Introduction

Kyong-Tschong Rie is a notable inventor based in Braunschweig, Germany. He has made significant contributions to the field of plasma technology, particularly in the areas of surface treatment and hardening of materials. With a total of 2 patents, Rie's work has implications for various industrial applications.

Latest Patents

Rie's latest patents include a "Method and arrangement for plasma boronizing" and a "Process for hardening workpieces in a pulsed plasma discharge." The plasma boronizing method involves producing a boride layer on surfaces by supplying a gas mixture containing a boron-releasing gas to a reactor. This process generates a glow discharge using pulsed DC voltage, allowing for the creation of non-porous boride layers that enhance wear resistance in components such as gears and camshafts. The parameters for this process can be finely controlled, including voltage, pulse-duty factor, frequency, temperature, and gas mixture composition.

The second patent focuses on hardening workpieces of steel through carburizing and quenching. This is achieved by utilizing a plasma discharge in a vacuum with gaseous hydrocarbons. The method ensures a uniform hardness distribution, even for irregularly shaped workpieces, by carefully managing the total pressure and pulse durations during the carburization process.
