Abstract
A scale-inhibiting water heater element is provided. The water heater element is coated with a diamond-like coating which has low surface tension to keep scale from forming, and is thermally conductive, which helps prevent overheating. The scale-inhibiting water heater element may be manufactured, for example, by coating a standard water heater element with an amorphous silicon adhesion layer, and then applying a diamond-like coating using a pulsed-glow discharge process.
