚀性介质中运行的部件）的修复和加固主要通过不提供功能涂层的焊接操作进行，并且作为结果不提供恢复或加固对象所需的寿命。这项工作涉及对用于修复冲压设备工作表面的激光熔覆的研究。激光熔覆工作基于 DMD（直接金属沉积）技术在 FL-Clad–R-4 机器人单元中执行，该单元包括 KUKA KR-120 机器人。钴基材料用于制作涂层，基材（印章）材料为 AISI L6 钢。这为生产问题提供了解决方案，即选择具有冲压表面硬化所需物理和机械性能的涂层，以及用于开发物体大规模生产技术的粉末材料的特定成分。需要注意的是，用于粉末生产的合金必须具有所需的物理和机械性能，并且在熔覆过程中（冷却后），涂层必须不能承受热应力，而且必须具有所需的附着力。
