“…The roughness of the material controls the wear mechanism and behaviour of materials as reported by many researchers such as [31,32].in the experiments, the roughness of the counterface was fixed to less than 1 µm Ra. The modifications in the roughness of the composites which occurred after each test was determined and plotted in Fig.…”

In this study, hand lay-up technique was used to fabricate epoxy composite based on jute fibre mates. Three different orientations wew considered in the fabrication of the composites. The characteristics of the material removal from the surface of the composite due to sliding condition was investigated. Different applied loads were considered to gain different shear force in the interface. Scanning electron microscopy was used to examine the influence of the shear force on the interaction between the fibre and the resin after sliding at different orientations. The outcome would be significantly contributed to the knowledge of composite science and tribology. The main findings of the work was that fibre orientation has very significant influence of the wear and frictional performance of jute fibre reinforced epoxy composites. Sliding distance controls the running in and steady state wear behaviour of the composites especially when the composite was tested in parallel and antiparallel orientations. Wear resistance of the composites found to be better in the antiparallel orientation followed by parallel and then normal. Jute fibres gave very promising results to replace glass fibres for the same composites at the same operating conditions.

“…In order to further improve their mechanical properties and oxidation resistance, CrAlSiN films have been developed [1,2]. CrAlSiN films were synthesized by substituting smaller and oxidation-resistant elements such as Si and Al into the Cr sites of CrN films, which resulted in solution hardening with grain refinement [3] and precipitation of Si 3 N 4 [4][5][6], leading to increased hardness [7], wear resistance [8][9][10], and thermal stability [3,4,[11][12][13]. The good oxidation resistance of CrAlSiN films is attributed to the formation of protective oxides such as Cr 2 O 3 , Al 2 O 3 , and SiO 2 during oxidation at 800-1150 o C for 1-100 h in air [2,4,11,14,15].…”

Cr 25.2 Al 19.5 Si 4.7 N 50.5 thin films were deposited on steel substrates by cathodic arc plasma deposition. They consisted of alternating fcc-Cr(Al)N/hcp-Al(Cr,Si)N nanolayers. They were corroded at 900 and 1000 o C for 5-100 h in N 2 /0.1%H 2 S gas atmosphere. Their corrosion mechanism, the structure of the formed scales, and the role of film-constituting elements during corrosion were studied. Despite the presence of hydrogen and sulfur in the corrosion gas, the films displayed good corrosion resistance because Cr, Al, Fe preferentially reacted with impurity oxygen in the corrosion gas to form Cr 2 O 3 , Fe 3 O 4 , and amorphous Al 2 O 3 owing to the thermodynamic stability of these oxides. The films were corroded by the outward diffusion of Cr, Al, Fe and nitrogen as well as the inward transport of sulfur and then oxygen. Silicon in the film was primarily oxidized by the inwardly transported oxygen. This study aimed to investigate the high-temperature corrosion behavior of nano-multilayered Cr 25.2 Al 19.5 Si 4.7 N 50.5 thin films in a serious H 2 S-containing environment.

“…The SEM images of the surfaces of A1, A2 and A3 samples are shown in Figure 3. The morphology analysis of these samples reveals a typical characteristic of coatings deposited by PVD processes, the presence of pores [27][28][29][30] . A more uniform layer was obtained in the treatment at 450 °C, Figure 3b, which is evidenced by the absence of void observed in the coatings deposited at 400 °C and indicated by arrows in Figure 3.…”

Influence of Hastelloy’s Cathodic Cage Plasma Deposition on Corrosion Resistance of AISI 304 Stainless Steel and of AISI D6 Tool Steel

AISI D6 tool steel and AISI 304 stainless steel are among the most widely used material in the industry. However, this application field can still be expanded through the coatings deposition. In this regard, the objective of this work was to evaluate the impact of coatings application by cathodic cage technique using Hastelloy's cathodic cage, on corrosion resistance of these steels. Two treatment temperatures were compared. The samples were characterized by Optical Microscopy, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-Ray Diffraction with the application of the Rietveld routine and corrosion test. The results showed the formation of multiphase layers that contributed to corrosion potentials reduction for treatments at 400 °C, being more effective when applied on AISI D6. It was observed that the corrosion resistance is influenced by the temperature, which was attributed to the precipitation of chromium nitride and iron oxide at 450 ºC.
