Titanium article having improved corrosion resistance

A titanium article having improved corrosion resistance, comprising a titanium substrate having directly attached to a minor surface portion thereof by welding an appliqué of a platinum group metal or platinum group metal alloy, wherein the appliqué is of the platinum group metal is present in an area less than 1% (excluding 0) of the surface area to be protected or any minor surface area for the platinum group metal alloy, whereby said article exhibits better corrosion resistance than said article without said appliqué.

A titanium article having improved corrosion resistance, comprising a titanium substrate having directly attached to a minor surface portion thereof by plating an appliqué of a platinum group metal or platinum group metal alloy wherein the appliqué of the platinum group metal is present in an area less than 1% (excluding 0) of the surface area to be protected or any minor surface area for the platinum group metal alloy, whereby said article exhibits better corrosion resistance than said article without said appliqué.

A titanium article having improved corrosion resistance, comprising a titanium substrate having directly attached to a minor surface portion thereof by vapor deposition an appliqué of a platinum group metal or platinum group metal alloy, wherein the appliqué of the platinum group metal is present in an area less than 1% (excluding 0) of the surface area to be protected or any minor surface area for the platinum group metal alloy, whereby said article exhibits better corrosion resistance than said article without said appliqué.
