The present invention relates to methods of enhancing the surface properties of soft alloys by using a high energy beam. In particular embodiments, the methods can also allow for beam-based welding of such soft alloys to another metal component.

Methods for site-specific enhancement of soft magnetic alloys

A combination of materials and processing parameters have been developed for hermetic seals for electrical feedthroughs in high performance applications. A glass-ceramic forms a hermetic seal between a stainless steel shell and a platinum-nickel-based (Pt—Ni) pin alloy for electrical feedthroughs. The glass-ceramic is processed to develop a coefficient of thermal expansion (CTE) slightly higher than the pin alloy but lower than the stainless steel. The seal system employing the new processing conditions and Pt—Ni-based pin alloy alleviates several problems encountered in previous seal systems and improves the hermetic connector performance.

Hermetic electrical feedthrough comprising a Pt—Ni-based pin alloy

A method of providing a hermetic, electrical connection between two electrical components by mating at least one metal pin in a glass-ceramic to metal seal connector to two electrical components, wherein the glass-ceramic to metal seal connector incorporates at least one metal pin encased (sealed) in a glass-ceramic material inside of a metal housing, with the glass-ceramic material made from 65-80% SiO, 8-16% LiO, 2-8% AlO, 1-5% PO, 1-8% KO, 0.5-7% BO, and 0-5% ZnO. The connector retains hermeticity at temperatures as high as 700&#xb0; C. and pressures as high as 500 psi.
