“…Although the E corr can represent the thermodynamic stability of tool materials under electrochemical corrosion condition, the I corr which represents the kinetics of materials’ corrosion can more exactly reflect the corrosion behavior than the E corr . 11 From the view of I corr , the sequence of corrosion resistance of each tool in artificial seawater was AC405K > YBG302 > NX2525 > YT15. The result indicated that the coatings improved the corrosion resistance of cemented carbide substrate materials, and the cemented carbide tool material had the poor corrosion resistance in artificial seawater.…”

To select the optimum tool material for the cutting of marine high-strength steels using a hole-opening equipment in the marine environment, this article conducted a comparative study on the corrosion property, tribological behavior and cutting performance of cermet, cemented carbide and coated tools. The results reveal that the coated tool materials have good corrosion resistance with coating protection, and poor wear resistance with adhesive and corrosive wear in artificial seawater, and present moderate cutting performance. In addition, the cemented carbide tool materials show poor corrosion resistance and good wear resistance due to the lubrication effect of corrosion products in artificial seawater, but have bad cutting performance with a high flank wear value. Moreover, the cermet tool materials present acceptable corrosion and wear resistance with adhesive and corrosive wear in artificial seawater and have the excellent cutting performance. Taking into account the corrosion resistance, wear resistance and cutting performance of tool materials and regarding cutting performance as an important indicator, the cermet tool materials with superior comprehensive performances are suitable for the cutting of marine high-strength steels in the marine environment.

The paper is dedicated to the life prolongation of the tools designed for deep-hole drilling. Among available methods, an ion implantation process was used to improve the durability of tungsten carbide (WC)-Co guide pads. Nitrogen fluencies of 3 × 1017 cm−2, 4 × 1017 cm−2 and 5 × 1017 cm−2 were applied, and scanning electron microscope (SEM) observations, energy dispersive spectroscopy (EDS) analyses, X-ray photoelectron spectroscopy (XPS) and Secondary Ion Mass Spectrometry (SIMS) measurements were performed for both nonimplanted and implanted tools. The durability tests of nonimplanted and the modified tools were performed in industrial conditions. The durability of implanted guide pads was above 2.5 times greater than nonimplanted ones in the best case, presumably due to the presence of a carbon-rich layer and extremely hard tungsten nitrides. The achieved effect may be attributed to the dissociation of tungsten carbide phase and to the lubrication effect. The latter was due to the presence of pure carbon layer with a thickness of a few dozen nanometers. Notably, this layer was formed at a temperature of 200 °C, much smaller than in previously reported research, which makes the findings even more valuable from economic and environmental perspectives.

“…At present, as technologies of advanced sintering develop, diversified sintering methods concerning cermets have been developed, including vacuum sintering [ 5 , 6 ] and gas pressure sintering [ 7 ]. With the emergence of advanced sintering equipment, more and more studies have been conducted on sintering methods such as microwave sintering [ 8 ], hot-pressing sintering [ 9 , 10 ], high-pressure temperature sintering [ 11 ] and spark plasma sintering (SPS) [ 12 ].…”

In this study, a Ti(C,N)-based cermet material was prepared through vacuum sintering. The research also investigates how holding time and maximum sintering temperature influence the material microstructure and mechanical properties. X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) were used to analyze the composition of the cermet. The microstructure of the cermet was analyzed and examined using a scanning electron microscope (SEM). A Vickers hardness tester was used to test the mechanical properties of the materials. As indicated by testing results, the hardness of the material decreases as the temperature of sintering increases, and its fracture toughness increases gradually as holding time increases. Ti(C,N)-based cermet manifested the optimal mechanical properties when sintering was conducted under 1400 °C with 80 min of holding time. Moreover, the material microstructure is significantly affected by the sintering process. The grain size of Ti(C,N) cermets increases as the sintering temperature increases. The microstructure tends to be uniform and the complete core-rim structures are established as the holding time increases.
