“…Nevertheless, it is difficult to conclude if removal of binder or microfracture of WC is the controlling mechanisms when coarse WC-Co grade is worn by fine abrasive. Even though binder removal was evidently observed, a gradual fracture of WC grains, similar to as reported in [15] for erosive wear of WC-Co, is more likely controls wear rates.…”

Abrasive wear of a series of WC-(5-14 wt.%) Co hardmetals was investigated employing P800 and P120 SiC abrasive papers. It was found that if fine abradant was utilized, submicron grades demonstrated substantially higher wear rates than the coarse grades. Such a behaviour was associated to different wear mechanisms operating for fine and coarse grades and correlated to the ratio of the abrasive size to size of the hard WC phase.

“…Therefore, its characterization in a row is essential. [2] The generated wear processes is very complex because it is followed by physicochemical phenomena appearing on the contact surfaces between tool part, workpiece and chip, whereas in the active cutting tool part surface, pressure increases up to 103 to 2x103 MPa and temperature increases from 100°C to 1000°C and even more [3][4][5][6][7][8]. In fact, several wear mechanisms occur simultaneously, although any one of them may dominate the process.…”

Abstract. The machining of superalloy parts still an area not very clear in mechanical manufacturing. It is found to be used in particular areas such as gas turbine, rocket engine, space ships, nuclear reactors, and pumps. The machining of Inconel 738 superalloy has been studied in this context, with the aim to understand the wear behavior with carbide inserts coated with TiN and in order to optimize the cutting parameters before starting the production. The wear behavior of the inserts during the machining process of a very tough austenitic superalloy is unclear, and requires a series of well determined tests. The life of the insert under high stress such as pressure, cutting speed, high temperature, in a hostile zone and in contact with a very tough and harder material is determined. The generated process of wear is very complex, because it is followed by physico-chemical phenomenon appearing on the contact surfaces between the active part of the tool and workpiece.The lifetime of machine tools often depends on the tribological characteristics of the material couples (cutting tool / material to be machined). It has been shown that the most influential parameter is the coating, then comes the sliding speed. A relationship between the wear VB and the roughness Ra is proposed to collect information on the cutting edge and the quality of the tool by measuring the roughness. For wear measurement, an indirect method is used in coupling a Touptek photonics camera to capture and Ttoupview analysis software.

“…A very important group of such materials is represented by the so-called metallo-carbides (or cemented carbides), namely heterogeneous composites WC/M which consist of grains of tungsten carbide glued with a binder metal M to combine the hardness of the carbide with the toughness of the metal; see [5][6][7].…”

We have performed ab initio total energy calculations using the full‐potential linearized augmented plane wave (FP‐LAPW) method with the generalized gradient approximation (GGA) for the exchange–correlation potential to investigate structural, elastic, cohesive, electronic and magnetic properties of the tungsten‐containing perovskite‐like phases W3NiC, W3NiN and Co3WC. The optimized lattice parameters, independent elastic constants (Cij), bulk moduli (B) and shear moduli (G), as well as densities of electronic states and cohesive and formation energies are obtained and analyzed for the first time.
