REPAIR OF COMPONENTS USING ADDITIVE MANUFACTURING WITH IN-SITU COLD WORKING

摘要

Aspects are directed to removing a portion (402) of a component (300) that includes wear to generate a void in the component (300), where a material of the component (300) has a first microstructure, depositing a filler material (508) in the void, subjecting the filler material (508) to a cold working technique to compress the filler material (508), and applying a heat treatment to cause the filler material (508) to have a second microstructure that is matched to the first microstructure. Aspects are directed to a case of an engine, including: a first portion with a first material that has a first microstructure, and a second portion with a second material that has a second microstructure, where the second microstructure is matched to the first microstructure, where the second material includes a plurality of layers, and where at least one layer of the plurality of layers includes a compressive residual stress.
