“…Nitrocarburizing is a thermochemical treatment applied mainly to iron alloys to improve fatigue strength, wear resistance, and corrosion resistance [1,2]. These improvements are attained by the diffusion of nitrogen and carbon beneath the surface, the formation of a compact compound layer (iron carbonitrides), and the formation of a thick diffusion zone, i.e., a region where the matrix nitrogen and carbon solubility limit is not exceeded.…”

“…The use of ion beam allows a fine control of the ion energy of the involved species, ion flux, and proportion of the species arriving at the substrate. The specific purpose of this work was two-fold: (1) to analyze the effects on the microstructure of the amount of carbon at the surface sample during the ion beam nitriding, and (2) to find the proper conditions leading to the formation of a  monophase compound nitride layer.…”

The nitrocarburization of the AISI-H13 tool steel by ion beam assisted deposition is reported. In this technique, a carbon film is continuously deposited over the sample by the ion beam sputtering of a carbon target while a second ion source is used to bombard the sample with low energy nitrogen ions. The results show that the presence of carbon has an important impact on the crystalline and microstructural properties of the material without modification of the case depth.

“…This wear mechanism possesses the characteristics of typical adhesive wear. Adhesive wear occurs when the contact pressure between rolling surfaces is high enough to cause local plastic deformation and welding between the contacting asperities [33], whereas the crystalline Ti-based alloy exhibited less adhesive wear on the surface. The Ti-based BMG and the matrix with 12 vol.…”

“…% CNTs exhibited an abrasive wear track. Abrasive wear occurs when hard debris particles are indented and form a groove on the rolling surface of the material [33]. Energy-dispersive X-ray spectroscopy (EDS) analysis of the wear tracks indicated that the dark areas of the JIS SKS3 tool steel were rich in Fe, suggesting that material transfer occurred from the soft counterpart rolling to the hard Ti-based BMG composites.…”

Abstract:The present paper reports the preparation and wear behavior of mechanically alloyed Ti-based bulk metallic glass composites containing carbon nanotube (CNT) particles. The differential scanning calorimeter results show that the thermal stability of the amorphous matrix is affected by the presence of CNT particles. Changes in glass transition temperature (T g ) and crystallization temperature (T x ) suggest that deviations in the chemical composition of the amorphous matrix occurred because of a partial dissolution of the CNT species into the amorphous phase. Although the hardness of CNT/Ti 50 Cu 28 Ni 15 Sn 7 bulk metallic glass composites is increased with the addition of CNT particles, the wear resistance of such composites is not directly proportional to their hardness, and does not follow the standard wear law. A worn surface under a high applied load shows that the 12 vol. % CNT/Ti 50 Cu 28 Ni 15 Sn 7 bulk metallic glass composite suffers severe wear compared with monolithic Ti 50 Cu 28 Ni 15 Sn 7 bulk metallic glass.

In this study we examined the influence of nitrocarburizing holding time on the surface microstructures and erosion behavior of JIS SKD11 modified cold-work tool steel (DC11 tool steel). The steel was nitrocarburized at 570°C for varying durations of 1, 3, and 5 h. The microstructures and hardness of the nitrocarburized coatings were then analyzed. Particle erosion was examined at different impinging angles (15-90°) and impact speeds (20.2-45.6 m/s).The results show that a single diffusion zone is formed on the specimens at 1 h nitrocarburizing while a compound layer together with diffusion zone are formed on the specimens for the nitrocarburizing time beyond 3 h. In addition, the compound layer formed on the specimens exhibits a higher erosion resistance. The nitrocarburizing treatment not only increases the surface hardness but also improves the erosion resistance of the experimental steel. This improvement in erosion rates is more obvious at higher impact speeds and lower impinging angles. The maximum erosion rate appears at an impinging angle of 30°for all specimens. In this condition, plough grooves and cutting lips appear in the eroded surface; however, the erosion tracks are more superficial for nitrocarburized specimens than untreated specimen. The exponent in the power law E˙ϭkV n varied between 1.9-2.3 for impinging angles between 15°and 90°.KEY WORDS: tool steel; nitrocarburizing; erosion; surface structure; microhardness.cal composition, analyzed using a glow-discharge optical emission spectroscope (GDOS), is shown in Table 1. Square specimens of size 50 mmϫ35 mmϫ10 mm were cut from the plate for erosion tests. A hole with 3-mm diameter was drilled into each specimen, and a steel wire was threaded through it to facilitate loading of the specimens into the salt bath. Before nitrocarburizing treatment, the specimens were ground using #1200 silicon carbide (SiC) paper and subsequently cleaned with acetone and methanol. Finally, they were dried and loaded into the salt bath. Before immersion into the salt bath, the specimens were preheated in an air-circulated furnace at 350°C for 1 h. The nitrocarburizing treatment was carried out at 570°C in a salt bath (mainly containing dissolved potassium and sodium cyanates and a small quantity of carbonate salt) for different durations of 1, 3, and 5 h, followed by slow cooling in air down to ambient temperature. After nitrocarburizing treatment, all the specimens were cleaned ultrasonically in acetone for 15 min. In this study, the untreated specimen and the specimens nitrocarburized for 1, 3, and 5 h were designated as NC-0, NC-1, NC-3, and NC-5, respectively.Nitrided layers were examined using an optical microscope (OM), and X-ray diffraction (XRD) investigations of the nitrided layer were carried out using X-ray diffractometer (XRD-6000) with Cu Ka radiation. Microhardness tests of the specimens were carried out in a Vickers hardness tester, under a small load of 50 g for 15 s. An average hardness value based on six measurements was obtained from representativ...
