1. A system comprising:
a powder source;
a powder delivery device;
an energy delivery device; and
a computing device, wherein the computing device is configured to:
control the powder delivery device to deliver a metal powder to a surface of an abrasive coating;
control the energy delivery device to deliver energy to at least one of the abrasive coating or the metal powder to cause the metal powder to be joined to the abrasive coating, wherein the abrasive coating comprises a metal matrix and abrasive particles at least partially encapsulated by the metal matrix;
control the energy delivery device to deliver energy to an abrasive coating after deposition of the abrasive coating, wherein the abrasive coating comprises a metal matrix and abrasive particles at least partially encapsulated by the metal matrix; and
control the energy delivery device to scan the energy across a surface of the abrasive coating to re-melt or reflow the metal matrix.
