摘要
为了探究氨基硅烷改性对涂层性能的影响及其在功能性涂层领域的应用潜力,采用了氨基硅烷改性技术对不锈钢片基材进行改性,制备了具有不同改性程度的功能性涂层。通过原子力显微镜(AFM)、力学性能测试和热重分析等方法对涂层的表面形貌、力学基本参数和热稳定性进行了全面评价。经过氨基硅烷改性后的涂层性能在力学性能方面显著提升,拉伸强度从80 MPa增至120 MPa,抗压强度从120 MPa提高到了180 MPa,弹性模量从2.5 GPa增至3.8 GPa,表面粗糙度从1.35μm降至0.85μm。此外,涂层的热稳定性也得到一定程度的改善,但在高温环境下仍呈现出一定的质量损失,质量损失率从100℃的0.2%增至600℃的5.2%。通过氨基硅烷改性技术成功改善了涂层的力学性能和表面形貌,提高了涂层的热稳定性。改性后的钢材较改性前价格增长300%,这对于涂层在工程领域的应用具有重要意义,特别是在高强度、耐腐蚀和耐高温要求较高的领域有潜在的应用前景。未来的研究可进一步优化氨基硅烷改性涂层的配方和工艺,以提高其在各种工程应用中的性能。
In order to explore the impact of aminosilane modification on coating performance and its potential applications in functional coatings,aminosilane modification technology was employed to modify stainless steel substrates,functional coatings with varying degrees of modification were obtained.Comprehensive evaluations of the coatings'surface morphology,fundamental mechanical parameters,and thermal stability were conducted using atomic force microscopy(AFM),mechanical property tests,and thermogravimetric analysis.The coatings modified with aminosilane exhibited significant improvements in mechanical properties,tensile strength increased from 80 MPa to 120 MPa,compressive strength rose from 120 MPa to 180 MPa,and the elastic modulus grew from 2.5 GPa to 3.8 GPa.Additionally,the surface roughness was reduced from 1.35μm to 0.85μm.The thermal stability of the coatings also improved,although there was still some mass loss at high temperatures,with the rate of mass loss increasing from 0.2%at 100℃to 5.2%at 600℃.The successful application of aminosilane modification technology enhanced the mechanical performance and surface morphology of the coatings,as well as their thermal stability.The price of the modified steel increased by 300%compared to that before the modification,which had significant implications for the use of coatings in engineering,particularly in areas that demand high strength,corrosion resistance,and high�temperature endurance.Future research should further optimize the formulation and processes of aminosilane-modified coatings to enhance their performance in various engineering applications.
