It is designed to adhere to all metal surfaces and prevents continuous rust. Therefore, it prevents unnecessary damage during cleaning and provides protection against corrosion.
Ceramic coatings
are often used as barrier materials to improve the interaction between moving metal parts, such as in the automotive industry. However, they are also increasingly being used to augment certain manufacturing processes and show the potential to improve the efficiency of some manufacturing methods.Ceramic coatings are robust and have a high level of lubricity, but due to oxidation problems, they are generally used at temperatures below 1200 degrees (F). However, this allows them to be applied to hot forging dies, which operate at lower temperatures. The ceramic coating increases the lifespan of these matrices, allowing them to produce more parts before they wear out. Ceramic materials, such as magnesium zirconate and zirconia, which have a high level of hardness, thermal resistance and high melting points are used as thermal barrier coatings for industrial parts.
Ceramic coatings are used to increase corrosion resistance on the metal surface by spraying zinc and aluminum. There is a wide range of ceramic coating materials that can be applied to metal components to improve their functional properties. The individual ceramic particles are submicron in size and consist of mixtures of selected ceramic materials bonded together and to the substrate. Ceramic coatings are also used to protect automotive parts from the degradation of the material composition due to the friction that occurs during the movement of the parts.
Pressurized gas is then used to spray molten ceramic material onto a surface, producing a coating with a high level of cohesive bonding. It does not adhere to the metal surface like paint; the ceramic coating adheres to the material of the parts. This process is very beneficial for restricting heat loss and degradation of metallic materials, although preparing the surface for ceramic coating is a very difficult job. Most ceramic coatings are not electrically conductive (which makes them excellent insulators), have a significantly higher level of abrasion resistance than most metals, and are capable of maintaining their integrity at very high temperatures, sometimes up to 4,500 degrees Fahrenheit.
Bodycote offers a unique range of thermochemically formed ceramic coatings to prevent wear and corrosion in a wide variety of industrial applications and for every type of surface. For example, a method for coating metallurgical matrices with refractory materials, such as molybdenum and tungsten, employs a plasma spray gun and low-shear compaction to achieve a highly effective and wear-resistant coating. Thermochemically ceramic coatings to provide wear resistance and corrosion protection, in a wide variety of industrial applications, for every type of surface.
