“…This was ascertained by the obtained microstructure photos, which clarify that carbides grow longer and thicker and their distribution becomes more uniform in sample (ESR3, M41) comparing to sample (IF, M41). The ME parameters that obtained for the new appeared magnetic phase (forth sextet) was found in agreement with those belongs to α-Fe 2 O 3 [16]. The appearance of such iron oxide phase may be due to the fact that the refining process of metal from inclusion may accompany by secondary contamination by inclusions due to the oxidation of the electrode by atmospheric oxygen, the passage of de-oxidants from slag to metal, etc.…”

“…Nitrogen ion implantation is the most widely used method for the modification of steels (Byeli et al 1995;Bull et al 1996;Jones and Bull 1996;Narojczyk et al 2001;Narojczyk et al 2005). Ion implantation with carbon (C) is also quite popular (Yan et al 1998;Sánchez et al 2002).…”

This study explored the effects of nitrogen (N) ion implantation of drills for wood-based materials. Modification of a tool's surface is a common process of prolonging its lifetime. For the purpose of this study, ion implantation was used for modification of drills commonly used in the furniture industry. The rake face of high-speed steel drills was implanted with different doses of nitrogen ions. Durability tests were conducted with the use of a computerized numerical control woodworking machine used for drilling laminated particleboards. The cutting force and drilling torque were measured. The obtained results were presented as wear curves of the examined drill bits. Based on the results, tools implanted with nitrogen ions at different doses had a longer tool life.

“…There are investigations aimed at improvement thereof and expansion of their applications [2]. Nitrogen implantation is used for improvement of the mechanical properties of steel [3][4][5][6], aluminium [7], Ti6Al4V alloy [8] etc. Nitrogen implantation is also applied for improvement of the mechanical properties of sensitive elements in mechanical structures.…”

The effect of nitrogen ion implantation on Stellite 6 cobalt alloy was investigated. In this research, cobalt alloy was implanted with 65 keV nitrogen ions at the fluence of (1 ÷ 10) × 10 16 N + /cm 2 . The distribution of implanted nitrogen ions and vacancies produced by them was calculated using the SRIM program. The surface morphology was examined and the elemental analysis was performed using scanning electron microscopy, energy dispersive X-ray spectroscopy and grazing incidence X-ray diffraction. The wear tests were conducted with the use of the pin-on-disc method. The results demonstrate that implantation with nitrogen ions significantly reduces the friction factor and wear. The friction coefficient of the implanted sample at the fluence of 1 × 10 17 N + /cm 2 increased to the values characteristic of an unimplanted sample after 5000 measurement cycles. The depth of the worn trace was about 2.0 µm. This implies that the thickness of the layer modified by the implantation process is ≈ 2.0 µm and exceeds the initial range of the implanted ions by an order of magnitude. This is referred to as a long-range implantation effect. The investigations have shown that the long-range effect is caused by movement of not only implanted nitrogen atoms but also carbon dopant atoms towards the friction zone. Diffusion of carbon atoms has been documented here for the first time. Furthermore, the increased content of oxygen atoms on the track bottom indicates a dominant oxidative wear of the Stellite samples after nitrogen implantation with the energy 65 keV and the fluences of 5 × 10 16 and 10
