This article will delve into his latest patents, career highlights, collaborations, and ultimately highlight his impact on the field of innovations and patents.

Latest Patents:

One of Vassen's notable recent patents is titled "Method for producing non-oxide ceramic powders" (patent code not provided). This invention outlines a method for producing non-oxide ceramic powders, such as nitrides, carbides, borides, or at least one MAX phase with a specific composition. The method involves mixing selected starting materials with a metal halide salt, compressing them into pellets, and subjecting them to synthesis with another metal halide salt. The process also includes enveloping the pellet with another metal halide salt, compressing it again, and subjecting it to a salt bath until the melting temperature is reached. The addition of melted silicate is optional and aids in preventing salt evaporation at high temperatures. One notable advantage of this method is that it can be carried out in the presence of air, offering increased convenience and flexibility in the manufacturing process.

Another noteworthy patent by Vassen is titled "Construction element having a bond structure for a turbo engine, method for the production of a construction element having a bond structure for a turbo engine, and turbo engine having a construction element having a bond structure." This invention focuses on a construction element designed specifically for use in turbo engines, particularly aircraft engines. The element consists of a bond coat with a specific bond structure, above which a ceramic coat is applied on a base. The lateral faces of the bond structure lack undercuts but feature Peak and/or Trough structures. The angles of these structures are carefully designed to optimize performance, with the peak structures having mean peak angles below 90 degrees or even 45 degrees, and the trough structures having valley angles between 90 and 170 degrees.
