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 () and a beta-stabilizing material (); wherein the one or more elements () have an alpha-beta microstructure; assembling the one or more elements () and the beta-stabilizing material () such that the beta-stabilizing material () is adjacent to the one or more elements (); and heating the assembly such that the beta-stabilizing material () diffuses into an adjacent portion of the one or more elements (), causing the adjacent portion of the one or more elements () to have a beta microstructure which provides an increased erosion resistance.
