Abstract Scope |
With the development of additive manufacturing, new possibilities for the repair of damaged metal components are developing. Powder Laser Metal Deposition is one of these processes. In order to master and qualify this repair process, it must be characterized, controlled and optimized. The repair process consists of three main steps, consisting of removing the defect by machining, adding material by additive manufacturing and obtaining a good surface finish by finishing. During the repair process, the parts undergo thermal cycle control by preheating, inter-layers time or post-heat treatment, which will influence their mechanical properties. Repairs are performed by an OPTOMEC additive manufacturing machine according to a design of experiment that takes into account the substrate preheating temperature, the inter-layers time and the post-heat treatment. Characterizations will be undertaken to know the influence of the processing parameters and heat treatments on the mechanical properties, through microhardness mapping, tensile and Charpy impact tests. |
