Surface treatment

Maschinenfabrik ALFING Kessler has been pioneering this technical challenge for decades. By using a wide range of technologies in surface treatment, Maschinenfabrik ALFING Kessler GmbH can meet almost all customer requirements for increased performance, reduced wear, increased fatigue strength and service life or the highest demands for corrosion resistance.

Induction hardening

One of our core competencies is the hardening of crankshafts. The hardening machines division was created in 1952 with independent planning, construction, assembly and sales of our inductive hardening systems in order to expand the existing product portfolio. This product is used by well-known engine manufacturers more than 500 times worldwide. Complex geometries for various components can be inductively hardened and tempered using state-of-the-art technology and know-how.

Gas nitriding

Gas nitriding is carried out with ammonia using the latest gas chamber furnaces. These defined thermochemical processes can be used for components with a wide variety of geometries up to a length of 3 m.

Carbonitriding

During carbonitriding, the components are treated with ammonia and additional carbon dioxide, which means that significantly shorter process times can be achieved.
