为了简化抗氧化涂层的制备工艺，采用磷酸盐溶液浸渍法制备了C/C和C/SiC盘上的磷化涂层。研究了摩擦表面磷化涂层对C/C和C/SiC摩擦性能的影响。结果表明，在干燥条件下，摩擦表面磷化处理严重降低了C/C的平均摩擦系数(COF)，但对C/SiC的摩擦性能有利。对于C/SiC，摩擦表面磷化处理提高了COF的稳定性，降低了线磨损率。在淡水条件下，摩擦表面磷化涂层在首次制动时会导致C/SiC材料的摩擦系数略有下降。并建立了相应的磨损机理。
In order to simplify the preparation process of anti-oxidation coating, the phosphate coating was prepared on C/C and C/SiC disks by using phosphate solution dipping method. The effects of friction-surface phosphate coating on friction performance of C/C and C/SiC were investigated. In dry condition, the results showed that friction-surface phosphate coating decreased the average coefficient of friction (COF) of C/C seriously, however, was beneficial to the friction performance of C/SiC. For C/SiC, friction-surface phosphate coating enhanced the stability of COF, lowered the linear wear rate. In freshwater condition, friction-surface phosphate coating would cause to a small fading of the COF of C/SiC at the first braking. And relevant wear mechanisms were established.
