Elements of refrigeration compressors, may be exposed to various types of wear processes. The presence of the refrigerant makes the lubricating and anti-wear properties of the oil-medium mixture much worse than the oil without refrigerant. The paper presents the effect of using the Ti-AI-Cr-N coating on the surface condition of friction junction occurring in compressors of chillers. The tests were carried out using a model friction machine simulating the element of a refrigeration compressor.
