Abstract: Dental prosthetic restoration coatings made of dielectric materials, methods of fabricating the same, as well as methods of testing dental prosthetic restorations are provided. A prosthetic restoration coating can include dielectric materials such as Al2O3, ZrO2, SiNx, SiC, and SiO2. Application can take place using plasma enhanced chemical vapor deposition (PECVD) methods, and alternating materials can be used to achieve desired anticorrosive, structural integrity, hardness, adhesion, and color characteristics. A testing method can include immersing a test device in solutions of differing pH, with or without abrasive steps. The cycling can include an acidic solution and a basic solution, with an optional neutral solution. As the abrasive step, a chewing simulator can be utilized.

Abstract: A method of using a magnetostrictive material to achieve a high magnetomechanical coupling factor comprising building an internal anisotropy energy into the magnetostrictive material and applying a tensile or compressive stress to the magnetostrictive material with the built-in internal anisotropy energy. The internal anisotropy energy is built into the magnetostrictive material by annealing the magnetostrictive material under an annealing stress or a suitable magnetic field. For a positive magnetostrictive material, when the annealing stress is compressive, the stress applied to the annealed material under operation is tensile, and when the annealing stress is the tensile, the stress applied to the annealed material under operation is compressive.

Abstract: An elongate structure having a magnetostrictive material composition is subjected to tensile stress in the longitudinal-axial direction, thereby generally orienting the magnetization of the elongate structure in the longitudinal-axial direction. Electrical current is conducted through the elongate structure and/or through at least one adjacent elongate conductor, thereby generally orienting the magnetization of the elongate structure in the transverse direction, generally in parallel with the transverse direction of the magnetic field concomitant the conduction of current through the elongate structure. The elongate structure magnetostrictively contracts due to the (generally 90°) repositioning of the magnetization of the elongate structure.

Abstract: A positive magnetostrictive material such as a ferromagnetic alloy is subjected to a magnetic field during annealing treatment while being heated for a predetermined period of time at an elevated temperature below its softening temperature followed by cooling resulting in a treated ferromagnetic material having high tensile strength and positive magnetostriction properties for enhancing use thereof under tensile loading conditions. Such treatment of the ferromagnetic alloy may be augmented by application thereto of a compressive stress.
