Ceramic Coating

At MBI we apply ceramic coatings by sophisticated Plasma spray systems. Our ceramic coatings can transform an ordinary metal into a high-performance surface. When applied by high energy Plasma, The coatings are dense, wear, corrosion & heat resistant, inert to acids, alkali and solvents. They improve the properties of any surface they're applied onto. Because of our higher energy application method our coatings have higher particle-to-particle cohesive bonding which translates into higher quality coatings.

Ceramic Coatings for Metal Parts

that can be applied to metal components in order to enhance their functional properties. Most ceramic coatings are electrically nonconductive (making them excellent insulators), have a significantly higher level of abrasion resistance than most metals, and are capable of maintaining their integrity under severely elevated temperatures, sometimes up to 4,500 degrees Fahrenheit. Wear-resistant ceramics, such as titanium nitride and chromium carbide, can be applied to work steels and air-hardening tool steels via chemical vapor deposition (CVD), which is one of the more common application methods currently in use. Before applying a coating, it is important to ensure compatibility between the ceramic material and the metal surface. Much of this compatibility depends on thermal expansion properties, as having expansion rates that differ too greatly can cause a coating to crack when it is being cooled after application. In addition, a diffusion layer typically forms on the metal surface, and this can lead to a coating that is too soft or too brittle for the design specifications. Complementary thermal properties will help to prevent heat checking and improve resistance to wear and fracture.

Manufacturing Applications

Ceramic coatings are often used as barrier materials to enhance the interaction between moving metal parts, such as in the automotive industry. However, they are also increasingly being employed to augment certain manufacturing processes, and exhibit potential for improving the efficiency of some fabricating methods. Ceramic coatings are sturdy and have a high level of lubricity, but due to oxidation concerns, they are typically used in temperatures under 1,200 degrees (F). However, this allows them to be applied to hot forging dies, which operate at lower temperatures. Ceramic coating increases the operational lifespan for these dies, allowing them to produce a greater number of parts before wearing down. Ceramic materials, such as magnesium zirconate and zirconia, exhibiting a high level of hardness, thermal resistance, and elevated melting points are being used as heat barrier coatings for industrial parts.
