Abstract

This invention relates to objects having a corrosion resistant surface improving the overall corrosion resistance of the object relative to the core material, preferably being titanium or titanium based. The surface layer preferably contains at least 80% of a refractory metal such as tantalum, or an alloy based on one or more refractory metals, To ensure a good adhering of the surface to the base material an alloy layer is created between a core element and the surface layer having a thickness at least twice that of the surface layer, where the alloy layer itself has corrosion resistant properties.
