Graded titanium based coatings by combining thermal spray and PVD technologies

There is a rapid growth in demand for improved surface performance in many priority industrial sectors. There have also been rapid developments in methods of surface engineering and in tribological understanding. There is accordingly an exciting opportunity for cost effective industrial exploitation of materials with desirable properties. Among these materials, titanium and its alloys occupy an important place: their use in sectors such as aerospace and biomedical has already started and they are very promising candidates for an increasing number of industrial applications, provided some weak points are solved
