摘要: This invention teaches a new class of materials that can be used to manufacture hairsprings and/or other components of mechanical watches, and methods for manufacturing these components. The new class of materials is crystalline compounds, including, but not limited to, gallium arsenide, extrinsically doped gallium arsenide, extrinsically doped silicon, gallium nitride, extrinsically doped gallium nitride, gallium phosphide, extrinsically doped gallium phosphide, and quartz. This invention also teaches laminated/coated crystalline compounds. The lamination/coating may be applied by one of the following methods, including but not limited to: plasma enhanced chemical vapor deposition, atomic layer deposition, sputtering, electron beam evaporation, and thermal evaporation. Using crystalline compounds, in particular extrinsically doping the crystalline compounds, affords the possibility to controllably alter the mechanical, electrical, thermal, magnetic, and/or other properties of the watch components. These properties can be further altered by applying single or multiple laminates/coatings of varying thicknesses and/or geometries.
