Sputter Coater
Over the past few decades, technological advances have made it possible to deposition of the thin films under vacuum which referred to as "Hard Coatings". These coatings have different applications due to their special structural and physical properties as protective coatings. Hard coatings consist of nitrides, carbides and borides of intermediate metals such as titanium or carbon coatings such as diamonds. These coatings have many applications in improving tools (such as cutting and forming machines) and machine parts like valves. Properties of a thin film of hard coatings can be classified as follows: Structural characteristics such as thickness, crystallography, chemical composition, surface morphology and roughness.Physical and chemical characteristics such as density, electrical properties, magnetic properties, thermal, optical, oxidizability and corrosion.Mechanical properties such as hardness, adhesion, mechanical stress and friction.
