With a total of 3 patents to his name, his work focuses on enhancing the durability and performance of materials through innovative treatment processes.
Latest Patents
One of his latest patents is a treatment process for depositing a layer of carbon in vapor phase. This process aims to impart resistance to frictional wear, corrosion resistance, and color to treated articles. It involves subjecting the surface of the article to a thermochemical pretreatment under electric plasma in a vessel filled with reactive species such as nitrogen and hydrogen. The reactive species diffuse into the metal matrix, forming a diffusion sublayer, followed by the deposition of a carbon layer in vapor phase.
Another significant patent is the deposition process of a ceramic coating on a metallic substrate. This invention focuses on depositing a ceramic-type coating based on carbides, nitrides, or carbonitrides of various metallic elements. The coating is applied at low temperatures in the vapor phase using organo-metallic precursors, preceded by a reactive ionic pickling in a reducing atmosphere.
