摘要
A black high temperature emissivity paint comprises 27.5wt black pigment, 50.5% acrylic resin and 22wt% silicone resin excluding solvent. The black pigment comprises (Co,Fe)(Fe,Cr)2 O4 and Ni. The black high temperature emissivity paint is applied to components of gas turbine engines and the gas turbine engine is run at the gas turbine engines normal operating conditions. The component coated with the black high temperature emissivity paint is viewed by an optical pyrometer and the optical pyrometer is used to determine the temperature of the component. The pyrometer measures the energy radiated by the component. The advantage of the black high temperature emissivity paint is that the colour, and hence the emissivity, remain unchanged at temperatures of 1100 DEG C and greater. This enables the pyrometer to be used without the need to recalibrate the pyrometer to take into account changes in emissivity of the black high temperature emissivity paint. It enables higher temperature use with more accuracy.
