Erosion shield, method of fabricating a shield, and method of fabricating an article having a shield

摘要

A method 100 of fabricating a near-net shape erosion shield, a method of forming a shielded article, and a near-net shape erosion shield are provided. The method 100 of fabricating a near-net shape erosion shield includes providing 110 a base 109, positioning 120 an energy source 107 relative to the base 109, and depositing 130 at least one wear resistant material over the base 109 with an energy beam 105 from the energy source 107. The at least one wear resistant material 111 deposited on the base 109 forms the near-net shape erosion shield 101 configured to be positioned on a turbine component. The method 100 of forming a shielded article includes removing the base from the near-net shape erosion shield 101, and securing the near-net shape erosion shield to a turbine component. The near-net shape erosion shield 101 includes a near-net shape erosion-resistant portion configured to be positioned on a turbine component 201.
