Abstract
Systems and methods presented herein relate to depositing a material coating on a substrate. For example, first layer of a material coating is deposited upon a substrate using a thermal spray. Further, a cooling flow is provided to the substrate. Additionally, a second layer of the material coating is deposited upon the substrate subsequent to depositing the first layer using the thermal spray.
Claims20
A method, comprising:
- depositing a first layer of a material coating upon a substrate using a thermal spray device;
- providing a cooling flow to the substrate via a cooling jet;
- and
- depositing a second layer of the material coating upon the substrate using the thermal spray device, wherein the second layer is deposited subsequent to depositing the first layer.

A method, comprising:
- depositing a first layer of a material coating on a radial bearing using a thermal spray device;
- cooling the radial bearing;
- and
- depositing a second layer of the material coating on the radial bearing using the thermal spray device.
1 more element
A system, comprising:
- a high velocity air fuel (HVAF) thermal spray device configured to provide a material spray to a radial bearing to form a material coated radial bearing;
- a cooling jet configured to provide a cooling flow of fluid to the radial bearing;
- a rotational actuator configured to rotate the radial bearing;
- and
- a controller communicatively coupled to the rotational actuator, the HVAF thermal spray device, and the cooling jet, wherein the controller is configured to:
- send a first control signal to the HVAF thermal spray device to provide the material spray;
- send a second control signal to the rotational actuator to rotate the radial bearing;
- and
- send a third control signal to cause the cooling jet to provide the cooling flow of the fluid
