One of the most important parts of the house and kitchen’s fitting are the door handles, which is one of the main components in interior design and decoration, and also is essential for safety. The door handles are made in a variety of types, such as plate doorhandle (one piece), Rozer Doorhandle, knob for a hub, and electronic handle. In addition to the desired application, features such as beauty, design and applied paint are important, as well as wear resistance, corrosion and color change in the fabrication of the handle. In order to prevent occurrence of blackness and wear due to the long time use of the handle, application of the coating on the surface is considered. The application of nanostructured coatings produced by Physical Vapor Deposition (PVD), brings uniformity in thickness, as well as high adhesion to the substrate and varied long lasting durable colors. Iran Handle Company, using the PVD method, produces handles with a TiN nanostructured coating with a high hardness, wear resistance and an attractive appearance.
