“…Especially, the properties of these coatings could be modified by using the additive particles. So, the type and quality of the additive particles are the important factors to modify the mechanical/chemical properties of the coatings [1][2][3][4][5][6][7][8]. For example, using of the silicon carbide particles (~30 μm in diameter) in a nickel-base composite coating, achieved good wear resistance and appropriate corrosion resistance [9].…”

The study has explored the physical and chemical properties of nickel‐boron/nano‐diamond composite coatings upon pre/post heat treatment. The nano‐composite coatings were produced by electroless plating. In fact, the effects of using the nano‐diamond additives (0 g l−1, 0.1 g l−1, 0.3 g l−1, 0.5 g l−1, 0.7 g l−1) were investigated in pre/post heat treatment. According to the results, the micro‐hardness of the nickel‐boron/nano‐diamond composite coating produced in the bath containing 0.5 g l−1 nano‐diamond additive reached to 1005 HV 0.05 upon post‐heat treatment. Also, the corrosion resistance of the nickel‐boron/nano‐diamond composite coatings was modified by using the nano‐additive or heat treatment. But, adding nano‐diamond particles reduced the ductility and wear resistance of the nickel‐boron coatings. We also found, modification of the properties (ductility and wear resistance) of the composite coatings was achieved by using the heat treatment.

“…Moreover, the average size of the additive particles was considered in many studies [3][4][5][6][7][8][9][10][11]. For instance, A research focus was evaluation the effects of the silicon carbide particles of different sizes (50 nm, 60 nm, 300 nm and 500 nm) in the nickel-base composites [12].…”

“…Chemical coatings on Ni-P alloys can improve the surface quality of mirrored substrates via surface modification and processing [7,8]. Ni-P layers enable several processing techniques (e.g., SPDT, chemical mechanical polishing (CMP), magnetorheological finishing (MRF), and ion beam figuring) for reducing the roughness of the optical surface).…”

The surface of metal mirrors is often polished by electroless coating with a Ni–P modified layer after single-point diamond turning. In practice, however, improvements in mirror quality are closely related to the polishing environment, polishing medium, and polishing force. If not adequately controlled, processing defects such as visible scratches can lead to the deterioration of surface roughness. Based on the Ni–P modified surface of a metal reflector mirror, this study optimizes the configuration of magnetorheological figuring (MRF) fluid and polishing process parameters so that MRF high-efficiency surface modification can be realized and the scratch problem can be resolved. The processing method of a high-performance metal mirror is developed by studying the high-efficiency and high-precision processing technology based on small head smoothing. The surface roughness achieved by the proposed method was better than Ra = 0.39 nm. The ultrasonic cleaning process effectively improved the surface roughness after processing. According to the combined processing technology developed in this study, the modified layer of the parabolic mirror with a diameter of 370 mm was processed, and the surface quality was increased from RMS = 338.684 nm to RMS = 21.267 nm.
