“…Hard TiN coatings did not improve tool galling properties when in contact with stainless steel. Rodríguez-Baracaldo et al used the ball-on-disc test to investigate the load capacity of physical vapor deposition (PVD) (Ti 0.7 Al 0.3 )N coating on gas nitride AISI H13 steel and the results showed that the duplex coating system provided higher load capacity than the single-layered system did [53]. Özgür et al tested five different PVD film coatings (TiN, TiAlN, CrN, AlTiN and TiCN) on M41 steel to investigate their thermal diffusivities and wear performance [54].…”

Abstract:The tribo-characteristics of metal forming at high temperatures have not yet been well understood due to the complex nature of thermal, microstructural, interaction, and process parameters. This is a review paper on the effects of temperature, coating, and lubrication to the tribological characteristics in hot forming as well as the tribometers for different metal forming processes at elevated temperatures mainly based on the experimental work. The tribological behaviors of oxides in hot forming, such as rolling and stamping, were reviewed and presented. Some commonly used surface coatings and lubricants in hot forming were given. Many types of tribometer were selected and presented and some of them provided a great potential to characterize friction and wear at elevated temperatures. Nevertheless, more testing conditions should be further investigated by developing new tribometers. Eventually, experimental results obtained from reliable tribometers could be used in theory and model developments for different forming processes and materials at high temperatures. The review also showed the great potential in further investigations and innovation in tribology.

“…Studies aimed to analyze the thermal stability of the substrate/coating system, wherein the substrate before the deposition of the coating is subjected to a process of nitriding, are also taken into account [20]. In the paper [21] is described the test for wear resistance of TiAlN (Ti 0.7 Al 0.3 ) coatings deposited on the nitrided stainless steel and non-nitrided H13 steel, using ball-on-disc method at room temperature and at 600°C. It was observed that in the room temperature there are not significant differences in wear rate, but they were revealed clearly at the temperature of 600°C, in which nitrided steel/PVD coating system has considerably better properties than the non-nitrided steel/PVD coating system.…”

The aim of the research was to investigate the influence of nitriding of the substrate made of 42CrMo4 steel on thermal stability of the antiwear CrCN coating deposited on its surface using Cathodic Arc Evaporation method. Samples of non-nitrided and nitrided substrate/CrCN coating systems were tested with Modulated Temperature Thermodilatometry, which program included system annealing in 26 h, temperature of 290°C and argon atmosphere. Recorded during tests, changes in substrate elongation in response for changes of sample temperature, enabled qualitative determination of changes in stress states in the coatings as a result of samples annealing. Annealing of the system with nitrided substrate resulted in smaller change in residual stress in coating than for the system with non-nitrided substrate, which can indicate its better thermal stability. Values of residual stresses in coatings calculated by sin 2 ψ method before and after annealing on the basis of tests performed using X-Ray diffraction, agree with results of dilatometric tests.

“…Studies show that the coatings on harder substrate have better wear resistance than those on softer substrate [8,9]. So as to obtain hard substrate, researchers applied nitriding process on substrate surfaces and they tried to use diusion zone as substrate in coating process [5,10,11]. In fact, studies showed that with nitriding process, load carrying capability of the coating/substrate was developed and chemical stability of dies against aluminum was enhanced [4,10].…”

The aim of this study is to compare the wear behavior of X45MoCrV5-3-1 tool steel, used as die material in aluminum extrusion, after single treatment (CrN coating) and duplex treatment (nitriding and CrN coating). Gas nitriding and physical vapor deposition were used as processing techniques and wear tests were carried out at both room and elevated temperatures. A ball-on-disc type tribometer was used for room temperature tests, utilizing Al2O3 ball as counterpart. In order to simulate the wear conditions during extrusion, hot wear tests were carried out at 450• C using block-on-cylinder type tribometer against AA 6080 material. Worn surfaces were studied by microscopy to reveal the wear characteristics of treated steels. It was found that (i) duplex treated steel, having higher friction coecient at room and elevated temperature, had higher wear resistance, (ii) at room temperature single treated steel exhibited higher volume loss than the duplex treated one, (iii) at elevated temperature duplex treated steel revealed a stable coating layer, whereas micro cracks were observed on the surface of the single treated steel.
