Surface Engineering

The Surface Engineering Division of UES is primarily involved in modifying the surfaces of solid materials, for various applications, without affecting their bulk characteristics. A variety of surface modification processes are used to alter physical, chemical, electrical and optical properties of the materials surfaces. The Surface Engineering Division primarily offers physical vapor deposition (PVD) and to some extent chemical vapor deposition (CVD) coating process as the primary means to modify friction, wear, erosion, corrosion and oxidation characteristics of materials surface. The Division is well equipped for coating deposition utilizing cathodic (filtered, direct) arc, magnetron sputtering, electron (e) beam and thermal evaporation techniques. In addition to PVD and CVD processes, chemistry based processes such as metal-organic deposition (MOD) are also available for the deposition of high temperature super conductor coating. The Division is equipped with Tandetron- a high energy ion-implanter for modifying the electrical (with concomitant physical/chemical) characteristics of the materials surface. Moreover, the Surface Engineering Division offers testing facilities for tribological, mechanical and microstructural characterizations.
