Final Report - SEFUCO (High performance self-lubricated multifunctional coating for demanding industrial applications)

Funded under: FP6-SME

Abstract

SEFUCO was a European funded project within the Sixth Framework Programme (FP6) whose principal aim was to develop a self-lubricating, low friction and low wear coating capable to work under non-lubricated conditions.

The specific technical objectives of the project were:
- stability testing of solid lubricants during the powder manufacturing processes and during the thermal spraying process;
- the development of a manufacturing technology for multicomponent powder containing Solid lubricant (SL) for thermal spraying;
- thermal spraying and optimisation of spraying process for SL containing powders, evaluation and characterisation of manufactured coatings;
- determination of tribological, wear and corrosion properties of coatings.

The main achievements of the project were the following:
- On the powder processing site one of the main achievements was the successful creation of powder for thermal spraying where three alloying elements were integrated into each powder particle. Innovative powder solutions consist of a hard carbide phase, metal matrix phase and solid lubricant additions, some of them alloyed in a nanostructured scale;
- The thermal spraying of these experimental powders yielded good coating quality. Solid lubricant additions are very sensitive for thermal loads and could easily decompose or even evaporate during the coating process. It was possible to manufacture coatings in which the added solid lubricant did not decompose during the spraying process;
- After the quality of powders and coatings was approved that it was sufficient, coatings were sent for tribological testing. The testing of coating was extensive: wear resistance of coatings was tested with abrasive wear tests, the Coefficient of friction (COF) was measured at three different temperatures and corrosion resistance was measured with two different methods. Solid lubricant additions did reduce the wear resistance of the coatings slightly.
