The specific embodiment of the present disclosure provides a protective coating. An anticorrosive coating having a compact rigid molecular structure is formed by plasma polymerization coating of monomers including alicyclic epoxy structural units, and a hydrophobic coating is simultaneously formed by plasma polymerization coating on the anticorrosive coating, thus, coatings with excellent protective performance to the substrate are formed.

The present disclosure relates to a housing for an engine component. The housing comprises a wall made of a light alloy. An epoxy primer coating having at least one layer of a primer containing at least 80 wt. % epoxy covering the wall. An intumescent paint coating having at least one layer of intumescent paint directly covering the epoxy primer. And, an epoxy top coat directly covering the intumescent paint coating, the epoxy top coat having at least one layer of a top coat containing at least 80 wt. % epoxy.

The patent application discloses a degradable composite with coatings. The light metal workpiece with enhanced surface protection may comprise a light metal matrix having an exposed surface; a light metal oxide ceramic layer formed in at least a portion of the exposed surface; and a non-transparent metal alloy layer directly on the light metal oxide ceramic layer.

A coating with strong adhesion for medical magnesium alloys, including a magnesium phosphate or calcium phosphate layer as an inner layer and a hydrophobic polymer layer as an outer layer. The inner layer is attached to the medical magnesium alloy; and the outer layer is attached to the inner layer. A preparation method of the coating is also provided, including: (S1) carrying out surface treatment on a medical magnesium alloy substrate; (S2) preparing a solution including magnesium salt/calcium salt and phosphoric acid/phosphate followed by pH adjustment and heating; (S3) soaking the medical magnesium alloy substrate in the solution followed by washing and drying to obtain a magnesium phosphate/calcium phosphate layer-coated medical magnesium alloy sample; and (S4) depositing a hydrophobic polymer layer on the medical magnesium alloy sample through chemical vapor deposition (CVD).

The disclosure relates to a metal electrode or current collector for an energy storage device. The surface of the electrode or the current collector includes multiple blind hole-like recesses spaced apart from each other. The surface structured in this way is coated with a solid polymer electrolyte. The recesses are filled with the solid polymer electrolyte, as well as a primary or secondary energy storage device including the same.

A process for the corrosion protection of metals such as magnesium, aluminium or titanium, where at least two steps are used, including both plasma electrolytic oxidation and chemical passivation. The combination of these two processing steps enhances the corrosion resistance performance of the surface beyond the capability of either of the steps in isolation, providing a more robust protection system. This process may be used as a corrosion protective coating in its own right, or as a protection-enhancing pre-treatment for top-coats such as powder coat or e-coat. When used without an additional top-coat, the treated parts can still retain electrical continuity with and adjoining metal parts. Advantages include reduced cost and higher productivity than traditional plasma-electrolytic oxidation systems, improved corrosion protection, greater coating robustness and electrical continuity.

The invention provides a film-forming composition containing a tannic acid derivative in which hydrogen atoms in at least some of hydroxyl groups of tannic acid are substituted by a chain hydrocarbon group having 3 to 18 carbon atoms. The film-forming composition of the invention can provide a good enough film on a variety of substrate materials, having improved effects on rust prevention or the like.

Reactive nanocomposites comprising a metal nanoparticle functionalized with one or more layers of self-assembled protein cages and methods of making the same. The reactive nanocomposites according to the present invention demonstrate improved reaction kinetics and enhanced exothermic behavior.

A bioabsorbable implant for non-luminal region comprising: a core structure including a magnesium alloy having a predetermined shape; a first corrosion-resistant layer containing a magnesium fluoride layer as a main component formed on the core structure via fluorination of a surface of the magnesium alloy; and a second corrosion-resistant layer containing a parylene formed on the magnesium fluoride layer.

The present disclosure is drawn to covers for electronic devices. In one example, a cover for an electronic device can include an enclosure with a light metal substrate joined with an insert molding plastic part, and a protective treatment layer on the light metal substrate and the insert molding plastic part. A transparent primer coating on the protective treatment layer, and a paint coating on the transparent primer coating. A milled edge along the insert molding plastic part, wherein the milled edge cuts through the paint coating to expose the transparent primer coating.
