Wright, R R

A method is described for etching a molybdenum or molybdenum-rich alloy surface to promote the formation of an adherent bond with a subsequently deposited metallic plating. In a typical application, the method is used as a pre-treatment for surfaces to be electrolessly plated with nickel. The pre-treatment comprises exposing the crystal boundaries of the surface by anodizing the surface in acidic solution to form a continuous film of gray molybdenum oxide and removing the film.
