Chemically Bonded Composite Sol-Gel Alumina Coatings

This investigation is concerned with the mechanical property enhancement of the steel alloy by deposition of alumina coating using dip coating method. Alumina coatings were deposited using oxime-modified aluminum(III) isopropoxide as a sol–gel precursor. The Scanning electron microscopy (SEM) images of the coated samples suggest deposition of uniform alumina coatings and alumina composition over steel alloy. The mechanical property of the bare, dip coated steel alloy samples were investigated by the slow strain rate test (SSRT). The SSRT indicates that dip coated steel alloy shows higher ultimate tensile strength as compare to the bare samples.

Sol Gel Method

Alumina coating on carbon fibre were prepared by Sol-gel method, and characterized by thermal gravimetric analysis, X-ray diffraction and scanning electron microscopy. Affected factors such as coating times, oxidation temperature and time were investigated. The results show alumina coatings on carbon fibres are crack-free with a smooth surface, therefore would improve anti-oxidation of carbon fibre significantly. Thickness is one of the most important factors on anti-oxidation of alumina coating, and in this work, thicker coatings have better anti-oxidation quality.
