description A method for improving the fracture toughness for aluminum-based diffusion coatings by thermal spray means to simultaneously apply aluminum, chromium, boron, and/or silicon onto a steel workpiece, followed by heat treatment of the workpiece for a sufficient time to cause the aluminum, chromium, boron, and/or silicon to diffuse into the workpiece. The resulting diffusion coating demonstrates improved fracture toughness and does not necessitate the use of a slurry.
