A coated substrate has a substrate and a coating system having one or more ceramic layers. At least a first layer of one of the one or more ceramic layers is a columnar layer having as-deposited columns and intercolumn gaps.

A superalloy workpiece includes a superalloy substrate and an interface layer (IF-1) of essentially the same superalloy composition directly on a surface of the superalloy substrate. A transition layer (TL) of essentially the same superalloy and superalloy oxides or a different metal composition and different metal oxides is on the interface layer (IF-1). The oxygen content of the transition layer increases from the interface layer (IF-1) towards a barrier layer (IF-2) of super alloy oxides or of different metal oxides.

Methods of preventing or reducing cutter loss in a steel body PDC drilling tool may include applying a hardfacing layer on a surface of a PDC cutter pocket to form a covered PDC cutter pocket, the hardfacing layer comprising a metal binder and coated tungsten carbide particles; and bonding a PDC cutter into the covered PDC cutter pocket with a brazing material. Steel body PDC drilling tools may include a steel body, a PDC cutter, a PDC cutter pocket, and a hardfacing layer. Methods of preventing or reducing cutter loss in a steel body PDC drilling tool may include applying a hardfacing layer on a surface of a PDC cutter pocket of the steel body PDC drilling tool; applying a coated buffering layer on the hardfacing layer to form a coated PDC cutter pocket; and bonding the PDC cutter into the coated PDC cutter pocket with a brazing material.
