Methods of employing corrosion inhibitors with oxidizing and/or non-oxidizing biocides, such as peroxycarboxylic acids, to provide corrosion protected compositions are disclosed. Various corrosion inhibitors further provide biocidal efficacy in addition to the corrosion protection providing further benefits for application of use. Methods of employing corrosion protected biocide compositions, such as peroxycarboxylic acid compositions, for corrosion protection are particularly well suited for treating fluids intended to flow through pipes, namely in the energy industry, water and paper industries, etc. Methods providing suitable corrosion protection in comparison to untreated systems and corrosion protected systems using conventional corrosion inhibitors, such as quaternary amines and imidazolines commonly used in the industry, are disclosed.

The present disclosure is directed to methods, systems and apparatuses for predictively selecting plant extracts for their inclusion in formulations to imparting anti-corrosion properties to coatings for aluminum, aluminum alloys, copper and copper alloys.

Provided herein are methods and compositions for chemical mechanical polishing (CMP) of metals. The present methods and compositions involve the use of a corrosion inhibitor having the general formula C.sub.mH.sub.2m+1(OCH.sub.2CH.sub.2).sub.n-L-R in the CMP slurry composition, where m is an integer between 6 and 11, inclusive of end points, and n is an integer greater than or equal to 6, L is a bond, O, S, R.sup.1, SR.sup.1, or OR.sup.1, where R.sup.1 is a C.sub.1-4 alkylene; and R is an anionic group. The present methods and compositions can be used to achieve a high metal removal rate, while effectively inhibiting metal corrosion during CMP, and are particularly useful for CMP of cobalt (Co).

The present invention relates to development of high performing oil soluble and water dispersible corrosion inhibitor composition for mitigating internal corrosion of crude oil pipelines during storage and transportation of crude oils.
