With a total of 4 patents to his name, Lewis has developed innovative methods and systems that enhance the understanding and management of corrosion in metals.

Latest Patents

One of his latest patents is the "Hydrogen permeation probe method." This method allows for the in situ measurement of atomic hydrogen permeation into carbon steel from process streams under operating conditions of up to 3000 psi and temperatures up to 300°F. The method includes providing a probe assembly that consists of a test specimen electrode and a negatively charged counter electrode in a fluid-tight reservoir containing an electrolyte. The probe assembly is mounted directly in contact with a process stream, and electrical conductors are passed from the probe through a supporting, electrically non-conductive isolator positioned between a mounting assembly and the probe. By maintaining a constant voltage across the electrodes, the method enables direct measurement and recording of permeation current flow between the probe electrodes.

Another significant invention is the "High-speed corrosion-resistant rotating cylinder electrode system." This apparatus is designed for monitoring the corrosion rates of metals. It includes an electrochemical/permeation cell body that contains a fluid whose corrosive effect is to be monitored. The cell body has a base with an aperture, and a counter electrode/reference electrode complex is mounted within the cell. The system features a cylindrical working electrode and a rotatable system shaft that extends through the aperture into the cell body. The working electrode is positioned for rotation within the cell body, and a cone-shaped cap made from a corrosion-resistant polymeric material is placed above the working electrode to reduce vortex phenomena. A motor is connected to the system shaft for rotation, and all components of the test apparatus are made of corrosion-resistant materials.
