Abstract: A method of inhibiting corrosion of metal during acid stimulation of an oil and gas well that involves treating the oil and gas well with an acidic treatment fluid that includes 10 to 28 wt. % of an acid, based on a total weight of the acidic treatment fluid, and a corrosion inhibitor composition containing gelatin, wherein the gelatin is present in the acidic treatment fluid in a concentration of 0.1 to 10% by weight per total volume of the acidic treatment fluid.

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.
