A method for making a gas turbine engine component includes the steps of: providing an unfinished gas turbine engine component; directing a laser beam on a selected surface portion of the engine component to prepare the selected surface portion before at least one of a subsequent coating and bonding step; and depositing at least one layer of an abradable material, a subassembly of the component or a thermal barrier coating on the selected surface portion.

A method for making a gas turbine engine component includes the steps of: providing an unfinished gas turbine engine component; and selectively patterning a selected surface portion of the engine component by focusing a laser beam on the selected surface portion to improve lubricant distribution between the patterned surface of the engine component and a surface of another engine component in contact with the patterned surface during engine operation.
