Introduction

Laurence J Romana is a notable inventor based in Guadeloupe Antilles, France. He has made significant contributions to the field of ceramic surface engineering. His innovative approach focuses on the controlled removal of ceramic surfaces through advanced ion implantation techniques.

Latest Patents

Romana holds a patent for a method titled "Controlled removal of ceramic surfaces with combination of ions." This patent describes a process for tailoring or patterning the surface of ceramic articles. The method involves implanting ions to a predetermined depth into the ceramic material at selected surface locations. The ions are implanted at a fluence and energy sufficient to damage the lattice structure of the ceramic material. This process creates bi-axially strained near-surface regions, which are then treated with energy pulses from collapsing, ultrasonically-generated cavitation bubbles in a liquid medium. This technique allows for the selective removal of ion-damaged regions, enabling precise surface modifications.
