Abstract

Compressor is developed to the direction of higher speed and load. As the vane of core component of the internal compressor assembly, the work condition is becoming worse. More attention is being attracted on surface treatment. Compressor vanes with surface treated by Nitriding Ni-P and DLC were selected to do the friction test and the impact on friction coefficient by duration, rate and load was also studied. Analysis on surface topography, chemical composition and bonding strength was performed by SEM and EDS, etc to investigate the different fractional behavior of relevant coating.
