With a total of 2 patents, his work has garnered attention for its innovative approaches and practical applications.

Latest Patents

Sagel's latest patents include a groundbreaking design for valve seat rings made of basic cobalt (Co) or cobalt/molybdenum (Co/Mo) alloys. This invention focuses on a cylinder head for internal combustion engines, which features a metallic valve seat ring formed by a thermally sprayed homogeneous layer of the specified alloy. The composition of the alloy is critical, as the sum of the Co and Mo content exceeds 50 percent by weight, while the iron (Fe) content remains below 5 percent by weight. Additionally, he has developed a method for thermally spraying the valve seat ring using an arc wire spraying process, which employs at least two filler wires and/or composite wires. The essential Co portion in the deposited layer is delivered by the jacket of the filler wire and/or the matrix of the composite wire.

Another significant invention by Sagel is the electric arc wire burner. This device is designed for spraying an electric arc and comprises at least two burner tubes for feeding electrodes in the form of wire. The electrodes are guided through the burner tube towards the surface of the object to be coated. The wire is managed by a deflection device that includes several rotationally mounted guiding elements and/or sliding elements, allowing for precise control during the spraying process.
