Abstract
An article of manufacture and method of forming a borided material. An electrochemical cell is used to process a substrate to deposit a plurality of borided layers on the substrate. The plurality of layers are co-deposited such that a refractory metal boride layer is disposed on a substrate and a rare earth metal boride conforming layer is disposed on the refractory metal boride layer.
Claims20
An article of manufacture of a borided material, comprising,
- a substrate having a metal constituent;
- a deposited layer of a metal alloy, including the metal constituent, boron, and an element selected from the group of group IVB, VB, VIB, Re and Si;
A method of forming a boride material on a substrate, comprising the steps of,
- providing a substrate having a metal constituent;
- providing a rare earth metal constituent;
- disposing the substrate and the rare earth metal constituent in an electrochemical bath;
- establishing the electrochemical bath at a temperature of about 900°-1050° C.;
- and
- co-depositing a first metal constituent confirming layer on the substrate and a second rare earth metal constituent conforming layer on the first metal constituent conforming layer.
