【Abstract】 In this paper, we have studied the titanium carbide film which is used in the vacuumcollecting tubes to selectively absorb the solar energy. The film was deposited onto analuminium substrate using a single titanium target reactive d. c. magnetron sputtering.Its optical absorptance of solar energy is α=0.917, and thermal emittance is ε=0.07.更多还原
