    Application of Zinc-Nickel Alloy Technology in Long-term Anticorrosion of Coal Mine Fasteners Yi Chunlong, Ou Xuemei, Tang Dafang (China University of Mining and Technology, Xuzhou, Jiangsu 221008, China) The systematic study on the properties of zinc-nickel alloy coatings. 1Overview the poor underground coal mine environment, complex water quality components, accompanied by sulfur dioxide Application of Zinc-Nickel Alloy Technology in Long-term Anticorrosion of Coal Mine Fasteners Yi Chunlong, Ou Xuemei, Tang Dafang (China University of Mining and Technology, Xuzhou, Jiangsu 221008, China) The systematic study on the properties of zinc-nickel alloy coatings. 1 Overview The underground coal mine environment is harsh, the water quality is complex, and it is accompanied by various harmful gases such as sulfur dioxide. The fasteners in the mine are in a humid and corrosive environment for many years. The traditional methods of anti-corrosion fasteners such as galvanizing are used underground for 1 year. The left and right will rust and bite. With the successful application of long-lasting anti-corrosion technology of arc spraying on wellbore equipment, the long-term anti-corrosion problem of coal mine fasteners has become increasingly prominent, and the protection technology of fasteners has also put forward higher requirements. At present, most of the protective treatment of fasteners adopts traditional processes such as galvanizing and hot-dip galvanizing. In the harsh environment, the corrosion resistance cannot meet the requirements. In severe cases, even corrosion leads to early failure and causes a safety accident. Therefore, it is of great significance to study the corrosion pr

    Heat treatment of nickel-bearing cast titanium aluminum alloy
    Many titanium-aluminum alloy aviation and automotive engine parts are molded using precision casting technology. Heat treatment is one of the key technologies to improve the microstructure of cast titanium aluminum alloy. The original as-cast microstructure of cast titanium aluminum alloy is generally γ-TiAl/α2-Ti3Al layer structure. The lamellae are coarse and the distribution of the lamella size and orientation is not uniform. The high-temperature heat treatment in the alpha single-phase zone can achieve homogenization of its structure. However, due to the coarseness of the original structure and the difficulty in controlling the growth of the α-phase grains at high temperatures, the fully-laminated fully-titanium-aluminum (FL) laminates usually still have thick lamellar groups. In order to improve the room-temperature tensile plasticity of cast titanium aluminum alloy, a thin full-thickness microstructure of cast titanium alloy was successfully obtained through a multiple heat treatment process [5,6]. The process includes homogenization of 1 alpha single phase zone, thermal cycling from 2900 to 1150 °C, isothermal treatment at 31150 °C, and 4 reheating to a short time isothermal treatment slightly above the temperature of Τα. However, this heat treatment process is more complicated and the processing cycle is longer, which is not conducive to engineering applications. In this paper, the heat treatment process of nickel-microalloyed cast Ti-46.5Al-2.5V-1.0Cr (atomic percent, the same below) alloys was studied, and the micro-alloying of nickel simplified the homogenization and refinement of the cast titanium-aluminum alloy. The mechanism of the heat treatment process and the mechanism of the formation of fine full-thickness titanium-aluminum

    Obama, Trump meet at White House to begin transition of power
    WASHINGTON - US President Barack Obama said Thursday he and President-elect Donald Trump had a wide-ranging conversation during their first post-election meeting at the White House. "My number one priority in the coming two months is to try to facilitate a transition that ensures that our president-elect is successful," Obama said, adding that if Trump succeeds, "then the country succeeds." In light of the deep rift among the US society that became evident during the election, Obama said "it is important for all of us, regardless of party, regardless of political preferences, to now come together to deal with many of the challenges we face." For his part, Trump said "A lot of different situations" were discussed during the one-and-half-hour meeting, which was much longer than expected. Trump also expressed the eagerness to work with the government and Obama in the future. The meeting was the first such event held between Obama and Trump since the former real estate billionaire was elected president on Wednesday. Obama has said Wednesday during a speech acknowledging the election result that despite of the differences between him and Trump, it's paramount to make sure the transition was peaceful. The incoming first lady and vice president also accompan

    Steel prices may fall after the first rise in October
    Preview:This year In July and August, Surprisingly,the steel prices rose sharply against the market trend, While during the expect-able market of "golden nine silver ten",the Nickel Alloy price dropped constantly in September,High production season while low reward the phenomenon renewed again.For October which just past a long holiday, steel prices may fall after the first rise. Limits on Steel Production in Tangshan Rose Again The National Day in China has just passed,the market performance is relatively low, Limits on Steel Production re-entry in Tangshan steel market. Tangshan Was forced to conduct environmental improvements from 10 October to 20 October,specific requirements are listed below: Those Iron and steel enterprises which have not passed sintering tests have to reduce50% production of steel.Those enterprises who has passed can produce normally, while the pollutant in no way could exceed the pouring standards; Steel rolling enterprises those have not completed the transformation of coal gas must stop producing, those have can produce as usual. Although there are many uncertainties in the specific measures linked to limit production, but the market sentiment in depression for a long time be pulled up again.Steel trade company has the ambition and the manufacturer have taken advantage of the very moment, the active will in exploring lifting is also rose. Inventory pressure is as usual Because early in this year,the Inconel 600 rebounded sharply, profits of the steel manufacturer improved significantly, many steel mills refreshed by the profits,the yield is also high.
