Abstract
A system for applying a coating to an engine valve and curing the coating using infrared radiation includes a spraying device, an infrared oven, and a movable track. A plurality of engine valves is transported through the system on the movable track. The spraying device applies a protective coating composition on a portion of the engine valves. The coating composition has a high emissivity value that allows the coating to be rapidly and efficiently cured as the coated engine valves travel through the infrared oven.
