Latest Patents
One of Polvi's latest patents is a method for forming a tight-fitting silver surface on an aluminum piece. This invention relates to creating a highly electroconductive surface by utilizing a eutectic join. The process involves gradually raising the temperature of the aluminum piece to remove the oxide layer, followed by transferring a silver piece to the cleaned surface. The contact point is then heated to generate a eutectic bond between the aluminum and silver.
Another significant patent is for the formation of a good contact surface on an aluminum support bar used in electrolysis. This method involves fabricating the support bar as a continuous piece and forming a highly electroconductive layer at its end. The metallic bond achieved through this process can be realized using thermal spray coating, resulting in an efficient electrode support bar.
