TiCrN-TiAlN-TiAlSiN-TiAlSiCN multi-layers utilized to increase tillage tools useful lifetime

Abstract

For the first time, a hard wear-resistant multi-layer of TiCrN-TiAlN-TiAlSiN-TiAlSiCN was deposited on carbon steel CK45-based tillage tools to increase their useful lifetime. The layers were deposited by using an arc-PVD method without post-annealing procedures. XRD and EDX data indicated that TiCrN, TiAlN, TiAlSiN, and TiAlSiCN formed individually and as a multi-layer of high-quality crystalline layers with mostly cubic structures. The studies on the multi-layers coating morphology, roughness and hardness gave reasonable results as a roughness of 35 nm and a hardness of 32.2 GPa. The coated sweep duck blade tillage tools were tested on the field along with a soil bin to obtain their wear behavior at different traveling distances. The draft force of all blades showed promising results. As the coated layers were worn off, their draft force increased. In comparison with single-layer coatings, the multi-layer structure demonstrated an increase in the useful lifetime of the blades.

High-Voltage, High-Current Electrical Switching Discharge Synthesis of ZnO Nanorods: A New Method toward Rapid and Highly Tunable Synthesis of Oxide Semiconductors in Open Air and Water for Optoelectronic Applications

“…By looking at this pattern, it is clear that the XRD peaks in the samples synthesized in water, more specifically the (002) plane, experience an increase in the intensity compared to the air-synthesized specimens. The crystallite sizes of the ZnO nanorods are calculated using the Debye–Scherrer equation, (τ = K λ/βcosθ, τ stands for crystallite size, K = 0.94 is the Scherrer constant, λ =1.54 Å is the Cu pole’s wavelength, β is the full width at half maximum (FWHM) of the diffraction peak, and θ is the angle of the diffraction peak). The FWHM of the main (101) peak was measured to be 0.43° with the Xpert High Score Plus software.…”

Raman and ultraviolet–visible spectroscopy of titanium chromium nitride thin films

“…Ternary transition metal nitride coatings, such as titanium chromium nitride (TiCrN), share striking optical, magnetic, electronic, catalytic, mechanical, and anti-corrosive characteristics, deemed to be desirable for industrial applications, such as high-speed machining, tooling, optical devices, and magnetic storage devices. Titanium chromium nitride is one of these ceramic materials that has been attracting considerable attention due to its high-temperature oxidation resistance (866 K), low friction coefficient (0.3), high hardness (4000 HV), and high corrosion resistance [1][2][3][4].…”

Improvement of the Physical and Mechanical Properties of the Cutting Tool by Applying Wear-resistant Coatings Based on Ti, Al, Si, and N

“…The diffraction peaks of TiAlN coating are shifted to higher diffraction angles compared to stoichiometric TiN, which indicates a decrease in the lattice parameter (0.418 nm compared to 0.424 for pure TiN) [24][25].…”

“…Due to this, nanocomposite coatings based on Ti, A, Si, and N are now increasingly used for cutting tools. Compared to traditional durable TiN, AlN, or TiAlN coatings, the TiAlSiN coating, which forms the structure of the amorphous Si3N4 shell for the TiAlN nanocrystalline coating, has attracted worldwide attention due to its enhanced properties as a complex coating for multilayer coatings and multicars [3,6,20,[24][25][26][27][28][29].…”

“…It is well known that hardness increases with decreasing grain size, which can be explained by an increase in areas of grain boundaries that interfere with dislocation movements in the form of dislocation accumulations (Hall-Patch effect) [24][25].…”
