“…This way, tool performance is enhanced, making this type of coating a very popular choice [15]. In the study carried out by Kainz [21], multilayered CVD coating (TiN/TiBN) was compared to single-layered TiN and TiBN, concluding that performance was better when opting for the multilayered coating.…”

The milling process is one of the most used processes in the manufacturing industry. Milling, as a process, as evolved, with new machines and methods being employed, in order to obtain the best results consistently. Milling tools have also seen quite an evolution, from the uncoated high-speed steel tool, to the now vastly used, coated tools. Information on the use of these coated tools in recent scientific researches was collected. The coatings that are currently being researched are going to be presented, highlighting some novel advances in the nanocomposite and diamond coatings area, as these coatings are seeing a growing use in the industry, with very satisfactory results, with performance and tool-life increase. Wear mechanism of various types of coatings are also a popular topic on recent research, as the cutting behavior of these coated tools provides valuable information on the tool’s-life. Furthermore, analysis of these mechanisms enables for the selection of the best coating type for the correct application. Recently, the employment of coated tools paired with sustainable lubrication methods as seen some use. As this presents the opportunity to enhance the coated tool’s and the process’s performance, obtaining better results, in terms of better tool-life and better surface finish quality, in a more sustainable fashion.

“…In addition, Vickers hardness of the coated specimens increased gradually with increasing SiC NWs content from 0 to 10 wt%. [22][23][24] It can be seen from Table 1 Figure 8 is the fracture toughness of the coatings with different SiC NWs contents. Therefore, it is determined that the coating with the SiC NWs content of 10 wt% provided the best protection for porous Si 3 N 4 ceramic against mechanical damage.…”

“…The elastic modulus and hardness represent the ability to resist plastic deformation, which is usually expressed by the rate of "H 3 /E 2 ". [22][23][24] It can be seen from Table 1 Figure 8 is the fracture toughness of the coatings with different SiC NWs contents. It is found that fracture toughness of the coating without SiC NWs was very low, which was only 2.8 ± 0.05 MPa m 1/2 .…”

A dense SiC nanowires-toughened α-Si 3 N 4 coating was prepared using a two-step technique for protecting porous Si 3 N 4 ceramic against mechanical damage, and effect of SiC nanowires content on microstructures and properties of the coating were investigated. XRD, SEM and TEM analysis results revealed that as-prepared coatings consisted of α-Si 3 N 4 , O'-Sialon, SiC nanowires and Y-Al-Si-O-N glass phase.

“…Different surface coating methods have been studied as means of additional modification of their properties mostly in the direction of enhanced wear and corrosion behavior. Studies have shown coatings of titanium nitride (TiN) [1], titanium carbide (TiC) [2], titanium carbonitride (TiCN) [3], titanium boron nitride (TiBN) [4], and titanium aluminum nitride (TiAlN) [5] can provide significant improvements to the cemented carbides' behavior in exploitation of the wide range of applications, such as cutting tools [6,7], biomedical implants [8][9][10], and jet nozzles [11,12]. These coatings are mostly deposited using one of three techniques: chemical vapor deposition (CVD), physical vapor deposition (PVD), and plasma-assisted chemical vapor deposition (PACVD) process [13].…”

Analysis of Different Complex Multilayer PACVD Coatings on Nanostructured WC-Co Cemented Carbide

The development of cemented carbides nowadays is aimed at the application and sintering of ultrafine and nano-sized powders for the production of a variety of components where excellent mechanical properties and high wear resistance are required for use in high temperature and corrosive environment conditions. The most efficient way of increasing the tribological properties along with achieving high corrosion resistance is coating. Using surface processes (modification and/or coating), it is possible to form a surface layer/base material system with properties that can meet modern expectations with acceptable production costs. Three coating systems were developed on WC cemented carbides substrate with the addition of 10 wt.% Co using the plasma-assisted chemical vapor deposition (PACVD) method: single-layer TiN coating, harder multilayer gradient TiCN coating composed of TiN and TiCN layers, and the hardest multilayer TiBN coating composed of TiN and TiB2. Physical and mechanical properties of coated and uncoated samples were investigated by means of quantitative depth profile (QDP) analysis, nanoindentation, surface layer characterization (XRD analysis), and coating adhesion evaluation using the scratch test. The results confirm the possibility of obtaining nanostructured cemented carbides of homogeneous structure without structural defects such as eta phase or unbound carbon providing increase in hardness and fracture toughness. The lowest adhesion was detected for the single-layer TiN coating, while coatings with a complex architecture (TiCN, TiBN) showed improved adhesion.
