Black & White Thermal Control Coatings Comparison Experiment

ABSTRACT In space applications, thermal control, emissivity and absorptivity are critical factors to the optimum performance of space vehicles or satellites. Thermal control coatings (TCC) are designed to have specific radiative properties that are tailored for different specific missions. For example, for solar orbiters, a radiative surface coated with a white coating having low absorptance and…

Black oxide vs acktar vacuum black coating

What Exactly Is Black Oxide Coating And What Does It Do?

Black oxide coating is the process of coating ferrous materials, stainless steel, copper, copper based alloys, zinc, materials with a chemical coating process. It takes products, and it coats them in iron oxide. This provides many benefits. First, it reduces light reflection. This is beneficial because for products such as IR sensors, UV sensors, passive infrared…
