“…Cemented carbides have been widely used as cutting tools in machining fields (turning, milling, and drilling) due to their excellent mechanical properties, such as high hardness, high wear resistance, and high strength [1][2][3][4]. However, in the metal cutting process, particularly in the dry cutting process, the working temperature increase due to severe friction between the cutting tool and workpiece, resulting in serious tool wear and a shorter tool life [5,6]. As a result, it is critical to reduce friction and extend the life of cutting tools, particularly in high-temperature environments.…”

Linear textures and AlCrN coatings were produced on cemented carbides using laser and physical vapor deposition, respectively. Reciprocal sliding friction studies were conducted under dry friction conditions to examine the tribological properties of the AlCrN coatings placed on textured surfaces against Si3N4 ceramic balls at various temperatures. The findings demonstrated that at friction temperatures of 200 °C, 400 °C, and 600 °C, the average friction coefficient of the AlCrN coating samples placed on textured surfaces was lower than that of the samples deposited on smooth surfaces. This reduction occurred by 9.6%, 15.1%, and 23.9%, respectively. Meanwhile, because micro-textures trap wear debris, AlCrN coating samples put on textured surfaces had lower surface adhesions, indicating that micro-textures can improve the tribological properties of AlCrN coatings. Finally, the mechanisms of micro-texture improving tribological properties were investigated. Micro-textures can store wear debris, reducing friction coefficients and thereby minimizing abrasive wear. Micro-textures, on the other hand, can prevent coating oxidation by lowering the temperature of the friction area, resulting in less oxidative wear.

“…Due to the development of the furniture industry, the demand for new tool materials has increased in recent years, providing increasingly higher machining parameters and improved performance. The researchers’ works are focused mainly on improving the cutting and strength properties of WC-Co carbides, by: hard coating, ion implantation or development of new composite materials based on WC-Co [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Despite all efforts of materials engineering, the “ideal tool material” has not yet been developed.…”

The paper presents the effect of diamond particle size (varying between 2.5 µm and 20 µm) on the microstructure, density and hardness of WC-Co/diamond composites. The obtained materials contained 30% vol. diamond. The advanced sintering method Pulse Plasma Sintering (PPS) was used for the production of composites. The sintering process was carried out in two stages at a pressure of 50 and 100 MPa and a temperature of 1050 °C. Depending on the size of the diamond particles, composites with a density of 91–99% were obtained. Microstructure studies were performed employing scanning electron microscopy, along with an analysis of the chemical composition in micro-areas. Additionally, the phase composition was investigated by means of X-ray diffraction. In addition, hardness tests were performed. It was found that the size of the diamond particles significantly influenced the microstructure of the tested materials, as well as the density and hardness. As a result of PPS sintering of composites containing the finest diamond particles (2.5–5 µm), the presence of a metastable type of diamond—graphite was found.

“…Improving the results of the cutting process can be implemented in several ways, mainly by changing the main parameters of the cutting process (e.g., velocity and feed) [1,2] or improving the tool design [3][4][5]. However, the most significant positive results can be achieved using the tool and structural materials from wear-resistant coatings with high physical, mechanical and chemical properties [6,7].…”

This article deals with improving the wear resistance of multilayer coatings as a fundamental problem in metal surface treatment, strengthening elements of cutting tools, and ensuring the reliability of machine parts. It aims to evaluate the wear depth for multilayer coatings by the mass loss distribution in layers. The article’s primary purpose is to develop a mathematical method for assessing the value of wear for multilayer steel-based coatings. The study material is a multilayer coating applied to steel DIN C80W1. The research was performed using up-to-date laboratory equipment. Nitrogenchroming has been realized under overpressure in two successive stages: nitriding for 36 h at temperature 540 °C and chromizing during 4 h at temperature 1050 °C. The complex analysis included several options: X-ray phase analysis, local micro-X-ray spectral analysis, durometric analysis, and determination of wear resistance. These analyses showed that after nitrogenchroming, the three-layer protective coating from Cr23C6, Cr7C3, and Cr2N was formed on the steel surface. Spectral analysis indicated that the maximum amount of chromium 92.2% is in the first layer from Cr23C6. The maximum amount of carbon 8.9% characterizes the layer from Cr7C3. Nitrogen is concentrated mainly in the Cr2N layer, and its maximum amount is 9.4%. Additionally, it was determined that the minimum wear is typical for steel DIN C80W1 after nitrogenchroming. The weight loss of steel samples by 25 mg was obtained. This value differs by 3.6% from the results evaluated analytically using the developed mathematical model of wear of multilayer coatings after complex metallization of steel DIN C80W1. As a result, the impact of the loading mode on the wear intensity of steel was established. As the loading time increases, the friction coefficient of the coated samples decreases. Among the studied samples, plates from steel DIN C80W1 have the lowest friction coefficient after nitrogenchroming. Additionally, a linear dependence of the mass losses on the wearing time was obtained for carbide and nitride coatings. Finally, an increase in loading time leads to an increase in the wear intensity of steels after nitrogenchroming. The achieved scientific results are applicable in developing methods of chemical-thermal treatment, improving the wear resistance of multilayer coatings, and strengthening highly loaded machine parts and cutting tools.
