Latest Patents
One of Hoffman’s latest patents focuses on a method of increasing the useful life of tool steel cutting tools. This method involves cleansing the cutting bit through ion beam subjection while ensuring that the temperature does not exceed 350 degrees Celsius. The process includes coating the cleansed bit with condensed sputtered atoms of titanium and boron, achieving a coating thickness of 2-6 microns. An argon or krypton beam of ions is accelerated to 1300-1800 volts to sputter a titanium diboride target arranged as a cathode. The sputtering process lasts for 5-10 minutes while the bit is heated to approximately 200 degrees Celsius, all conducted under a soft vacuum of about 4-6 milli-torr.
