A method for producing a component made of a steel product coated with an Al—Si protective coating, includes: providing a substrate consisting of a steel produced coated with an Al—Si protective coating, heating the substrate to a temperature T1 such that the Al—Si protective coating is only partially pre-alloyed with Fe of the steel product, cooling the pre-alloyed substrate to room temperature, applying a corrosion protection oil to the surface of the pre-alloyed substrate, wherein the oil consists of a composition containing fatty acid ester, transporting the pre-alloyed substrate to which the oil has been applied, heating the pre-alloyed substrate to which the oil has been applied to a temperature T2 such that the Al—Si protective coating is fully alloyed with Fe of the steel product and the oil is removed without leaving residue, and shaping the re-heated substrate to form the component.

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 invention provides a novel metal corrosion inhibitor containing a compound having a specific structure. The present invention relates to a metal corrosion inhibitor including a compound (X) including one molecule of a mercaptocarboxylic acid or a mercaptocarboxylic acid salt; one molecule of acrylic acid, an acrylic acid salt, or an acrylic acid ester; and one molecule of a monomer (B) represented by the following formula (1), which are bonded to each other: ##STR00001##

Implementations set forth herein relate to systems, methods, and products for preserving a blade(s) of a device, and/or other features of other apparatuses. A blade-preserving product set forth herein can be applied to surfaces of a blade of a personal hygiene product, such as an electric or non-electric razor. The blade-preserving product can include one or more disinfectants that can operate to dissociate organic matter from a surface of the blade. Additionally, the blade-preserving product can include one or more anti-oxidants, such as a carbon nano material, that can reduce a rate of oxidation occurring at the blade, and also mitigate growth of organic matter on the blade. The blade-preserving product can be included in a container with a spray nozzle, thereby allowing the blade-preserving product to be readily dispensed onto a blade before and/or after a user employs the blade.
