PROCEDE POUR FABRIQUER UNE AUBE EN TITANE ALPHA BETA COMPRENANT UN INSERT DE TITANE BETA METASTABLE, ET AUBE REALISEE PAR UN TEL PROCEDE |
摘要 |
A turbine blade is made by shaping a blade body (2) of alpha beta titanium with a surface to receive an edge section (3) of metastable beta titanium, heat treating and hardening the section (3) and welding it to the body using a laser or electron beam to minimise local heating. Also claimed are (i) repairing such a blade by cutting away a worn edge section and welding on a new section in a similar manner; and (ii) the blades so made or repaired. |
