“…When chromium is present, the rate of oxidation slows down because chromium oxide is more stable than iron oxide and grows slower than iron oxide [8]. Several studies have shown that a high Cr in the composite may increase the wettability between ceramic and metal [9]. Therefore, it is very necessary to improve the Fe-Cr alloy to make these alloys last longer in the scientific field of metallurgy.…”

“…Therefore, it is very necessary to improve the Fe-Cr alloy to make these alloys last longer in the scientific field of metallurgy. Recently there have been several techniques of strengthening metal matrices, such as alloying, precipitation strengthening, composites reinforcing, solid solution strengthening, and High energy milling may encourage the wettability of immiscible systems during the sintering, facilitate the interaction of component materials which also improve the strength [10][11][12][13][14][15][16].…”

The reinforcement effects of the ZrO2 and the wear and mechanical behaviour of (Fe,Cr)-based alloy composites were investigated. The (100-x) (Fe80Cr20) -(x) ZrO2 composites were fabricated via powder metallurgy. The iron-chromium and ZrO2 powders were efficiently milled and mixed in ball mill. In the Fe80Cr20 alloy, the effect was investigated by changing the ZrO2 composition by 5%, 10%, and 15%. The microstructure feature and consequent wear behaviour of iron and chromium alloys have been studied using the diversified alloy compositions, various sintering temperatures, and various substrates. The blended powder mixture was cold compacted and sintered at 1300°C. The scanning electron microscopy (SEM), elemental mapping, and X-ray diffraction techniques were utilized to assess the microstructural properties of the sintered composites. In addition, the mechanical properties such as hardness, flexural strength, and porosity were examined with variations in ZrO2 composites. The dry sliding wear tests with various normal loads and a constant sliding distance were used to find the composites wear behaviour. The composite containing 10% ZrO2 has shown the maximum flexural strength with 1470 MPa, and hardness 359.8 HV10, respectively, compared to 5% ZrO2 and 15% ZrO2. With a concentration of 10 wt.% ZrO2, the wear resistance is found to be significantly enhanced, while after 10 wt.% ZrO2, its properties deteriorate. In addition to having improved interfacial bonding, lower porosity, and microstructure uniformity, Fe-10

“…Li et al [23] demonstrated that Cr-Ni alloy films could exhibit excellent hightemperature wear resistance. Wang et al [24] demonstrated that Cr-Fe interlayers could improve the wetting behaviours between Al and Zr 2 O 3 /Al 2 O 3 composites. The abovementioned results indicate that alloying of Cr films is a noteworthy attempt to explore the enhanced mechanical and functional properties of the films.…”

Previous studies have dealt with Cr and its alloy films that exhibit promising characteristics as surface modification layers for antiwear, anticorrosive, and decorative applications. However, the effect of Ti alloying on the structure and mechanical properties of Cr films has not been studied. This work aimed to the structure and mechanical properties of Cr-Ti alloy films in the Cr-rich side. To this end, pure Cr, Cr-6 at.% Ti, Cr-11 at.% Ti, Cr-16 at.% Ti, and Cr-21 at.% Ti alloy films were prepared by magnetron sputtering, and the structure and mechanical properties of the films were evaluated. The results indicated that all the films exhibited a Cr-based growth with body-centered cubic structure, and increasing the Ti content decreased the (110) orientation growth of Cr basis. Ti alloying increased the hardness of the films, while leaded to a monotonic decrease in the modulus of the films. The first-principles method was employed to demonstrate that the reduced modulus was determined by the Ti alloying degree, rather than the orientation evolution of the films. The analysis of H/E value suggested that the wear resistance of the films was improved by Ti alloying. The mechanical properties of present Cr-Ti alloy films, and other Cr-based alloy films or metallic glasses in publications were compared and discussed. We proposed that Ti alloying is a considerable way to explore advanced mechanical properties of Cr-based alloy films.
