“…Among them, the sliding velocity and the normal load are the two important factors that play a significant role in the variation of tribological behaviour of materials under study [21,22]. Yan et al [23] investigated the wear behaviour of co-continuous Al-23Si/SiC composites, which were performed within a load range of 5-25 N and a sliding velocity range of 100-200 r/min.…”

Abstract:The effects of 0, 0.3, 0.6 and 0.9 wt % modifier La on the dry sliding wear behaviours of AlSi5Cu1Mg alloy were investigated under different friction conditions (normal loads, sliding velocities) by using pin-on-disc configuration. The microhardness of the alloys was tested, and it was found that the microhardness of the alloys was improved by the La addition. The AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the smallest grain size and maximum microhardness. The wear mechanism analysis of the worn surface was done, which drew support from a scanning electron microscope (SEM) that was equipped with an energy dispersive spectrometer. The results showed that AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the best wear resistance, which was mainly due to the modified grain and microhardness. At the sliding velocity of 0.19 m/s, the adhesive wear became the main wear mechanism with the increase of the load because of the rupture of the oxide layer on the friction surface. Under the load of 3.8 MPa, the abrasive wear became slight as the sliding velocity increasing, due to the recrystallization phenomenon that happened in the frictional surface.

“…However, they usually exhibit a poor sliding wear and cavitation erosion resistance which may result in material transfer, mechanical mixing and oxidation between sliding bodies and cavitation erosion in machinery such as hydro-turbines, pumps and valves. A possible solution to the above-mentioned wear problems is to coat the austenitic stainless steel parts by a layer of martensitic stainless steel with a good combination of corrosion resistance and high hardness and erosion resistance using laser cladding process [1][2][3][4].…”

The effect of cladding speed on phase constitution and properties of AISI 431 stainless steel laser deposited coatings Hemmati, I.; Ocelik, V.; De Hosson, J. Th. M. Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim. Shorter processing time has given impetus to laser cladding technology and therefore in this research the AISI 431 martensitic stainless steel coatings are laser deposited at high cladding speeds, i.e. up to 117 mm/s. The analysis of phase constitution and functional properties of the coatings are performed by optical microscopy, Scanning Electron Microscopy (SEM), and hardness and sliding wear tests. The outcome of this research shows that an extreme refinement of the solidification structure will influence the phase constitution of the coatings by lowering the M s temperature and hence stabilizing the austenite which results in lower hardness values and increased wear rates. These results confirm that the structural refinement obtained by higher cladding speeds is not helpful for improving the hardness and wear properties of laser deposited martensitic stainless steel coatings.

“…Austenitic stainless steels are extensively used in nuclear reactors, biomedical implants, as well as in component for chemical and food industries [1,2]. In considering the engineering materials, the main problem with austenitic stainless steels is that it has poor wear--resistance yield strength, fracture and impact toughness [3,4].…”

Mechanical Properties of Boronized AISI 316, AISI 1040, AISI 1045 and AISI 4140 Steels

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, the effect of a notch on impact behavior was examined by conducting the Charpy tests on borided and unborided steels. The greatest notch toughness was found for a steel AISI 316 with a microstructure consisting of different C, Ni and Cr chemical composition compared to AISI 1040, 1045 and 4140 steels.
