Abstract

In engineering, as well as in other manufacturing industries, the use of compressed air is an important catch. Compressor production and service company Fonons, Ltd often deals with damage of screw type compressors, sometimes even irreversible. Damages that draw up to 15% are linked to strong wear out of compressor friction knot (rotors). This, in effect, reduces the optimum productivity and work efficiency of the compressor, increases losses between rotors. Compressor service time diminishes. Work foundation is the analysis of methods how to improve screw rotor surfaces. It is necessary as one of the concluding treatment operations in the manufacturing process. It may reduce the influence of the abrasive elements on the contact surface, diminish wear intensity, and increase the service time. Improved contact surface of rotors, which are coated with TiN coating by using physical vapour deposition (PVD) technology, is analysed within the framework. Surface quality control is executed with modern methods, including surface 3D topography analysis and coating quality estimation with the atomic force microscopy (AFM). The main materials are analysed characterizing parameters change according to the recommendation for manufacturing wear proof coatings.
