The Effect of TiN, TiAlN, TiCN Thin Films Obtained by Reactive Magnetron Sputtering Method on the Wear Behavior of Ti6Al4V Alloy: A Comparative Study

Abstract

Titanium-based alloys have gained worldwide application over the past century. However, their low wear resistance remains an unresolved challenge for the Ti6Al4V alloy, which has significant industrial use. Therefore, it is an integral part in material selection and surface treatment in friction-wear applications. Tribological properties are not only material parameters but also system parameters where test conditions are essential. Hardness, roughness and contact conditions of coatings, which are especially important in surface treatments, affect wear modes. In this study, titanium nitride, titanium aluminum nitride and titanium carbon nitride coatings were obtained by unbalanced reactive magnetron sputtering to improve the weak tribological properties of Ti6Al4V alloy. The wear behavior was studied at room temperature in dry conditions. Wear tests were conducted under different loads and different sliding rates, which were followed by comparative analyses of their wear resistances. While the coated samples showed higher wear resistance than the uncoated Ti6Al4V alloy, the lowest wear track width was observed in TiN coating. Depending on the surface properties of the coatings, adhesion, abrasion and oxidation wear mechanisms were observed. It was concluded that a TiN coating could be a material of choice for applications where triple abrasive wear is dominant.

Improvising CODAS method functionalized with grey numbers to improve the performance of PVD titanium carbon nitride (TiCN) thin film coating: a novel approach

“…Titanium carbo nitride (TiCN) belongs to the transition metal nitride family and is basically a ternary carbo nitride group that is capable of providing a combination of the characteristics of titanium nitride (TiN) and also titanium carbide (TiC), like enhanced hardness, better thermal stability, improved wear, higher corrosion resistance, reduced oxidation, and many more [1][2][3]. The addition of carbon in the TiN matrix creates an amorphous carbon phase, resulting in the enhancement of grain boundary length, which leads to the coating offering higher corrosion resistance.…”

Surface Enhancement of Titanium-Based Coatings on Commercial Hard Steel Cutting Tools

“…X-ray diffraction spectroscopy was employed to extensively investigate the cr line phases of the coated samples. The raw steel substrate exhibited three distinc phases on the (110), (200), and (211) reflection planes, which also appear in the n coatings due to the X-ray penetration depth exceeding the coating thickness [42-4 accordance with its FCC phase, the TiN coating primarily exhibited strong diffr peaks at 36.6 and 42.6°, corresponding to the (111) and ( 200) planes [45,46]. Weak pe 73.8 and 77.6° can be attributed to the (311) and (222) planes, respectively, as confirm previous studies [47][48][49].…”

Laser Shock Peening: Fundamentals and Mechanisms of Metallic Material Wear Resistance Improvement

“…By virtue of its usefulness in the creation of parts with complex geometries, AM has recently gained a lot of attention [52]. Additively manufactured parts typically consist of multiple layers of stacked molten metal, whose surfaces are prone to cracking and wear [53]. Consequently, wear resistance tends to be low in AM metals.…”
