Surface and structural properties of titanium coating deposited onto AIN ceramics substrate by friction surfacing process

AIN ceramics was coated with Ti by friction-surfacing method where the energy of kinetic friction was directly transformed into heat and delivered in its sp. amt. directly to the formed joint between Ti layer and substrate material. The coating was studied for face structure, metal-log. properties, morphol., stereostructure and thickness. The coating was 3-6 mu m thick, defect-free and rough enough (0.404 and 1.95 mu m) to be soldered to metals.
