Metal coatings are used to separate structural metals from corrosive environments. They can be categorised into two groups: those that are more active than the base metal, such as zinc, and those that are more noble, such as chromium. Metal coatings are applied by processes such as chemical vapor deposition, thermal spraying, and electroplating. They are used to protect the underlying metal substrate from corrosion and other environmental factors. In the context of Pokémon, a Metal Coat is a type of held item that allows certain Pokémon to evolve and boosts the power of their Steel-type moves. For example, a Scizor holding a Metal Coat and using the Technician ability will increase the power of its Bullet Punch move.

What You'll Learn
Metal coatings for corrosion protection
Metal coatings are essential for protecting metals from corrosion, which occurs when metals are exposed to natural electrolytes like salt, oxygen, and water, forming oxides on the surface. Corrosion is a natural process that reverses the metal to its original state of ore, weakening it and making it more prone to damage. Most metals, especially stainless and carbon steel, are susceptible to corrosion.
There are various metal coating options available, each with its own advantages and considerations:
Zinc Coatings
Zinc is a popular choice for steel pieces due to its innate resistance to corrosion. It acts as a barrier between the iron or steel and the environment, forming a dense, adherent layer. Common zinc coating methods include sheet metal fabrication techniques such as hot-dip galvanizing, mechanical or zinc plating, and electrogalvanizing. Zinc coatings can also be applied through painting techniques like zinc-rich painting and metalizing/zinc spraying. Zinc is also available in a variety of colors and is thin, making it a versatile option.
Polyurethane Top Coat
Polyurethane top coat, also known as a urethane finish or epoxy coating, is a widely used corrosion prevention method, especially in commercial buildings that use stainless and carbon steel. It is an all-weather sealant that protects against corrosion, UV rays, and snow. It also provides a durable and aesthetically pleasing finish to the metal.
Powder Coatings
Powder coatings are another effective option for corrosion protection. They can be applied by spraying electrostatically charged powder onto the metal or by dipping the piece into a bed of fluidized powder. The coated piece is then cured in an oven, resulting in a firm and durable finish. Powder coatings can be customized with different colors and formulations to meet specific project needs, such as additional protection from abrasion, chemical exposure, or UV rays.
Inorganic Zinc Coatings
Inorganic zinc coatings are highly effective in preventing rust on steel and protecting against environmental factors like saltwater and harsh weather conditions. They are commonly used in chemical plants and refineries to shield equipment from deterioration.
Epoxy Coatings
Epoxy coatings, similar to zinc-rich coatings, offer excellent protection for steel against rust, moisture, abrasion, and chemical erosion. They are also cost-effective, making them a budget-friendly option.
Anodisation
Anodisation is a popular method for improving corrosion resistance on aluminium. It involves immersing the material in a conductive solution, typically a low pH acid bath, and applying an electrical current to create an oxidation reaction at the metal surface. This process thickens the natural oxide on the surface, creating a protective layer of aluminium oxide. The thickness of the coating can be adjusted by varying the coating time, making it versatile for different applications.
Plasma Electrolytic Oxidation (PEO)
Plasma Electrolytic Oxidation (PEO) uses plasma discharges to transform the metallic surface of light metals, forming a hard and dense adhesive oxide layer. It is a three-stage process that includes oxidation of the substrate, co-deposition of elements from the electrolyte, and modification of the resulting layer by plasma discharge. PEO is particularly effective for lightweight metals such as aluminium, titanium, and magnesium, providing higher hardness and chemical passivity compared to anodised coatings.
Chromate Conversion Coating
Chromate conversion coating is a highly effective corrosion resistance technique, despite facing increasing regulatory scrutiny. It involves applying chromic acid, sodium, potassium chromate, or dichromate solutions to clean metallic surfaces, leaving a passive film containing chrome (IV) oxide and hydrated compounds. This film provides high corrosion resistance and can self-heal by reforming a protective oxide film in damaged areas exposed to atmospheric oxygen.
Other Coatings
Other coating options include cadmium, a soft white metal that acts as a sacrificial coating, corroding away and protecting the underlying substrate. Black oxide coating is another inexpensive option, commonly used on black fastener bolts or nuts, although it offers limited corrosion resistance.

Metal coatings for Pokémon evolution
Metal coatings are essential for the evolution of certain Pokémon species. Introduced in Generation II, the Metal Coat is a type of held item that enables specific Pokémon to evolve while also enhancing their Steel-type moves.
The Metal Coat is primarily associated with the evolution of Onix into Steelix and Scyther into Scizor. When these Pokémon are traded while holding the Metal Coat, they undergo their respective transformations, with the item being consumed in the process. The Metal Coat boosts the power of Steel-type moves by 20% in Generations IV and beyond, and by 10% in Generations II and III.
In Pokémon Legends: Arceus, the absence of held items means that the Metal Coat simply needs to be used on Onix or Scyther to initiate their evolution, although it is still consumed. Obtaining a Metal Coat can be challenging, with a very low drop chance of around 1% from spinning PokéStops and Gyms. However, players can increase their chances by taking advantage of bonuses, such as the 7th-day streak bonus, which offers a higher probability of receiving evolution items.
The Metal Coat plays a crucial role in the evolution of select Pokémon, serving as a catalyst for their transformation into more advanced forms. It is a sought-after item for trainers aiming to evolve Onix and Scyther into their Steel-type evolutions, Steelix and Scizor, respectively.
