New materials and manufacturing processes

Bullet Development of steels with improved properties

 

One of Ceit's primary activities is optimizing manufacturing processes in order to improve steels and superalloys for energy applications:

• Microstructural control for improved material performance under harsh service conditions: high temperature applications, deep sour gas wells, etc.

• Microstructure–property relationships

• Degradation and failure mechanisms: aging, oxidation, creep, corrosion, etc. Cyclic conditions and the overlapping of mechanisms: thermomechanical fatigue, creep-fatigue. Temperature gradients and thermal shock, wear, radiation. Mechanical properties.

• Surface treatments (i.e. shot peening). Investigation of surface reactions and mechanisms at high temperature.

• Modeling

• Bimetallic bonding and production of components through thermomechanical processes, hot-pressing, hot isostatic pressing and high vacuum furnaces.

• Hot isostatic pressing for powder consolidation: atomization, capsule design and manufacture, hot isostatic pressing, final machining. Alternative to forging plus machining.

Bullet New materials for diamond tools. Free-sinter technology, hot-press, Co-based powders, commercial pre-alloyed powders, etc.

  • Full powder metallurgy processing of hardmetal (WC-Co) and cermet (TiC, TiCN, TiB2, WB4) tools.

  • Design of metal binders serving as alternatives to cobalt.

  • Near net shape processing.

  • Thermal treatments.

  • Microstructural analysis and mechanical characterization in accordance with standards.

  • Joining methods: welding, brazing, shrink fitting.

  • Development of tools for metal cutting and hot and cold chipless shaping of metals. 

  • Tribological components and inserts for wear applications.

  • Failure analysis.

  • Diamond tools for primary and secondary cutting and polishing.

  • Free sintering , hot-press and HIP technologies.

  • Co-based powders and alternative prealloyed powders.

  • Industrial diamond quality.

  • Coatings. Application to civil engineering.

Bullet Design of ceramic materials for extreme applications (harsh environments): combustion, condensing boilers, electric furnaces, etc.
