摘要：

A new technique of depositing a hard ceramic coating onto stainless steel substrate by irradiating sol gel dry alumina films using laser technology has been successfully achieved. The phase composition, crystalline structure and surface morphology of laser-deposited alumina coatings on the substrate surface were characterised by ATR-FTIR, XRD, SEM and EDS, whilst the mechanical properties of the alumina-coated surface were measured using nano-indentation. The results show that laser irradiation of dry alumina films led to the deposition of crystalline alumina coating in alpha-Al2O3 form on substrate surface. Nano-indentation measurements reveal that the mechanical properties of the alumina-coated surface are significantly improved and reach the same level as pure alpha-alumina ceramic.
