Herein, we report low-cost and rare-earth-free Cu-doped Mg-Al alloys for drill-free plugging applications and present the influence of Al content on degradation behavior. The phase composition and microstructure of fabricated alloys were characterized by using a scanning electron microscope (SEM) and X-ray diffractometer (XRD). Also, degradation properties were investigated using hydrogen evolution tests and the electrochemical measurements. The results reveal that the Al content is directly related to the proportion of secondary phases, such as Mg2Cu, Mg17Al12, and MgAlCu. Moreover, the Mg17Al12 and MgAlCu phases are distributed at α-Mg grain boundaries, whereas the MgAlCu phase is distributed within the Mg matrix. Acceleration of degradation rate is found due to microgalvanic corrosion in Mg-xAl-2Cu (in wt.%, named as ACx2, x = 0, 3, 5, and 9) alloys. In this regard, Mg2Cu, Mg17Al12, and MgAlCu phases act as a microgalvanic cathode against anodic magnesium matrixes. As such, the degradation rate of ACx2 alloys in 3.5% NaCl solution is ranked from AC02, AC32, AC52, to AC92. In this context, the AC02 alloy shows the fastest degradation rate, 46 times higher than the AC92 alloy. This may provide a practical solution to develop good alternatives for drill-free plugging materials.

“…If the initial degradation rate is too rapid, osteolysis may occur, leading to the inferior bone tissue regeneration [ 43 ]. According to the corrosion mechanism of magnesium alloy, its corrosion degradation in physiological environment will produce hydrogen and hydroxide, resulting in the increase of pH value and the accumulation of Mg 2+ [ 44 ]. Therefore, the degradation behaviors were investigated by measuring the pH changes and Mg 2+ release behaviors of the different samples immersed in SBF solution.…”

The in vivo fast degradation and poor biocompatibility are two major challenges of the magnesium alloys in the field of artificial bone materials. In this study, graphene oxide (GO) was first functionalized by chitosan (GOCS) and then immobilized on the magnesium alloy surface, finally the complex of heparin and bone morphogenetic protein 2 was incorporated on the modified surface to synergistically improve the corrosion resistance, anticoagulation, and osteogenesis. Apart from an excellent hydrophilicity after the surface modification, a sustained heparin and BMP2 release over 14 days was achieved. The corrosion resistance of the modified magnesium alloy was significantly better than that of the control according to the results of electrochemical tests. Moreover, the corrosion rate was also significantly reduced in contrast to the control. The modified magnesium alloy not only had excellent anticoagulation, but also can significantly promote osteoblast adhesion and proliferation, upregulate the expression of alkaline phosphatase and osteocalcin, and enhance mineralization. Therefore, the method of the present study can be used to simultaneously improve the corrosion resistance and biocompatibility of the magnesium alloys targeted for the orthopedic applications.

ÖZET: Dünya petrol rezervlerinin hızla tükenmesi, artan yakıt ekonomisi talepleri ve egzoz emisyon değerlerine getirilen yasal sınırlamalar otomotiv endüstrisini modern hafif yapılara yönlendirmiştir. Otomobillerde kütle azaltımı ile hem yakıt verimliliğinin sağlanması hem de yanma sonucu açığa çıkan zararlı egzoz emisyonlarının en aza indirgenmesi hedeflenmiştir. Bu bağlamda üstün özelliklere sahip malzemelere ihtiyaç duyulmuştur. Magnezyum ve alaşımları düşük yoğunluk, yüksek özgül dayanım, kolay geri kazanım ve mükemmel sönümleme kapasitesi gibi karakteristik özellikleri ile otomotiv uygulamaları için en dikkat çekici yapısal malzemeler olarak ön plana çıkmaktadır. Bu malzemeler otomobillerin iç donanım, karoseri, şasi, güç aktarma organları ve araç ön alanı gibi temel sistem ve bileşenlerinde kullanılarak ağırlıkta önemli bir kazanım sağlayabilir. Böylece gerek yakıt sarfiyatı gerekse de insan sağlığı ve çevre kalitesi açısından ciddi tehdit unsuru oluşturan egzoz emisyonları minimize edilebilir. Bu çalışmada, magnezyum ve alaşımlarının otomotiv endüstrisindeki önemine, mevcut ve olası uygulamalarına dikkat çekilmek istenmiştir.
