MAC Introduces DLC Coatings
Morgan Advanced Ceramics (MAC) has introduced its DiamonexR Diamond-like Coatings (DLCs). Diamonex is described as a high performance surface coating, providing ceramic hardness, excellent chemical resistance and low friction. In addition, the coating is available in either 'electrically insulating' or 'charge dissipating' forms.Claimed to be ideal for applications in the semiconductor and electronics industries - and cleanroom environments - the DLC is used for reducing particulate shredding from substrates, increasing wear life and reducing surface friction of ceramic, glass and plastic products.
Using patented plasma or ion beam chemical vapour deposition (CVD) technologies, MAC created a coating with chemical and physical properties similar to diamond but without long-range crystalline order.
Similar to diamond, the Diamonex DLC coatings exhibit high hardness, a low coefficient of friction, chemical resistance, electrical insulation and transparency at certain optical wavelengths. They are applied to a substrate at near ambient temperature, thereby preventing distortion to the product being coated.
The high degree of vapour ionisation used in MAC's processes for DLC produces highly dense, conformal coatings with excellent adhesion, explains the company. These coatings can be specifically engineered to meet the performance requirements of each unique application.
