Abstract

Rhenium is a hard material, capable of being electroplated from aqueous electrolytes to form wear-resistant coatings. Difficulty has existed in obtaining relatively thick plated coatings of rhenium. The following bath composition and conditions make possible the preparation of leveled, nonporous coatings of rhenium greater than 3 mils in thickness: Rhenium ion 20 g/1 NH(4)OH Conc. 80 ml/1 Phosphate ion 200 g/1 Current density 2.5-5.0 ASI Temperature 60 degrees C. pH 5.7.

Bath Composition for Plating Thick Wear Resistant Rhenium

Rhenium is a hard material, capable of being electroplated from aqueous electrolytes to form wear-resistant coatings. Difficulty has existed in obtaining relatively thick plated coatings of rhenium. The following bath composition and conditions make possible the preparation of leveled, nonporous coatings of rhenium greater than 3 mils in thickness: Rhenium ion 20 g/1

NH(4)OH Conc. 80 ml/1

Phosphate ion 200 g/1

Current density 2.5-5.0 ASI

Temperature 60 degrees C.

pH 5.7.

The source of the rhenium ions is preferably one half from potassium perrhenate and one half from sodium perrhenate.
