摘要
利用纳米压痕和划痕技术对不同纳米硅溶胶含量的两种有机硅耐磨涂层的表面与体相的纳米力学性能和耐磨性分别进行了对比实验研究。结果表明:纳米硅溶胶会增加涂层Si-O-Si网络结构的刚性,提高涂层的力学性能和耐磨性,并且涂层近表面区的硬度、模量以及耐磨性明显优于体相的性质。
Two kinds of transparent scratch-resistant coating with different silica sol contents were synthesized,and their nanomechanical and nanotribological properties from the surface to bulk regions were investigated.The results show that the improvements of the mechanical properties are ascribed to the performance of nanosilica sol and the increased Si-O-Si inorganic bonds.Meanwhile,the hardness,modulus and friction-resistance of coatings in the bulk region are lower than that of surface region.
