Abstract
Processes for producing coated surfaces and coatings are described. The processes can be used to produce a surface coating comprising an alloy layer. The produced alloy layer can include molybdenum or tungsten in combination with one or more of nickel, cobalt, chromium, tin, phosphorous, iron, magnesium or boron or other materials.
Claims28
A method of depositing an alloy layer on a substrate, the method comprising:
- providing a cathode comprising an electrically conductive base material used as the substrate that receives the alloy layer, an anode associated with the cathode, an electrodeposition bath and a power supply connected to the cathode and the anode associated with the cathode;
- providing a current from the power supply connected to the cathode and the anode associated with the cathode to electrodeposit an alloy layer on the cathode in the electrodeposition bath, wherein the electrodeposition bath comprises a molybdenum ionic species or a tungsten ionic species and at least one ionic species of a second element selected from the group consisting of nickel, cobalt, chromium, tin, phosphorous, iron, magnesium and boron, wherein the electrodeposition bath is heated to a temperature above 45 deg. Celsius, and wherein the electrodeposited, alloy layer comprises molybdenum or tungsten and the second element.
