METHOD FOR ADHERING COBALT-CHROMIUM-TUNGSTEN PROTECTIVE COATING TO BLADE COMPRISING VANADIUM-CONTAINING TITANIUM ALLOY AND BLADE COATED BY SAID METHOD |
摘要 |
A method of laying a protective coating on a blade (1) made of a titanium alloy including vanadium. Vanadium powder is deposited on the portion of the blade (1) to be coated, the temperature of the powder is then raised to a temperature slightly greater than the melting point of vanadium. A powder of a cobalt-chromium-tungsten alloy is then deposited on the layer of vanadium, and this powder is raised to a temperature greater than its melting temperature and less than the melting temperature of vanadium. A blade made of an alloy of titanium including vanadium is characterized in that the blade includes a coating layer (5) of cobalt-chromium-tungsten alloy at its periphery, said layer being at least 1 mm thick and covering an underlayer of vanadium (6) which has a thickness lying in the range 0.5 mm to 1.5 mm. The resulting blade has very high resistance to abrasion by water droplets. |
