Abstract
A component for use in a high-temperature environment such as the coating chamber of a PVD apparatus. A reflective coating on the component serves as a barrier to radiant heat transfer to the component by reflecting thermal radiation. The coating comprises at least one pair of reflective layers, each layer being formed of a material that is essentially transparent to electromagnetic wavelengths of between 500 and 3000 nanometers (nm). In addition, the material of the outermost layer of the pair has a higher index of refraction than the material of the other layer of the pair.
