“…The sintered carbide was composed of: 58 wt% of WC, 31.5 wt% of (TiC + TaC + NbC), and 10.5 wt% of Co. Such a material obtained a mass density of 10.7 g/cm 3 and hardness of 1430 HV. The wear tests were conducted under conditions of dry friction (unlubricated sliding contact) using the load P = 49 N and the specimen speed of 0.26 m/s, resulting from the rotational speed n=250 min -1 and the external diameter of the specimen (20 mm).…”

“…There were attempts to improve tribological properties of the stainless steels using the methods widely applied for constructional or tool steels, such as nitriding, carburizing or boronizing [2][3][4][5][6][7][8][9][10][11]. Glow discharge assisted low-temperature nitriding of 316L steel was investigated [2,3]. This process (at 440°C for 6 h) caused the formation of a thin layer (4 µm) composed of chromium nitrides (CrN) as well as of austenite supersaturated with nitrogen [2].…”

The increase in process temperature up to 550°C (823 K) resulted in producing the layer of the thickness about 20 µm [3].

A B S T R A C TAustenitic 316L steel is well-known for its good resistance to corrosion and oxidation. Therefore, this material is often used wherever corrosive media or high temperatures are to be expected. The main drawback of this material is very low hardness and low resistance to mechanical wear. In this study, the laser boriding was used in order to improve the wear behavior of this material. As a consequence, a composite surface layer was produced. The microstructure of laser-borided steel was characterized by only two zones: re-melted zone and base material. In the re-melted zone, a composite microstructure, consisting of hard ceramic phases (borides) and a soft austenitic matrix, was observed. A significant increase in hardness and wear resistance of such a layer was obtained. K E Y W O R D Slaser boriding, austenitic steel, microstructure, hardness, wear resistance

“…Much research work has been done in the field of combining thermochemical treatments with additional surface technologies for improving the compound properties under high tribological stresses, especially with respect to enhanced load‐bearing capacities . A common combination is a thermochemical treatment prior to a hard‐coating deposition . In this surface compound, the layer of expanded austenite N serves as a supporting layer for the hard coating.…”

Functional Surface Layers on Stainless Steels Generated by Means of EB Cladding and Nitrocarburizing

et al. 2014

The combined treatment of electron beam (EB) cladding and subsequent nitrocarburizing of duplex stainless steels aims at enhancing the wear behavior and simultaneously maintaining their outstanding corrosion resistance. By means of electron beam cladding using a Co-based wire surface coatings are generated that exhibit enhanced surface hardnesses up to 500 HK0.01 as well as improved corrosion properties. The nitrocarburizing of these coatings results in surface layers with hardness values above 1100 HK0.01 and a thickness of about 10 mm. For treatment temperatures of up to 420°C these layers consist of, among other phases, expanded austenite and are free of chromium precipitations. The wear coefficient is significantly reduced and the corrosion resistance is maintained. The functional effectiveness of such surface matrix compounds is based on the combination of high surface hardness and good corrosion resistance, which are maintained, even if layer defects occur within the nitrocarburized layer, due to the improved corrosion behavior of the EB coating underneath.
