Summary on Grant Application Form |
It is the purpose of this project to develop a surface engineering treatment capable of sustaining high contact loads and thereby make possible the use of titanium alloys for applications such as transmission gears which are subjected to high Hertzian stresses and steam turbine blades, which are exposed to severe water droplet erosion. To withstand such stresses it is necessary to apply a thicker or deeper hardened surface layer than can be obtained on titanium using commercial processes. This will be achieved by melting and alloying the surface using a laser or electron beam to give a hard and coherent composite coating up to 1 mm thick. A thin surface film (such as PVD TiN) will be applied as may be necessary to withstand scuffing, and shot peening will be used to enhance fatigue properties. The present Consortium brings together acknowledged experts in laser and electron beam surfacing with a group of industrial partners representing foremost advances in the use of titanium for automobile engineering, steam turbine manufacture, aircraft construction and offshore installations.A mathematical model developed for nitriding steels will also be modified so as to map out the subsurface stresses in titanium components, and hence predict load bearing capacity of any specified surface engineered system. On completion of the programme the knowledge base will therefore have been increased to the stage where, given a designer's definition of the service conditions for a particular component, the process parameters needed can be predicted.
