“…Including 4.40 wt.% of Cr to Al 12 (Fe,Cr) 3 Si 2 minimized the value of its mesh parameter in the BCC arrangement, from 12.71 to 12.62 Å. Thereby, Cr atoms behave as a stabilizing agent permitting the development of this metastable state with a maximum compactness degree, improving its microhardness values [27]. Moreover, Fe and Cr elements correspond to the quaternary period and their atomic radius is similar.…”

In this study, using mixtures of pure Al, Si, Mn, and Fe powders, the α-Al9FeMnSi intermetallic compound was formed onto AISI 304L stainless steel samples by reactive sintering. The processing parameters were temperature (800, 850, and 900 °C) and applied pressure (15 and 20 MPa), using a constant holding time of 7200 s. In this paper, the influence of pressure and temperature on the microstructure, microhardness, and wear resistance of the formed layers was studied. Using X-ray diffraction (XRD), scanning electron microscopy (SEM), microhardness testing, and wearing measurements (pin on disc tests), the cross-section and top side of the coatings were observed and analyzed. We were able to determine the phase composition of cladded layers and interfaces as well as their morphology. The results indicated that several layers were formed during reactive sintering, i.e., an Al-diffusion layer on the top of the substrate, an interface, and the α-Al9FeMnSi coating itself. The microhardness values of the different layers formed were determined, ranging from 400 to 500 HV for the intermetallic coating, to 120 HV for the substrate. In this way, it was found that the formed intermetallic coating is suitable to increase the corrosion resistance of stainless steel. Additionally, all the coating showed high adherence to the substrate, exhibiting high microhardness and wear resistance. Pin on disc wearing tests showed the wearing mechanisms are predominantly delamination and ablation of the cladded layers and substrate.

“…Novák et al, [42] juga mendapati bahawa tahap pengoksidaan dan kekerasan aloi Fe-Al-Si didapati meningkat apabila dioksidakan pada suhu melebihi 600°C. Perbezaan ditunjukkan oleh penemuan yang didapati oleh Frutos et al, [43] yang menyatakan bahawa salutan logam yang mengandungi Al-31at%Si bertindak sebagai lapisan pelindung kepada logam AISI 316 LVM keluli tahan karat hanya pada suhu 900°C sahaja. Pada suhu kurang daripada 900°C, salutan logam tersebut tidak menunjukkan kesan rintangan oksida yang baik.…”

“…Dalam kajian ini, peratus komposisi 5% Si daripada penambahan logam pengisi TLP 4043 yang terdapat dalam struktur terkimpal STK 4043 menunjukkan kesan rintangan terhadap pengoksidaan seawal suhu 400°C. Ini bertentangan dengan Frutos et al, [43] yang menunjukkan bahawa salutan logam dengan peratus 31 at.% Si, ia bertindak sebagai lapisan pelindung kepada logam pada suhu 900°C. Ini dapat disimpulkan bahawa walaupun dengan kehadiran Si dalam peratusan yang rendah masih membolehkan ia bertindak sebagai lapisan pelindung walaupun pada suhu yang rendah.…”

At high temperatures the Al-Mg-Si alloy structure is characterized by low resistance due to the complex oxidation effects involving the formation of layers or scale oxides and internal degradation. The situation becomes more complex when this alloy undergoes a welding process of metal bonding that involves heating and cooling. Subsequently, the welded structure is exposed to high temperature oxidation resulting in different oxide formation and phase changes. Therefore, the present study aims to determine the effect of high temperature oxidation on Al-Mg-Si alloy welded joint using ER 4043 (Al-5% Si) filler metal. The analysis and characterization of samples include morphology and microstructure using OM and SEM / EDX, and the oxide phase was determined using XRD. The addition of 5% Si from the filler metal and the formation of SiO2 on the surface of the welded structure due to the oxidation exposure was found to be effective in lowering the oxidation level by reducing penetration of oxygen diffusion into the alloy substrate. SiO2 also helps strengthen the Al2O3 protective layer. In conclusion, the use of an ER 4043 as a filler metal containing a 5% of Si as a major secondary element in the Al-Mg-Si welded structure is suitable for high temperature applications.

“…The elongation of the average human life observed since the 1970s, and the aging of highly developed societies which is especially noticeable especially in Western Europe, and the observed increase in interest in extreme sports with a high degree of injury rate, forced the introduction of new procedures and implants in the field of orthopedics, reconstructive surgery and prosthetic dentistry. The development in this area is associated with the introduction to the clinical practice of metal implants made of LVM 316 stainless steel and titanium and its alloys, in particular [1,2]. Application of the so-called plates for osteosynthesis, screws, bone screws and rods have revolutionized the treatment of complicated fractures, the fusion of bone fragments and articular alloplasty thanks to which mainly elderly people's locomotor opportunities and relatively comfortable living conditions were restored.…”

The present review paper focuses on the current state of the art of the alumina-silicate ceramics and surface modifications of ceramics dedicated as fillers in composites with carbon fiber. The use of aluminum-silicates in the form of a cenosphere due to their outstanding properties, i.e., low density, high hardness, and total chemical inertness seem to be promising in biomaterial engineering applications. First of all, the possibilities of the composites application in orthopedic and prosthetic implantology. The following section discusses problems with the use of aluminum silicate ceramics and their processing. Subsequently, in the paragraphs to follow, the possibilities of modifying the surface with chemical methods are discussed, among others oxidation, chemical methods like ionic liquids etching, silanization, and physical processes i.e., thermal treatment. In the summary, the directions of development of ceramic-carbon fiber composites and the primary deficiencies of these composites on which to focus on and solve are discussed.
