A method of forming a wear surface of a wheel of a rail vehicle, the method comprising:
- depositing a first alloy powder having a first composition onto a main body of the wheel, wherein the first alloy powder includes 0.19% Carbon (C), 3.1% Chromium (Cr), 0.19% Manganese (Mn), 0.15% Silicon (Si), 0.6% Molybdenum (Mo), and 2.1% Nickel (Ni);
- plasma transfer arc welding the first alloy powder onto the main body of the wheel to form a first alloy layer secured to the main body of the wheel;
- depositing a second alloy powder having a second composition over the first alloy layer, wherein the second composition differs from the first composition, wherein the second alloy powder includes 0.25% C, 3.0% Cr, 0.21% Mn, 0.18% Si, 4.9% Mo, and 3.2% Ni;
- and
- plasma arc welding the second alloy powder onto the first alloy layer to form a second alloy layer.
A method of forming a surface of a component, the method comprising:
- depositing a first alloy powder having a first composition onto a base structure of the component, wherein the first alloy powder includes 0.19% Carbon (C), 3.1% Chromium (Cr), 0.19% Manganese (Mn), 0.15% Silicon (Si), 0.6% Molybdenum (Mo), and 2.1% Nickel (Ni);
- plasma transfer arc welding the first alloy powder onto the base structure of the component to form a first alloy layer secured to the base structure of the component;
- depositing a second alloy powder having a second composition over the first alloy layer, wherein the first composition differs from the second composition, wherein the second alloy powder includes 0.25% C, 3.0% Cr, 0.21% Mn, 0.18% Si, 4.9% Mo, and 3.2% Ni;
- and
- plasma arc welding the second alloy powder onto the first alloy layer to form a second alloy layer.
