Protective properties of oil-soluble corrosion inhibitors based on alkenylsuccinic anhydride

Conclusions Additives and corrosion inhibitors based on alkenylsuccinic anhydride have been studied in relation to their effects on the corrosion of ferrous and nonferrous metals under conditions of chemical, electrochemical, and mixed chemical/electrochemical corrosion.A series of salts of alkenylsuccinic acid has been synthesized, also succinimides based on urea, and a complex corrosion-inhibiting additive.It has been shown that, for the protection of engines and mechanisms against corrosive wear, use should be made of oil-soluble, multifunctional, complex additives that will provide simultaneous protection of metals against chemical and electrochemical corrosion.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 10, pp. 38–41, October, 1970.     

Optical and structural properties of Cu<Subscript>2</Subscript>ZnSnS<Subscript>4</Subscript> thin films obtained by pulsed laser deposition in a H<Subscript>2</Subscript>S atmosphere with subsequent annealing in a N<Subscript>2</Subscript> atmosphere

The structural and optical properties of Cu₂ZnSnS₄ thin-film layers formed by reactive pulsed laser deposition in a H₂S atmosphere at room temperature with the use of a Cu metal target and a Zn–Sn alloy target are studied in relation to the parameters of annealing in a N₂ atmosphere.
