His innovative work focuses on enhancing the performance and durability of cutting tools through advanced coating techniques.

Latest Patents

Among his latest patents is an oxide coated cutting tool that features a body partially coated with refractory layers. One of these layers consists of α-Al2O3, which is characterized by equiaxed grains with an average size of less than 1 µm. This layer exhibits a bimodal grain size distribution, containing coarser grains in the range of 0.5-1 µm and finer grains of less than 0.5 µm. The unique microstructure is achieved by temporarily halting the gases required for the growth of the α-Al2O3 layer and introducing TiCl. Another patent involves a cutting tool coated with a fine-grained κ-Al2O3 layer, which also has equiaxed grains with an average size of less than 0.5 µm. This microstructure is developed by periodically introducing a silicon halide, preferably SiCl4, during the Al2O3 coating process.
