In the present work, a monolayer of micro-nano scale TiN/TiC-Ni/Mo ceramic solar spectral selective coating was deposited on the stainless steel substrate by laser cladding. The absorptance (α) and emittance (ε) of the coating prepared at the mixed scale of TiN/TiC-Ni/Mo were 80.1% and 2.24%, respectively. After annealing at 600 °C for 24 h, the absorptance increased to 80.8% and the emittance was 1.9%. The ratio of absorptance to emittance is α/ԑ = 42.52. This study showed that the thermal stability and optical properties of the ceramic coating was excellent under high temperature. It also provides a new idea for the preparation of solar absorbing coatings in the future.

在本工作中，通过激光熔覆将单层微纳米TiN / TiC-Ni / Mo陶瓷太阳光谱选择性涂层沉积在不锈钢基板上。以TiN / TiC-Ni / Mo的混合比例制备的涂层的吸收率（α）和发射率（ε）分别为80.1％和2.24％。在600°C退火24小时后，吸收率增加到80.8％，发射率是1.9％。吸收率与发射率之比为α/ԑ＝ 42.52。研究表明，高温下陶瓷涂层的热稳定性和光学性能优异。这也为将来制备太阳能吸收涂料提供了新思路。
