Abstract
The present disclosure provides downhole tools, methods for three dimensional printing hardfacing on such downhole tools, and systems for implementing such methods.
Claims20
A hardfacing system comprising:
- an application device including:
- a hardfacing heat source;
- and
- a downhole tool heat source;
- a first processor that:
- controls the hardfacing heat source to maintain a first temperature to cause a matrix material in hardfacing in the application device to melt without melting hard material particles in the hardfacing;
- and
- a second processor that controls movement of the application device to:
- place the downhole tool heat source at a first distance from a portion of the surface of the downhole tool for a time sufficient to form a melted portion of the surface.
