Abstract: A composition for inhibiting corrosion in gas wells includes a pyrazolopyridine derivative. The pyrazolopyridine derivative includes a pyridyl moiety, a first pyrazole moiety, a second pyrazole moiety, and a phenyl moiety. The first pyrazole moiety is bound to the pyridyl moiety. The second pyrazole moiety is bound to the pyridyl moiety. The phenyl moiety is bound to the pyridyl moiety. The composition can be flowed into a wellbore formed in a subterranean formation, thereby inhibiting corrosion in the wellbore.

Abstract: Sol-gel coating formulations including metal oxide particles such as aluminum oxide, calcium oxide, zinc oxide, magnesium oxide, and molybdenum oxide embedded in a hybrid polymer matrix based on a reacted form of a resin composition containing a tetraalkylorthosilicate, an aminoalkylsilane, a dialkoxysilane, and a silanol terminated polydimethylsiloxane. The sol-gel coating formulations are suitable for applications such as anticorrosive protective coatings of metal substrates (e.g. mild steel). These anticorrosive coated metal substrates are evaluated on their hydrophobicity (water contact angle), surface roughness, mechanical strength (e.g. hardness), adhesiveness to the substrate (e.g. critical load), and anticorrosiveness upon exposure to a saline solution (e.g. impedance value).

Abstract: Bearing steel comprising cubic boron nitride (c-BN) and/or nickel coated cBN spark plasma sintered at a temperature in the range of 850-1050° C. is disclosed. The tribological and corrosion resistance of the bearing steel improved with increasing the amount of c-BN. Further improvement in the properties was achieved with the incorporation of nickel coated c-BN, which caused a phase transition of the bearing steel from magnetic to non-magnetic phase accompanied by interdiffusion enhancement between the matrix and c-BN reinforcement.
