Hardmetals (or cemented carbides) were invented a hundred years ago and became one of the most important materials in engineering. The unique conjunction of fracture toughness, abrasion resistance and hardness makes WC-Co cemented carbides irreplaceable for numerous applications. As a rule, the WC crystallites in the sintered WC-Co hardmetals are perfectly faceted and possess a truncated trigonal prism shape. However, the so-called faceting–roughening phase transition can force the flat (faceted) surfaces or interfaces to become curved. In this review, we analyze how different factors can influence the (faceted) shape of WC crystallites in the cemented carbides. Among these factors are the modification of fabrication parameters of usual WC-Co cemented carbides; alloying of conventional cobalt binder using various metals; alloying of cobalt binder using nitrides, borides, carbides, silicides, oxides; and substitution of cobalt with other binders, including high entropy alloys (HEAs). The faceting–roughening phase transition of WC/binder interfaces and its influence on the properties of cemented carbides is also discussed. In particular, the increase in the hardness and fracture toughness of cemented carbides correlates with transition of WC crystallites from a faceted to a rounded shape.

“…As it needs to be in a high-strength, complex working environment, subject to varying loads and high assembly stresses, as well as high requirements for the resistance of wear, the phenomenon of wear on metallic materials occurs frequently during the long-term work process, which in turn affects the surface quality and accuracy of the parts, and triggered the deterioration of the material surface microstructure, the service life of stainless steel parts and service range with serious consequences [4,5]. Therefore, it is crucial for the sustainable development to study the friction and wear mechanism of materials to minimize the mechanical failure and material damage [6][7][8][9].…”

In order to reveal the nanoscale friction behaviour and wear mechanism of 304 stainless steel during nano particles sliding, this study investigated the effects of sliding velocity and depth on the surface morphology, temperature, mechanical forces, coefficient of friction and sub-surface damage (SSD) of stainless steel by employing molecular dynamics simulations. The results demonstrate that the atoms symmetrically stack on both sides of the sliding grooves during the sliding process. Sliding friction, friction coefficient, defective atoms, phase changing degree and the length of dislocation line increases as the indentation depth of the abrasives, while sliding velocity had little impact on them. Temperature in sliding area and the squeezing effect distinctly increases with the indentation depth the abrasives, which leads more serious damage on the surface of workpiece. The damage layer with a sliding depth of 20 Å can reach about 57.2 Å at a sliding velocity of 100m/s, and it has a maximum value of 41.1 Å at a sliding distance of 50 Å. However, increasing sliding velocity can decline the surface SSD layer, which was at a sliding depth of 20 Å. The microscopic atoms evolution presented in the study uncovers the nano-sliding wear mechanism of stainless steel.

“…In recent years, with the vigorous development of the machining field, the superior performance of stainless steel-based metal materials can be reflected, which has been widely used in aerospace, biomedical and architectural applications, such as austenitic, martensitic, ferritic, etc [1][2][3][4]. Friction and wear have been an urgent challenge for the industry, the main cause of which is the failure of core components due to material depletion, which seriously affects their service life and economic costs [5][6][7]. At present, scientists have made great progress in anti-friction and wear reducing materials, surface coatings, lubricants and additives [8][9][10][11][12][13][14], relatively speaking, the textured surface technology is gradually becoming the focus of attention due to its excellent tribological properties.…”

In order to reveal the friction behaviour and wear mechanism of nanoscale textures on the friction pair of 304 stainless steel, molecular dynamics simulations were firstly used to investigate the effects of smooth and textured surfaces on the tribological properties of the stainless steel substrate, and then focus on the effects of sliding velocity and depth on the surface morphology, mechanical force, friction coefficient, anisotropy, stress, temperature and dislocations of the textured substrate. The results show that the temperature, friction, stress, and dislocation line length of the textured surface are relatively smaller than those of the non-textured surface, and the textured surface has a smaller and more stable friction factor, which ultimately leads to a reduction of the friction factor by about 0.090. When the sliding distance is 120 Å, the number of defective atoms in the textured substrate is reduced by 12.9%, and its anisotropy is more stable. At the same indentation depth, the average friction coefficient, temperature and anisotropy increase significantly with increasing sliding velocity. The average friction coefficient is maximum when the sliding velocity is increased to 400 m s−1, with a value of about 0.833. The sliding friction, friction coefficient, dislocation line length, number of defect atoms, number of stacked atoms, stress, temperature and anisotropy factor increase with increasing depth of abrasive indentation. The average friction coefficient is minimum at a sliding depth of 4 Å, with a value of about 0.556, and the number of defective atoms is reduced by 83.2%. This indicates that textured surface treatment of 304 stainless steel and selection of appropriate sliding parameters can effectively reduce the wear during the friction process and improve the wear resistance of the substrate.
