With a total of 2 patents, his work has advanced the techniques used in manufacturing and material processing.

Latest Patents

One of his latest patents is a chemical milling method for the interiors of narrow tubes. This innovative method involves etching patterns on the interior surface of narrow metal tubes. The process begins with dipping a thin tube into a maskant solution to a specific depth, ensuring that etching is localized. A thixotropic maskant with high edge thickness is essential for achieving sharp, even etched edges. The tube is then placed in an etching solution that is agitated and replenished as needed. This method results in a smooth fillet and prevents leaks of etchant through the maskant.

Another notable patent by Gross involves aqueous chemical milling solutions for aluminum and aluminum alloys. These solutions contain a caustic and a nitrate or nitrite, with the option to include a diol or polyol such as ethylene glycol or glycerin. His work in this area has contributed to the development of effective chemical milling processes.
