“…As mentioned above, the duplex treatment also improves other properties, such as wear resistance and toughness. The values obtained in the wear tests are similar to those reported in other studies that evaluated the performance of hard coatings deposited on tool steels [49,53,67], and the CPR values, which are related to the toughness of the coating, are similar and even higher than those reported in references [53,61,66].…”

“…Different studies showed that the nitrides and carbonitrides formed during the nitriding process contribute to the improvement of the wear resistance [72,73]. These wear coefficient results are similar to those reported in reference [53], ranging between 0.23 × 10 −6 and 9.5 × 10 −6 mm 3 /Nm for NiCrN coatings deposited on M2 tool steel, reference [67], showing values of 3.7624 × 10 −15 m 3 /Nm, and reference [49], with values of around 12 × 10 −16 -400 × 10 −16 m 3 /Nm. On the other hand, lower wear coefficient values were reported in [66,74], with wear coefficient values of around 2.5 × 10 −7 m 3 /Nm for Cr/CrN/CrTiN and AlCrN coatings deposited on tool steels, respectively.…”

“…Many other studies showed Lc2 values from 50 N to 80 N for duplex (nitriding + PVD) hard coatings deposited on tool steels [1,[68][69][70]. Furthermore, the values obtained in this study are similar, and even higher in some cases, to those reported for novel PVD techniques such as hybrid PVD [25,71] and closed-field unbalanced magnetron sputtering ion plating (CFUMSIP) [53,61], which presented adhesion strength values up to 116 N and 143 N, respectively. These values can even be compared with those obtained in studies using carbides as substrates, such as [22,23], that showed Lc2 values of approximately 100 N. Finally, it can be said that these results show how this duplex treatment improves the adhesion properties of the conventional PVD magnetron sputtering techniques, making them capable of competing with other types of techniques that to date they have not been able to compete with.…”

“…Furthermore, the toughness of the duplex-treated Vanadis 4 sample was even greater than the 1.2379 duplex's, with a CPR value of 2928 N 2 . These values indicate the great capacity of the coatings to resist crack propagation, and are higher than those reported in [53], which reported CPR values of approximately 1468 N 2 for NiCrN coatings deposited on M2 tool steel, and in [66], which showed CPR values of around 1900 N 2 for AlCrN coatings deposited on HS6-5-2 steel. However, similar results were reported in [61], with CPR values between 1500 and 4300 N 2 depending on the Ni content of the CrAlNiN coatings deposited onto AISI M2 high-speed tool steel substrates.…”

“…The use of duplex PVD coatings for improving the adhesion of hard coatings has been reported in many studies [48][49][50][51]. Other novel techniques, such as HiPIMS with positive pulses [52] and closed-field unbalanced magnetron sputtering ion plating (CFUMSIP) [53], have also been used to improve the adhesion of PVD coatings in steel substrates. As reported in [49,50], duplex treatments based on plasma nitriding and magnetron sputtering showed critical scratch loads (Lc3) of about 60 N and 50 N, respectively.…”

Improved Adhesion and Tribological Properties of AlTiN-TiSiN Coatings Deposited by DCMS and HiPIMS on Nitrided Tool Steels

Hard coatings, such as AlTiN-TiSiN, deposited by Physical Vapor Deposition (PVD) techniques are widely used in industrial applications to protect and increase the lifetime of industrial components, such as cutting tools, dies, and forming tools. Despite their great properties, such as high hardness and wear and oxidation resistance, they are limited in cases of severe conditions due to the poor adhesion between the coating and the substrate. Duplex treatments have commonly been used to improve the adhesive properties of PVD coatings, especially those of the cathodic arc evaporation type. The purpose of this study is to achieve coatings with the good properties of the Magnetron Sputtering processes but with higher adhesion than that achieved with these techniques, thus achieving coatings that can be used under the most severe conditions. In this work, an AlTiN-TiSiN coating was deposited by a combination of DC Magnetron Sputtering (DCMS) and High-Power Impulse Magnetron Sputtering (HiPIMS) after a gas nitriding pretreatment on 1.2379 and Vanadis 4 tool steels. Mechanical (ultra-microhardness and scratch tests) and tribological tests were carried out to study the improvement in the properties of the coating. Duplex-treated samples showed improved adhesion between the coating and the substrate, with second critical load (Lc2) values greater than 100 N. Furthermore, they showed great toughness and wear resistance. These results show that this type of coating technique could be used in the most extreme applications and that they can compete with other techniques and coatings that to date they have not been able to compete with.

Diamond-like carbon lms with Ti dopant (Ti-DLC) are synthesized by reactive magnetron sputtering using a pure Ti metal target. This study determines the effect of methane ow ratios [R m =CH 4 /(Ar + CH 4 ), ranging from 4 to 12%] on the surface morphology, microstructure, mechanical properties and cermet cutting tool inserts features of Ti-DLC lms. The GIXRD diffraction spectrum for Ti-DLC lm depicts an amorphous structure. There are peaks for nano-crystalline TiC at 2θ values of 35.88 o , 41.52 o and 60.14 o , which respectively correspond to the (111), ( 200) and ( 220) planes of the face centered cubic structure.The characteristic binding energy of C 1s, Ti 2p and O 1s for Ti-DLC lm is determined using a highresolution XPS spectra. Increasing R m ow ratio (reducing Ti metal doping) increases the intensity of the Raman spectrum because there is an increased sp 2 -C (sp 2 /sp 3 ratio) site fraction for DLC components. The experimental results show that the hardness of the DLC lm increases from 11.07 GPa to 14.76 GPa as the R m ow ratio is increased from 4% to 12%. The adhesive strength of the Ti-DLC lm coating is measured using a scratch test and shows that the lm adheres well to the substrate. The Ti-DLC lms are coated onto cutter inserts for the dry milling of an Inconel 718 workpiece and the results show that all coated tools have a signi cantly longer tool life than uncoated tools.
