“…A new slider type of test system has been developed to study the performance of several alternative die materials sliding against the advanced HSS [7] and to evaluate the performance of several kinds of coatings and lubricants [8]. Twist compression test (TCT) [9], ball-on-disk test [10], SOFS tribometer (disc-shaped tools sliding against a teal sheet surface) test [11] and deep drawing test [12], ironing test [13], a tensile strip test [14] have been used to investigate the galling in forming the HSS. However, all of the experiments mentioned above are performed at the room temperature.…”

In order to investigate the friction and wear behavior of high strength steel in hot stamping process, a hot strip drawing tribo-simulator is developed and the friction coefficient, which is an important parameter in the finite element modeling, is measured. The results have shown that the friction coefficient remains almost unchanged until temperature reaches 500°C. It then increases sharply as temperature is increased from 500 to 600°C. It has also been shown that the friction coefficient decreases as the drawing speed increases. The change in the dominate wear mechanism as the temperature and the drawing speed increases has been identified from SEM analyses of the worn surface. The dominate wear mechanism is the groove cutting at temperatures between room temperature and 500°C, which changes to the adhesive wear at temperatures above 500°C. The main wear mechanism is the adhesive wear at 25 mm/s, which changes to the slight groove cutting at 75 mm/s.

“…The galling phenomenon is sensitive to many factors such as microstructure and properties of the contacting surfaces, roughness, temperature, the chemical composition in the interface between surfaces, etc. [6,7,15,27,28]. In the present work, it was found to be of high importance to eliminate factors that affect the transfer of material between contacting surfaces such as lubrication and roughness.…”

In the present study, Uddeholm Vancron SuperClean cold work tool steel was investigated concerning wear resistance and fatigue strength, using laboratory and semi-industrial tests. The Uddeholm Vancron SuperClean was designed with the help of ThermoCalc calculations to contain a high amount of a carbonitride phase, which was suggested to improve tribological performance of this tool steel. In order to investigate the tested steel, galling tests with a slider-on flat-surface tribotester and semi-industrial punching tests were performed on an advanced high-strength steel, CP1180HD. Uddeholm Vanadis 8 SuperClean containing only a carbide phase and Uddeholm Vancron 40 containing a mixture of carbides and carbonitrides were also tested to compare the performance of the tool steels. The microstructure and wear mechanisms were characterized with scanning electron microscopy. It was found that the carbonitrides presented in Uddeholm Vancron SuperClean improved its resistance to material transfer and galling. Semi-industrial punching tests also confirmed that Uddeholm Vancron SuperClean cold work tool steel also possesses enhanced resistance to chipping and fatigue crack nucleation, which confirms the beneficial role of the carbonitride phase in wear resistance of cold work tool steel.

Camera components made of stainless steel (SS304) and Ti-6Al-4V alloy are used as anti-vibrator stoppers (pin-pull) for the focusing imaging system embedded in satellites that are remotely operated. Vibration tests for the certification China-Brazil Earth Resources Satellite 3 (CBERS-3) generated galling problems in some parts of these components. Nitrogen plasma immersion ion implantation (N-PIII) was an useful technique to enhance the surface properties of these components and consequently to overcome such problems. This work shows the characterization of implanted SS304 samples to explain the surface modifications that allow the improving of the mentioned components. X-ray diffraction (XRD) analysis of the samples indicated that N-PIII at 12 kV form expanded austenite phase with 0.7 micrometers of thickness and atomic force microscopy (AFM) showed a typical nodular morphology at the surface. Hardness measurements revealed a significant increase in the surface hardness after N-PIII treatment. Wear tests using a pin-on-disc device showed an increase in wear resistance and a reduction in the friction coefficient. Such observed surface modifications successfully prevented galling in the pin-pull camera parts through the reduction of the adhesive mechanisms.
