The effects of annealing treatments on the microstructure, elastic/mechanical properties, wear resistance and corrosion behavior of rod-shaped Ti40Zr10Cu38Pd12 bulk glassy alloys, synthesized by copper mold casting, are investigated. Formation of ultrafine crystals embedded in an amorphous matrix is observed for intermediate annealing temperatures, whereas a fully crystalline microstructure dev...

Since thermally sprayed zinc and aluminum coatings were invented 100 years ago, they have realized extensive industrial applications for steel structure protection in a variety of fields nearly been proven to be effective reliable. However, it has seldom reported the ship industry China since many workers worry about risk rapid corrosion, especially harsh environments such as South Sea. In this...

As a new type of energy harvesting device, the triboelectric nanogenerator (TENG) can convert almost all kinds of mechanical energy into electricity based on the coupling of triboelectrification and electrostatic induction. Here, a novel TENG is constructed with a conducting polymer polypyrrole nanowire (PPy NW) electrode, which is prepared by an electrochemical polymerization method with anodi...

Magnesium alloy AM60 has high duc and toughness, which is expected to increase in demand for automotive applications. However, it is too active, and coatings have been extensively studied to prevent corrosion. In this work, a Ba-containing composite phosphate film has been prepared on the surface of AM60. The composition and formation mechanism of the film have been investigated using a scannin...

Cultural heritage metallic artifacts are often subjected to environmental factors that promote degradation through corrosion processes. Anticorrosion protection is needed both for the long-term preservation of outdoor monuments and short-term conservation archaeological artifacts. In this work, functional nanocoatings based on ZnO nanoparticles (NPs) in a silica matrix prepared as replacement c...

Thermal and microwave reactions between [PcSn(IV)Cl2] (1) and the potassium salts of eight fatty acids (2 a-h) led to cis-[(RCO2)2Sn(IV)Pc] compounds (3 a-h) in yields ranging from 54 to 90 %. Compounds 3 a-h were fully characterized by elemental analysis, spectroscopy (IR, UV/Vis, multinuclear NMR), and seven X-ray diffraction structures, whereby two different allotropes were observed in two c...

Basalt rockwool wastes with large output, which are toxic and require expensive environmental treatment, produced during the production of rock wool. Hence, it is urgent to find an effective method reuse these materials. In this study, polyaniline (PANI)-coated basalt (BRWs) were prepared as fillers serve in coatings for anticorrosion study. Results show that PANI-coated BRW (PANI@BRW) had enha...

The advantage of nanolayers that can replace the traditional inhibitors of solids is the significant decrease in chemicals. The consequence is a lower environmental pollution. On a copper surface, special hydroxamic acid amphiphiles (CnH2n+1CONHOH, n = 9–17) were used in self-assembled molecular layers (SAM). The impact of time in SAM formation as well as the carbon chain length in the amphiphi...
