Influence of titanium-coated (B4Cp + SiCp) particles on sulphide stress corrosion and wear behaviour of AA7050 hybrid composites (for MLG link)
Tóm tắt
The high-strength Al-Zn-Mg-Cu alloy (AA7050) used in manufacturing of main landing gear links in aerospace application and found to have failures in its application due to deterioration in material property (wear and SCC). In this work, an attempt was made to replace AA7050 with AA7050 hybrid composite material fabricated through stir casting. The AA7050/B4Cp/SiCp hybrid composites were prepared with 7.5 wt.% boron carbide particles added with 2.5, 5, 7.5 and 10 wt.% of silicon carbide. Addition of potassium titanium fluoride (K2TiF6) flux improved the bonding of matrix and reinforcement due to the titanium interface. The effect of percentage reinforcement on mechanical wear and sulphide stress corrosion cracking (SSCC) were analysed. The composite with 2.5% of silicon carbide offers better resistance to wear. The stress corrosion and wear mechanisms were studied with the aid of scanning electron microscopy. The hybrid composite showed enhancement in tensile strength owing to the clear bonding of matrix and the reinforcements. The reinforced composites showed improvement in SSCC due to grain boundary precipitates.
