Abstract

The paper shows the effect of thermo-chemical treatment: hardening, titanizing and boronizing of steel grade 56Si7 and 41CrAlMo7 applied for the production of yarn guides used in the textile industry. During the investigations the impact of treatment on the structure change, thickness, hardness and wear resistance of the achieved surface layers were determined. Study of the surface layer was conducted using both optical and scanning microscope. The effectiveness of carried out thermo-chemical treatment was verified in relation to the yarn guides working in industrial conditions. It has been proved that although the best results (highest hardness) was achieved after titanizing, also boronizing process guarantees sufficient wear resistance. The results of the research will be used to optimize the guides’ production process including friction and economic parameters.
