Abstract

See full text

This invention relates to an object having a corrosion resistant surface that is also sufficiently ductile to let the surface, or the whole object, be mechanically modified without creating cracks or other weaknesses undermining or damaging the corrosion resistance. The surface layer preferably contains at least 80% of a refractory metal, such as tantalum, and an alloy layer is created between a core element and the surface layer having the needed ductility and adhering abilities.
