“…They are used as bulk material form in a variety of industrial applications such as hot-working dies and tools, propellers, pump impellers, ball bearings and races, bushings, valve seats, industrial knives, where high strength or wear resistance and moderate corrosion resistance are needed [6]. It is well known that the properties obtained of these steels are strongly influenced by the heat treatments.…”

This paper focuses on the tribological characterization of new martensitic stainless steels by two different tribological methods (scratch and dry wear tests) and their comparison to the austenitic standard stainless steel AISI 316L. The scratch test allows obtaining critical loads, scratch friction coefficients, scratch hardness and specific scratch wear rate, and the dry wear test to quantify wear volumes. The damage has been studied by ex situ scanning electron microscopy. Wear resistance was related to the hardness and the microstructure of the studied materials, where martensitic stainless steels exhibit higher scratch wear resistance than the austenitic one, but higher hardness of the martensitic alloys did not give better scratch resistance when comparing with themselves. It has been proved it is possible to evaluate the scratch wear resistance of bulk stainless steels using scratch test. The austenitic material presented lower wear volume than the martensitic ones after the dry wear test due to phase transformation and the hardening during sliding.

“…They also pointed out the influence of FS on the bending, the tensile and the wear characterization. Puli et al [16] explained microstructural transformations in depositing AISI 440C on mild steel by the FS method; these transformations resulted in the transformation from ferrite to austenite and the dissolution of certain amount of carbide during the heating stage. The coatings exhibited a hardness value of approximately 590 HV.…”

“…However, the main objective in multi-layering is to ensure good bonding between successive tracks of the deposited material. Puli et.al [16] established that good inter-track bonding can be achieved only when good frictional contact occurs between the edge of previously deposited track and the rotating mechtrode while depositing the next track. In this The interface between the coating and the substrate in sample 3 having a 3 mm overlap ( Fig.…”

SummaryNowadays friction surfacing (FS) has become a popular solid state surface coating technology suitable for a range of substrates. The technology has the ability to produce coatings with marginal dilution and good metallurgical bonding. The present study has aimed at producing a single-track and a three-track overlapping coatings on high-speed steel substrates using an AISI 316 consumable rod. Microhardness of coatings was examined by a Vickers micro hardness tester. Coatings of all the friction surfaced samples in as-deposited condition showed significant hardness. The infrared thermography showed that the peak temperature achieved by the AISI 316 coating was about 1020 ͦ C. The coatings, thus attained, were further analysed for their microstructural features and interfacial characteristics by using FE-SEM. The EDX analysis showed the presence of nickel, chromium and oxygen, which indicates the formation of oxide compounds. The formation of AISI 316 deposits on the HSS substrate and the effect of coating overlapping are discussed in this article.

“…Improvement in wear resistance of the high-carbon steel by FSP was due to reduced plasticity of the near-surface material during sliding contact. Puli and Janaki Ram [16] reported that a single track of friction-surfaced AISI 440C coating exhibited superior corrosion resistance as compared to the conventional heat-treated sample, but no report on the corrosion behavior of the multi-pass can be found in the literature. On the other hand, the effect of multi-pass FSP on the microstructure and corrosion behavior of pure Ti in 0.5 M H 2 SO 4 solutions was reported by Fattah-Alhosseini [17].…”

In the present study, the influence of multi-pass friction stir processing (FSP) of AISI 420 martensitic stainless steel on the microstructure, hardness, and corrosion behavior was investigated. Similar to single-pass FSPed 420, the multi-pass FSPed specimens with different overlapping ratios incurred microstructural change at the center and retreating side of the second track with martensite, retained austenite, and chromium carbides. Overlapping of the two successive tracks in the multi-pass FSPed 420 led to back-tempering and a local drop in hardness at the advancing side of the second track. The precipitation of chromium carbides in the tempered regions of the multi-pass FSPed specimens became the active sites for preferential corrosion attack in the 3.5 wt.% NaCl solution at 25 °C.
