Abstract
A method of manufacturing an aerofoil structure to have a portion with an increased erosion resistance, the method comprising: providing one or more titanium elements (2, 4, 6) and a beta-stabilizing material (8); wherein the one or more elements (2, 4, 6) have an alpha-beta microstructure; assembling the one or more elements (2, 4, 6) and the beta-stabilizing material (8) such that the beta-stabilizing material (8) is adjacent to the one or more elements (2, 4, 6); and heating the assembly such that the beta-stabilizing material (8) diffuses into an adjacent portion of the one or more elements (2, 4, 6), causing the adjacent portion of the one or more elements (2, 4, 6) to have a beta microstructure which provides an increased erosion resistance.
Claims12
A method of manufacturing an aerofoil structure to have a portion with an increased erosion resistance, the method comprising:
- providing three or more titanium elements and a beta-stabilizing material assembled in a laminate such that the beta-stabilizing material is interleaved between the titanium elements in an alternating arrangement;
- wherein the titanium elements have an alpha-beta microstructure;
- heating the assembly such that the beta-stabilizing material diffuses into an adjacent portion of the titanium elements, causing the adjacent portion of the titanium elements to have a beta microstructure which provides an increased erosion resistance.
