Abstract

Black ceramic coating has become the important process of metal finishes in solar thermal application. Considerable effort has been expended on developing coatings and absorber materials having high conversion efficiency. This study focused on applying the black ceramic coating using an electroplating process on two types of substrate, which is copper and stainless steel. Black chromium is the best formulation for coating and it is a common use of thermal solar application. The optical properties such as high absorptance, low emittance and metallurgical properties of the combination of black ceramic coating on both substrates are tested and analyzed. It is found that the optical properties of the copper substrate give high absorption, α > 0.95 and low emittance, Ɛ 0.013. Besides that, stainless steel can be the alternative substrate for solar application because it is cheaper than copper. The value of absorptance and emittance for stainless steel is α >0.91 and Ɛ 0.1.
