现代军事和空间技术中，光学整流罩服役环境变得愈来愈苛刻，会承受如气动冲

In modern military and space technology, the service environment of the optical fairing has become more and more demanding, and it will withstand erosion such as aerodynamic impact, raindrops and sand and gravel, and it is very prone to optical performance failure and surface damage, which will affect combat performance. In this paper, a magnetron sputtering technique was used to prepare a smooth, dense and uniform diamond-like film on the surface of a certain missile infrared optical fairing. The scanning electron microscope, UV-3600 spectrophotometer, IRPrestige-21 Fourier infrared spectrometer, and micro friction and wear tester were used to analyze the morphology, thickness, optical and wear resistance of the diamond-like carbon film. Effectively improve the transmittance of the 1064nm working band of the fairing laser, increase the transmittance of the (3-5)μm infrared band, and the silicon-doped diamond-like film can improve the surface adhesion of the film layer, reduce the stress in the film layer, and improve the film The layer hardness effectively improves the optical performance and surface wear resistance of the fairing.

In modern military and space technology, the optical rectifier service environment has become more and more demanding, and it will withstand such as pneumatic impact, raindrops and sand erosion, which can easily result in optical failure and surface damage, thus affecting operational performance. In this paper, a smooth, dense and uniform diamond-like film is prepared on the surface of an infrared optical rectifier of a certain missile using magnetically controlled sputtering technology.

In modern military and space technology, the service environment of optical fairing becomes more and more severe. It will bear the erosion of aerodynamic impact, raindrop and sand, and it is very easy to have optical performance failure and surface damage, thus affecting the operational performance. In this paper, the diamond-like carbon (DLC) films with smooth, compact and uniform properties were prepared on the surface of the infrared optical fairing of a missile by magnetron sputtering. The morphology, thickness, optical properties and wear resistance of the diamond-like carbon films were analyzed by means of SEM, uv-3600 spectrophotometer, irprestige-21 FT-IR spectrometer and Micro Friction and wear tester. The results show that the diamond-like carbon films can effectively improve the transmittance of the 1064nm working band of the fairing, the transmittance of the (3-5) μ m infrared band, and silicon-doped diamond-like carbon films Stone film can improve the surface adhesion of the film, reduce the internal stress of the film, improve the hardness of the film, and effectively improve the optical properties and surface wear resistance of the fairing.
