Surface degradation of materials made up of copper alloys is a serious problem. To address this issue, IASST had developed an environmentally friendly plasma based technology in collaboration with BARC, Mumbai. Currently up-scaling as well as commercial feasibility study of this technology is in progress to explore the marketability of the technology. Images of some Bell metal/brass items coated using IASST patented technology is presented below:
