Functionally graded coatings and claddings

A shear assisted extrusion process for producing cladded materials comprising:

• placing a cladding material and a material to be cladded in sequence into a container of a shear assisted extrusion device to from a billet;
• positioning the cladded material to contact a rotating scroll face of an extrusion die first and positioning the material to be cladded to contact the rotating scroll face of the extrusion die second as the two materials are fed through the shear assisted extrusion device at a preselected feed rate and impacted by the rotating scroll face, thereby extruding the billet through the extrusion die to generate a cladded extrusion product.
