Method for ultra-fast boriding
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.
1. A method of forming a boride material on a substrate, comprising the steps of,
providing a boriding component;
providing a substrate having a metal alloy having a first metal constituent comprising tungsten (W) and a second metal constituent comprising rhenium (Re);
disposing the substrate and the boriding component in an electrochemical bath;
establishing the electrochemical bath at a temperature of about 900°-1050° C.; and
forming a first metal constituent conforming boride layer comprising WB 4 on the substrate and a second metal constituent conforming boride layer comprising ReB 2 on the first metal constituent conforming boride layer.
2. The method of forming a boride material on a substrate of claim 1 , wherein the metal alloy consists essentially of W—Re 25% alloy.
3. A method of forming a boride material on a substrate, comprising the steps of,
providing a boriding component;
providing a substrate having a metal alloy having a first metal constituent comprising tungsten (W) and a second metal constituent comprising rhenium (Re), the metal alloy consisting essentially of W—Re 25% alloy;
disposing the substrate and the boriding component in an electrochemical bath;
establishing the electrochemical bath at a temperature of about 900°-1050° C.; and
forming a first metal constituent conforming boride layer on the substrate and a second metal constituent conforming boride layer on the first metal constituent conforming boride layer.
4. The method of claim 3 , wherein the first metal constituent conforming boride layer comprises WB 4 and the second metal constituent conforming boride layer comprises ReB 2 .
