Title: Innovations by Per Mårtensson

Introduction

Per Mårtensson is a notable inventor based in Nacka, Sweden. He has made significant contributions to the field of cutting tools, particularly through his innovative patent. His work focuses on enhancing the performance and efficiency of machining processes.

Latest Patents

Mårtensson holds a patent for an α-alumina coated cutting tool. This cutting tool is composed of one or more layers of refractory compounds, with at least one layer being single-phase α-alumina. The unique feature of this invention is its pronounced columnar grain-structure and strong texture in the [300]-direction. The alumina layer is preferably deposited using Chemical Vapor Deposition (CVD). The preferred microstructure and texture are achieved by adding a second metal halide and a texture modifying agent to the reaction gas. This innovation has shown several important improvements in the machining of steel and cast iron, particularly in the machining of nodular cast iron.
