This paper presents research of influence electrolyte plasma carbonitriding on tribological properties of R6M5 high-speed steel. Shows perspectiveness of carbonitriding high-speed steels in electrolyte plasma. The results of research demonstrated increasing wear-resistance of R6M5 steel after carbonitriding in electrolyte plasma. Under the same test conditions by the method of scratch-test have been determined that the depth of the scar of a modified layer has become less in comparison with the original sample, which indicates a significant increase of wear-resistance and hardness of the surfa

Abstract:
Abstract Carbonitriding enhances properties of many steels and is therefore an attractive alternative for surface hardening of steel components in the mechanical industry. However, pore formation in the carbon and nitrogen enriched surface layer may occur under certain process conditions. For a given steel and case depth specification, pore formation can be managed by reducing the nitrogen activity of the carbonitriding atmosphere below a defined limit, depending on process temperature and process time. Recent progress in process control allows automatic and independent adjustments of the carb

Abstract Carbonitriding is a process in which carbon and alloy steel gears are held at a temperature above the transformation range in a gaseous atmosphere of such composition that the steel absorbs carbon and nitrogen simultaneously.

Carbonitriding is generally regarded as a modified gas carburizing process, rather than a form of nitriding.

Abstract In the carbonitriding process, both carbon and nitrogen are diffused into the steel, can be carried out in a salt bath or in a furnace gas atmosphere. It is a modified carburizing process but is mostly done at a slightly lower temperature and for shorter time than carburizing. This process is one of the widely used heat treatments for surface hardening. Nonetheless, there are challenges associated with the process performance and reliability. In industry, numerical modeling can be an efficient approach with lower cost and less time to help determine and optimize process parameters.
