Opis:: The determination of fracture toughness of aluminium alloy aviation parts, exposed to cyclic mechanical loading, is an important engineering issue. The service life and crack resistance of such unprotected metallic parts is limited under corrosive operating conditions. The resistance against fracture cracking and corrosion resistance can be increased by the surface coatings. The scientific research of fracture toughness of coated metallic parts is being carried out in a comprehensive way. In this research, fracture toughness behaviour of high velocity oxy-fuel (HVOF) spray coated and conventional hard chrome plated aluminium-zinc alloy parts were compared and the results are discussed. The fracture surfaces are investigated and fracture toughness values are calculated. Electron microscopy analysis revealed significant differences in crack growth morphology and toughness values. As a result, the fracture toughness value is higher in hard chrome plated parts.

Opis:: Being a light metallic engineering material with low density, high specific stiffness and strength, aluminium alloys are promising materials in the fields of aerospace, military and automotive industries. Consumption of aluminium alloys in the forms of sheets and plates has generally increased in global markets over the past 45 years. Rolling directions affect the anisotropy and mechanical properties of the aluminium alloys. In this work, the plane strain fracture toughness KIC values of 7075 aluminium alloy were measured in plates of three directions and six orientations (L-T, T-L, T-S, S-T, L-S, S-L), using the standard (ASTM E399) compact tension specimens. The results indicate that dependence of fracture toughness of 7075-T651 aluminium alloy on rolling direction is obvious and that KIC values of T-S and L-T orientations are the highest.
