A system and method of bonding is disclosed which is suitable for providing a strong interlocking adhesive bond between two surfaces. At least one bonding surface is provided with multiple layers of spherical shaped protrusions. The multilayer spherical bonding surface is formed from the substrate and therefore is continuous. Many methods may be employed to form this surface, including the lost wax casting process. Such bonding surfaces provide good interlocking properties for bonding agents such as epoxy resins and ceramics. In addition, the uniform curvature of the spherical particles themselves reduces points of stress thereby substantially reducing or even eliminating the formation of stress fractures.
