Supercorroding galvanic cell alloys for generation of heat and gas

Claim 1

Supercorroding galvanic cell alloys for generating heat and hydrogen gas upon activation in an electrolyte, comprising: a. uniform mechanical alloy produced by the repeated flattening, fracturing and cold welding together of active anodic powered metal and passive cathodic powdered material constituents in an inert atmosphere to form minute mechanically alloyed composite galvanic cell particles of completely homogeneous mixture; b. said anodic and cathodic powdered particles being substantially atomically clean and absent of oxides on their surfaces and being coupled into micro-cells having strong mechanical bonds and intimate atomic-level electrical contact; said micro-cells having extremely short current path lengths between the alloyed constituents; c. said anodic powdered metal and passive cathodic powdered material being mechanically alloyed to a point substantially less than saturation hardness for providing desired homogeneity and optimum reaction time in said electrolyte; d. each of said uniform mechanically alloyed galvanic cell particles consisting of an active anodic metal matrix having numerous smaller particles of passive cathodic material trapped and dispersed throughout said active anodic metal matrix in a characteristic homogeneous layered structure; e. said active anodic metal being powdered magnesium; f. said passive cathodic powder material being selected from any of iron, copper, titanium, chromium, carbon, and nickel, including combinations thereof; g. said mechanically alloyed galvanic cell particles being operable to corrode at a predictable and rapid rate in a desired electrolyte for producing heat and gas by proper selection of constituents and percentages thereof and the homogeneity of the alloy; said mechanically alloyed galvanic cell particles having optimum electrical contact between active and passive material and no electrode gap to maintain resulting in minimal internal electrical resistance and improved reaction rates in suitable electrolyte; wherein maximum corrosion rate and efficiency is provided with minimum electrolyte bath length, high exposed surface area ratio, strong welded bonds and less than 10 -4 ohms resistance for external currents to flow through between the corroding cathode and anode material pairs of the supercorroding galvanic cell alloyed particles.
