The Preparation and Performance of LC4 Aluminum Alloys Ceramic Coatings with Trace Loose Layer Treated by Micro-Arc Oxidation

Abstract:

LC4 aluminum alloy samples were treated by micro-arc oxidation (MAO) to produce trace loose layer film to improve the surface properties. The mechanical characteristics, high temperature erosion performance, structure and composition were investigated by strength tester, high flame erosion, scanning electron microscopy and energy-dispersive X-ray spectrometry. Compared to the untreated aluminum alloy, MAO coatings have good mechanical performance with tensile strength bigger than 18MPa and is intact with 20s heat ablation of 1900°C.
