The results of this investigation demonstrate, in the first place, the need for the analysis of chemical composition changes and the importance of employing the spectral analysis of surface layers.
In view of the observed substantial changes in chemical composition, the operating conditions leading to these changes must be taken into account in the manufacturing technique with a view to selecting the most suitable composition of sintered sealing materials.
By using spectral analysis, it is possible to choose materials with higher stability of chemical composition and, consequently, wear-resistance characteristics. The existing materials should be employed more effectively by allowing for the changes taking place during operation.
